Install the Door Control

Locate door control within sight of door at a minimum height of 5 feet (1.5 m) where small children cannot reach, and away from moving parts of door and door hardware.

The installation surface must be smooth and flat. If installing into drywall (Figure 1), drill 5/32" holes and use anchors provided. For pre-wired installations (as in new home construction), it may be mounted to a single gang box (Figure 2). NOTE: After installation, a green or amber

indicator light behind the cover will indicate proper connection. If not lit, the Lock and Light features will not function (reverse wires to correct).

1. Strip 7/16" (11 mm) of insulation from one end of bell wire and connect to the two screw terminals on back of door control by color: white wire to WHT and white/red wire to the RED (Figure 3).

2. Remove cover by gently prying at slot in the top of the cover with a small flat head screwdriver (Figure 4).

Fasten with 6ABx1-1/4" self-tapping screws (drywall installation) or 6-32x1" machine screws (into gang box) as follows:

• Drill and install bottom screw, allowing 1/8" (3 mm) to protrude above wall surface.

• Position bottom of door control on screw head and slide down to secure. Adjust screw for snug fit.

• Install top screw with care to avoid cracking plastic housing. Do not overtighten.

• Insert bottom tabs and snap on cover.

NOTE: The push bar may stick if the door control is not mounted on a smooth surface. If a click is not heard when pressing the push bar, loosen the two mounting screws or relocate the door control to a smoother surface.

3. (Standard installation only) Run bell wire up wall and across ceiling to motor unit. Use insulated staples to secure wire in several places. Do not pierce wire with a staple, creating a short or open circuit.

4. Strip 7/16" (11 mm) of insulation from end of bell wire.

Connect bell wire to the quick-connect terminals as follows: white to white and white/red to red (Figure 5).

NOTE: When connecting multiple door controls to the opener, twist same color wires together. Insert wires into quick-connect holes: white to white and red/white to red.

5. Use tacks or staples to permanently attach entrapment warning label to wall near door control, and manual release/safety reverse test label in a prominent location on inside of garage door.

NOTE: DO NOT connect power and operate opener at this time. The trolley will travel to the full open position but will not return to the close position until the sensor beam is connected and properly aligned.

To prevent possible SERIOUS INJURY or DEATH from electrocution:

• Be sure power is not connected BEFORE installing door control.

• Connect ONLY to 24 VOLT low voltage wires.

To prevent possible SERIOUS INJURY or DEATH from a closing garage door:

• Install door control within sight of garage door, out of reach of children at a minimum height of 5 feet (1.5 m), and away from ALL moving parts of door.

• NEVER permit children to operate or play with door control push buttons or remote control transmitters.

• Activate door ONLY when it can be seen clearly, is properly adjusted, and there are no obstructions to door travel.

• ALWAYS keep garage door in sight until completely closed.

NEVER permit anyone to cross path of closing garage door.

Attach the Emergency Release Rope and Handle

• Thread one end of the rope through the hole in the top of the red handle so “NOTICE” reads right side up as shown. Secure with an overhand knot at least 1"

(2.5 cm) from the end of the rope to prevent slipping.

• Thread the other end of the rope through the hole in the release arm of the outer trolley.

• Adjust rope length so the handle is 6 feet (1.83 m) above the floor. Ensure that the rope and handle clear the tops of all vehicles to avoid entanglement. Secure with an overhand knot.

NOTE: If it is necessary to cut the rope, heat seal the cut end with a match or lighter to prevent unraveling.

To prevent possible SERIOUS INJURY or DEATH from a falling garage door:

• If possible, use emergency release handle to disengage trolley ONLY when garage door is CLOSED. Weak or broken springs or unbalanced door could result in an open door falling rapidly and/or unexpectedly.

• NEVER use emergency release handle unless garage doorway is clear of persons and obstructions.

• NEVER use handle to pull door open or closed. If rope knot becomes untied, you could fall.

Electrical Requirements

To avoid installation difficulties, do not run the opener at this time.

To reduce the risk of electric shock, your garage door opener has a grounding type plug with a third grounding pin. This plug will only fit into a grounding type outlet. If the plug doesn’t fit into the outlet you have, contact a qualified electrician to install the proper outlet.

To prevent possible SERIOUS INJURY or DEATH from electrocution or fire:

• Be sure power is not connected to the opener, and disconnect power to circuit BEFORE removing cover to establish permanent wiring connection.

