componEnt tEStinG

Exterior panel removal

warninG to prevent hazard in servicing the cooker, be certain that the electrical disconnect circuit breaker for the steamer is off before removing side panels.

Access to all internal plumbing and electrical assemblies is from the right side. The right-side panel is removed by removing the bottom screws from panel.

60-minutE timEr timer contacts

Defective timer contacts will result in failure of cooker compartment to operate. when this occurs, remove the side panel and proceed as follows:

1. Turn off power at external circuit breaker.

2. Disconnect all three wires from timer terminals.

3. connect an ohmmeter between terminals 21 and 22.

4. Rotate timer dial beyond the “0 - minute” point (any setting) to obtain a reading of zero ohms on the ohmmeter. if zero ohm reading cannot be obtained, timer contacts are defective and the timer must be replaced.

5. move ohmmeter leads to terminals 21 and 24.

6. Rotate timer dial to “0 - minute” position. (An audible click indicates correct position). if zero ohm reading cannot be obtained, the timer is defective and must be replaced.

7. move ohmmeter leads to terminals 11 and 12.

8. Rotate the timer dial to the “cOnSTAnT STEAm” position. if zero ohm reading cannot be obtained, the timer is defective and must be replaced.

9. Remove ohmmeter and replace all three leads on timer terminals.

troublEShootinG timer motor

A defective timer motor will cause continuous operation in the TimE mode, with the timer dial failing to return to the

“0 - minute” position.

To confirm timer motor condition, proceed as follows:

1. carefully check motor wire leads and tighten loose connections.

buzzer

if the buzzer does not sound at the termination of the operator-selected timer setting (timer dial returned to “0

- minute” position), the fault may be a defective buzzer.

Buzzer operation is verified using an AC voltmeter at buzzer coil connections with input power on and selector switch and coinciding timer dial set at the “0 - minute” position. if voltage is 240 volts, the fault is in the buzzer, which must be replaced. if 240 volts is not present, the fault is in the wiring or control components (timer or selector switch).

wiring

warninG use care while working with control panel. terminals carry 240 volts.

2. Turn on power to the steamer.

3. Set timer dial (any setting beyond “0 - Minute”). if operation is correct, the motor will turn the dial toward

“0 - minute”. if the motor fails to operate, it is defective and the timer must be replaced.

4. Shut off power to the cooker.

door interlock Switch:

malfunction of the cooker door interlock switch prevents timer indicator lights from turning on and steam generator from operating when the timer dial is set. if steam does not enter the compartment and the cooking indicator light fails to turn on with the door latch securely engaged, the fault may be in the door interlock switch.

Proceed as follows:

1. Turn off power to the cooker.

2. Disconnect wires to the door switch terminals.

3. connect an ohmmeter between the terminals of the switch. The switch is marked “c” for common, “nc” for normally closed and “nO” for normally open.

4. Actuate the switch by closing the cooking compartment door. if a zero reading cannot be obtained between the c and nO terminals, the switch is defective and must be replaced.

5. Remove the ohmmeter and