• Garage door installation and wiring MUST be in compliance with ALL local electrical and building codes.

• NEVER use an extension cord, 2-wire adapter, or change plug in ANY way to make it fit outlet. Be sure the opener is grounded.

RIGHT WRONG

If permanent wiring is required by your local code, refer to the following procedure.

To make a permanent connection through the 7/8" hole in the top of the motor unit:

• Remove the motor unit cover screws and set the cover aside.

• Remove the attached 3-prong cord.

• Connect the black (line) wire to the screw on the brass terminal; the white (neutral) wire to the screw on the silver terminal; and the ground wire to the green ground screw. The opener must be grounded.

• Reinstall the cover.

To avoid installation difficulties, do not run the opener at this time.

Install The Protector System

®

The safety reversing sensor must be connected and aligned correctly before the garage door opener will move in the down direction.

IMPORTANT INFORMATION ABOUT

THE SAFETY REVERSING SENSOR

When properly connected and aligned, the sensor will detect an obstacle in the path of its electronic beam. The sending eye (with an amber indicator light) transmits an invisible light beam to the receiving eye (with a green indicator light). If an obstruction breaks the light beam while the door is closing, the door will stop and reverse to full open position, and the opener lights will flash 10 times.

The units must be installed inside the garage so that the sending and receiving eyes face each other across the door, no more than 6" (15 cm) above the floor. Either can be installed on the left or right of the door as long as the sun never shines directly into the receiving eye lens.

The mounting brackets are designed to clip onto the track of sectional garage doors without additional hardware.

Be sure power is not connected to the garage door opener

BEFORE installing the safety reversing sensor.

To prevent SERIOUS INJURY or DEATH from a closing garage door:

• Correctly connect and align the safety reversing sensor. This required safety device MUST NOT be disabled.

• Install the safety reversing sensor so beam is NO HIGHER than 6" (15 cm) above garage floor.

If it is necessary to mount the units on the wall, the brackets must be securely fastened to a solid surface such as the wall framing. Extension brackets (see

Accessories) are available if needed. If installing in masonry construction, add a piece of wood at each location to avoid drilling extra holes in masonry if repositioning is necessary.

The invisible light beam path must be unobstructed. No part of the garage door (or door tracks, springs, hinges, rollers or other hardware) may interrupt the beam while the door is closing.

INSTALLING THE BRACKETS

Be sure power to the opener is disconnected. Install and align the brackets so the sensors will face each other across the garage door, with the beam no higher than 6"

(15 cm) above the floor. They may be installed in one of three ways, as follows.

Garage door track installation (preferred):

• Slip the curved arms over the rounded edge of each door track, with the curved arms facing the door. Snap into place against the side of the track. It should lie flush, with the lip hugging the back edge of the track, as shown in Figure 1.

If your door track will not support the bracket securely, wall installation is recommended.

Wall installation (Figure 2 & 3):

• Place the bracket against the wall with curved arms facing the door. Be sure there is enough clearance for the sensor beam to be unobstructed.

• If additional depth is needed, an extension bracket (see

Accessories) or wood blocks can be used.

• Use bracket mounting holes as a template to locate and drill (2) 3/16" diameter pilot holes on the wall at each side of the door, no higher than 6" (15 cm) above the floor.

• Attach brackets to wall with lag screws (not provided).

• If using extension brackets or wood blocks, adjust right and left assemblies to the same distance out from the mounting surface. Make sure all door hardware obstructions are cleared.

Floor installation (Figure 4):

• Use wood blocks or extension brackets (see

Accessories) to elevate sensor brackets so the lenses will be no higher than 6" (15 cm) above the floor.

• Carefully measure and place right and left assemblies at the same distance out from the wall. Be sure all door hardware obstructions are cleared.

• Fasten to the floor with concrete anchors as shown.

MOUNTING AND WIRING THE SAFETY REVERSING

SENSORS

• Slide a 1/4"-20x1/2" carriage bolt head into the slot on each sensor. Use wing nuts to fasten sensors to brackets, with lenses pointing toward each other across the door. Be sure the lens is not obstructed by a bracket extension (Figure 5).

• Finger tighten the wing nuts.

• Run the wires from both sensors to the opener. Use insulated staples to secure wire to wall and ceiling.

• Strip 7/16" (11 mm) of insulation from each set of wires.

Separate white and white/black wires sufficiently to connect to the opener quick-connect terminals. Twist like colored wires together. Insert wires into quickconnect holes: white to white and white/black to grey

(Figure 6).

ALIGNING THE SAFETY REVERSING SENSORS

• Plug in the opener. The indicator lights in both the

sending and receiving eyes will glow steadily if wiring connections and alignment are correct.

The sending eye amber indicator light will glow regardless of alignment or obstruction. If the green indicator light in the receiving eye is off, dim, or flickering (and the invisible light beam path is not obstructed), alignment is required.

• Loosen the sending eye wing nut and readjust, aiming directly at the receiving eye. Lock in place.

• Loosen the receiving eye wing nut and adjust sensor until it receives the sender’s beam. When the green indicator light glows steadily, tighten the wing nut.

TROUBLESHOOTING THE SAFETY REVERSING

SENSORS

1. If the sending eye indicator light does not glow steadily after installation, check for:

• Electric power to the opener.

• A short in the white or white/black wires. These can occur at staples, or at opener connections.

• Incorrect wiring between sensors and opener.

• A broken wire.

2. If the sending eye indicator light glows steadily but the

receiving eye indicator light doesn’t:

• Check alignment.

• Check for an open wire to the receiving eye.

3. If the receiving eye indicator light is dim, realign either sensor.

NOTE: When the invisible beam path is obstructed or misaligned while the door is closing, the door will reverse.

If the door is already open, it will not close. The opener lights will blink 10 times. See page 16.

Fasten the Door Bracket

Follow instructions which apply to your door type as illustrated below or on the following page.

A horizontal reinforcement brace should be long enough to be secured to two or three vertical supports. A vertical reinforcement brace should cover the height of the top panel.

Figure 1 shows one piece of angle iron as the horizontal brace. For the vertical brace, 2 pieces of angle iron are used to create a U-shaped support. The best solution is to check with your garage door manufacturer for an opener installation door reinforcement kit.

NOTE: Many door reinforcement kits provide for direct attachment of the clevis pin and door arm. In this case you will not need the door bracket; proceed to Step 12.

SECTIONAL DOORS

1. Center the door bracket on the previously marked vertical centerline used for the header bracket installation. Note correct UP placement, as stamped inside the bracket.

2. Position the top edge of the bracket 2"-4" (5-10 cm) below the top edge of the door, OR directly below any structural support across the top of the door.

3. Mark, drill holes and install as follows, depending on your door’s construction:

Metal or light weight doors using a vertical angle iron brace between the door panel support and the door bracket:

• Drill 3/16" fastening holes. Secure the door bracket using the two 1/4"-14x5/8" self-threading screws

(Figure 2A).

• Alternately, use two 5/16" bolts, lock washers and nuts

(not provided) (Figure 2B).

Metal, insulated or light weight factory reinforced doors:

• Drill 3/16" fastening holes. Secure the door bracket using the self-threading screws (Figure 3).

Wood Doors:

• Use top and bottom or side to side door bracket holes.

Drill 5/16" holes through the door and secure bracket with 5/16"x2" carriage bolts, lock washers and nuts (not provided) (Figure 4).

NOTE: The 1/4"-14x5/8" self-threading screws are not intended for use on wood doors.

Follow instructions which apply to your door type as illustrated below and on the following page.

SECTIONAL DOORS ONLY

Make sure garage door is fully closed. Pull the emergency release handle to disconnect the outer trolley from the inner trolley. Slide the outer trolley back (away from the door) about 2" (5 cm) as shown in Figures 1, 2 and 3.

Figure 1:

• Fasten straight door arm section to outer trolley with the

5/16"x1" clevis pin. Secure the connection with a ring fastener.

• Fasten curved section to the door bracket in the same way, using the 5/16"x1-1/4" clevis pin.

Figure 2:

• Bring arm sections together. Find two pairs of holes that line up and join sections. Select holes as far apart as possible to increase door arm rigidity.

Figure 3, Hole alignment alternative:

• If holes in curved arm are above holes in straight arm, disconnect straight arm. Cut about 6" (15 cm) from the solid end. Reconnect to trolley with cut end down as shown.

• Bring arm sections together.

• Find two pairs of holes that line up and join with bolts, lock washers and nuts.

Pull the emergency release handle toward the opener at a

45° angle so that the trolley release arm is horizontal.

Proceed to Adjustment Step 1, page 23. Trolley will re-engage automatically when opener is operated.

• With the door closed, connect the straight door arm section to the door bracket with the 5/16"x1-1/4" clevis pin.

• Secure with a ring fastener.

2. Adjustment procedures, Figure 5:

• On one-piece doors, before connecting the door arm to the trolley, the travel limits must be adjusted. Limit adjustment screws are located on the left side panel as shown on page 23. Follow adjustment procedures below.

• Open door adjustment: decrease UP travel limit

- Turn the UP limit adjustment screw counter-clockwise

4 turns.

- Press the Door Control push button. The trolley will travel to the fully open position.

- Manually raise the door to the open position (parallel to the floor), and lift the door arm to the trolley. The arm should touch the trolley just in back of the door arm connector hole. Refer to the fully open trolley/door arm positions in the illustration. If the arm does not extend far enough, adjust the limit further.

One full turn equals 2" (5 cm) of trolley travel.

• Closed door adjustment: decrease DOWN travel limit

- Turn the DOWN limit adjustment screw clockwise

4 complete turns.

One full turn equals 2" (5 cm) of trolley travel.

3. Connect the door arm to the trolley:

• Close the door and join the curved arm to the connector hole in the trolley with the remaining clevis pin. It may be necessary to lift the door slightly to make the connection.

• Secure with a ring fastener.

• Run the opener through a complete travel cycle. If the door has a slight "backward" slant in full open position as shown in the illustration, decrease the UP limit until the door is parallel to the floor.

NOTE: When setting the up limit on the following page, the door should not have a "backward" slant when fully open as illustrated below. A slight backward slant will cause unnecessary bucking and/or jerking operation as the door is being opened or closed from the fully open position.

ADJUSTMENT STEP 1

Adjust the UP and DOWN Travel Limits

Limit adjustment settings regulate the points at which the door will stop when moving up or down.

To operate the opener, press the Door Control push bar.

Run the opener through a complete travel cycle.

• Does the door open and close completely?

• Does the door stay closed and not reverse unintentionally when fully closed?

If your door passes both of these tests, no limit adjustments are necessary unless the reversing test fails

(Adjustment Step 3, page 25).

Adjustment procedures are outlined below. Read the procedures carefully before proceeding to Adjustment Step

2. Use a screwdriver to make limit adjustments. Run the

opener through a complete travel cycle after each adjustment.

NOTE: Repeated operation of the opener during adjustment procedures may cause the motor to overheat and shut off. Simply wait 15 minutes and try again. If anything interferes with the door’s upward travel, it will stop. If anything interferes with the door’s downward travel

(including binding or unbalanced doors), it will reverse.

Without a properly installed safety reversal system, persons

(particularly small children) could be SERIOUSLY INJURED or

KILLED by a closing garage door.

• Incorrect adjustment of garage door travel limits will interfere with proper operation of safety reversal system.

• If one control (force or travel limits) is adjusted, the other control may also need adjustment.

• After ANY adjustments are made, the safety reversal system

MUST be tested. Door MUST reverse on contact with 1-1/2" high (3.8 cm) object (or 2x4 laid flat) on floor.

To prevent damage to vehicles, be sure fully open door provides adequate clearance.

Cover Protection

Bolt

2-4"

(5-10 cm)

HOW AND WHEN TO ADJUST THE LIMITS

• If the door does not open completely but opens at least five feet (1.5 m):

Increase up travel. Turn the UP limit adjustment screw clockwise. One turn equals 2" (5 cm) of travel.

NOTE: To prevent the trolley from hitting the cover protection bolt, keep a minimum distance of 2-4"

(5 cm - 10 cm) between the trolley and the bolt.

• If door does not open at least 5 feet (1.5 m):

Adjust the UP (open) force as explained in Adjustment

Step 2.

• If the door does not close completely:

Increase down travel. Turn the down limit adjustment screw counterclockwise. One turn equals 2" (5 cm) of travel.

If door still won't close completely and the trolley bumps into the pulley bracket (page 4), try lengthening the door arm (page 21) and decreasing the down limit.

• If the opener reverses in fully closed position:

Decrease down travel. Turn the down limit adjustment screw clockwise. One turn equals 2" (5 cm) of travel.

Left Side Panel Limit Adjustment Screws

Adjustment Label

• If the door reverses when closing and there is no visible interference to travel cycle:

If the opener lights are flashing, the Safety Reversing

Sensors are either not installed, misaligned, or obstructed. See Troubleshooting, page 18.

Test the door for binding: Pull the emergency release handle. Manually open and close the door. If the door is binding or unbalanced, call for a trained door systems technician. If the door is balanced and not binding, adjust the DOWN (close) force. See Adjustment Step 2.

23


Adjust the Force

Force adjustment controls are located on the back panel of the motor unit. Force adjustment settings regulate the amount of power required to open and close the door.

If the forces are set too light, door travel may be interrupted by nuisance reversals in the down direction and stops in the up direction. Weather conditions can affect the door movement, so occasional adjustment may be needed.

The maximum force adjustment range is about 3/4 of a complete turn. Do not force controls beyond that

point. Turn force adjustment controls with a screwdriver.

NOTE: If anything interferes with the door’s upward travel, it will stop. If anything interferes with the door’s downward travel (including binding or unbalanced doors), it will reverse.




• Too much force on garage door will interfere with proper operation of safety reversal system.

• NEVER increase force beyond minimum amount required to close garage door.

• NEVER use force adjustments to compensate for a binding or sticking garage door.



MUST be tested. Door MUST reverse on contact with 1-1/2" high (3.8 cm) object (or 2x4 laid flat) on floor.

HOW AND WHEN TO ADJUST THE FORCES

1. Test the DOWN (close) force

• Grasp the door bottom when the door is about halfway through DOWN (close) travel. The door should reverse.

Reversal halfway through down travel does not guarantee reversal on a 1-1/2" (3.8 cm) obstruction. See

Adjustment Step 3, page 25. If the door is hard to

hold or doesn’t reverse, DECREASE the DOWN

(close) force by turning the control counterclockwise.

Make small adjustments until the door reverses normally. After each adjustment, run the opener through a complete cycle.

• If the door reverses during the down (close) cycle

and the opener lights aren’t flashing, INCREASE

DOWN (close) force by turning the control clockwise.

Make small adjustments until the door completes a close cycle. After each adjustment, run the opener through a complete travel cycle. Do not increase the force beyond

the minimum amount required to close the door.

2. Test the UP (open) force

• Grasp the door bottom when the door is about halfway through UP (open) travel. The door should stop. If the

door is hard to hold or doesn’t stop, DECREASE UP

(open) force by turning the control counterclockwise.

Make small adjustments until the door stops easily and opens fully. After each adjustment, run the opener through a complete travel cycle.

• If the door doesn’t open at least 5 feet (1.5 m),

INCREASE UP (open) force by turning the control clockwise. Make small adjustments until door opens completely. Readjust the UP limit if necessary. After each adjustment, run the opener through a complete travel cycle.

Test the Safety Reversal System

TEST

• With the door fully open, place a 1-1/2" (3.8 cm) board

(or a 2x4 laid flat) on the floor, centered under the garage door.

• Operate the door in the down direction. The door must reverse on striking the obstruction.

ADJUST

• If the door stops on the obstruction, it is not traveling far enough in the down direction. Increase the DOWN limit by turning the DOWN limit adjustment screw counterclockwise 1/4 turn.

NOTE: On a sectional door, make sure limit adjustments do not force the door arm beyond a straight up and down position. See the illustration on page 21.

• Repeat the test.

• When the door reverses on the 1-1/2" (3.8 cm) board, remove the obstruction and run the opener through 3 or

4 complete travel cycles to test adjustment.

• If the unit continues to fail the Safety Reverse Test, call for a trained door systems technician.

IMPORTANT SAFETY CHECK:

Test the Safety Reverse System after:

• Each adjustment of door arm length, limits, or force controls.

• Any repair to or adjustment of the garage door

(including springs and hardware).

• Any repair to or buckling of the garage floor.

• Any repair to or adjustment of the opener.




• Safety reversal system MUST be tested every month.

To Open the Door Manually

To prevent possible SERIOUS INJURY or DEATH from a falling garage door:

• If possible, use emergency release handle to disengage trolley ONLY when garage door is CLOSED. Weak or broken springs or unbalanced door could result in an open door falling rapidly and/or unexpectedly.

• NEVER use emergency release handle unless garage doorway is clear of persons and obstructions.

• NEVER use handle to pull door open or closed. If rope knot becomes untied, you could fall.

The door should be fully closed if possible. Pull down on the emergency release handle and lift the door manually. To reconnect the door to the opener, press the door control push bar.

HAVING A PROBLEM?

1. My door will not close and the light bulbs blink on

my motor unit: The safety reversing sensor must be connected and aligned correctly before the garage door opener will move in the down direction.

• Verify the safety sensors are properly installed, aligned and free of any obstructions. Refer to

Installation Step 10: Install The Protector System

®

.

• Check diagnostic LED for flashes on the motor unit then refer to the Diagnostic Chart on the following page.

2. My remotes will not activate the door:

• Verify your door control is not blinking. If it is blinking, deactivate the Lock Mode following the instructions for

Using the Wall-Mounted Door Control.

• Reprogram remotes following the programming instructions. Refer to Programming.

• If remote will still not activate your door, check diagnostic LED for flashes on motor unit then refer to

Diagnostic Chart on the following page.

3. My door reverses for no apparent reason: Repeat safety reverse test after adjustments to force or travel limits. The need for occasional adjustment for the force and limit settings is normal. Weather conditions in particular can affect door travel.

• Manually check door for balance or any binding problems.

• Refer to Adjustment Step 2, Adjust the Force.

4. My door reverses for no apparent reason after fully

closing and touching the floor: Repeat safety reverse test after adjustments to force or travel limits. The need for occasional adjustment for the force and limit settings is normal. Weather conditions in particular can affect door travel.

• Refer to Adjustment Step 1, Adjust the UP and DOWN

Travel Limits. Decrease down travel by turning down limit adjustment screw clockwise.

5. My lights will not turn off when door is open:

• The garage door opener is equipped with a security light feature. This feature activates the light on when the safety sensor beam has been obstructed. Refer to

Operation section; Using the Wall Mounted Door

Control, Light Feature.

6. My motor unit hums briefly:

• First verify that the trolley is against the stop bolt.

• Release the door from the opener by pulling the

Emergency Release Rope.

• Manually bring the door to a closed position.

• Loosen the chain by adjusting the outer nut 4 to 5 turns. This relieves the tension.

• Run the motor unit from the remote control or door control. The trolley should travel towards the door and stop. If the trolley re-engages with the door, pull the

Emergency Release Rope to disengage.

• Decrease the UP travel by turning the UP Travel adjustment screw 2 full turns away from the arrow.

• Re-tighten the outer nut so the chain is a 1/2" (13 mm) above the base of the rail. (When the door is reconnected and closed, the chain will sag. This is normal.)

• If the trolley does not move away from the bolt, repeat the steps above.

Symptom: One or both of the Indicator lights on the safety reversing sensors do not glow steady.

• Inspect sensor wires for a short (staple in wire), correct wiring polarity (black/white wires reversed), broken or disconnected wires, replace/attach as needed.

• Disconnect all wires from back of motor unit.

• Remove sensors from brackets and shorten sensor wires to 1-2 ft. (30-60 cm) from back each of sensor.

• Reattach sending eye to motor unit using shortened wires. If sending eye indicator light glows steadily, attach the receiving eye.

• Align sensors, if the indicator lights glow replace the wires for the sensors. If the sensor indicator lights do not light, replace the safety reversing sensors.

Symptom: LED is not lit on door control.

• Inspect door control/wires for a short (staple in wire), replace as needed.

• Disconnect wires at door control, touch wires together. If motor unit activates, replace door control.

• If motor unit does not activate, disconnect door control wires from motor unit.

Momentarily short across red and white terminals with jumper wire. If motor unit activates, replace door control wires.

Symptom: Sending indicator light glows steadily, receiving indicator light is dim or flashing.

• Realign receiving eye sensor, clean lens and secure brackets.

• Verify door track is firmly secured to wall and does not move.

Symptom: Motor has over heated; the motor unit does not operate or trolley is stuck on stop bolt = Motor unit hums briefly; RPM Sensor =

Short travel 6-8" (15-20 cm).

• Unplug unit to reset. Try to operate motor unit, check diagnostic code.

• If it is still flashing 5 times and motor unit moves 6-8" (15-20 cm), replace RPM sensor.

• If motor unit doesn’t operate, motor unit is overheated. Wait 30 minutes and retry.

If motor unit still will not operate replace logic board.
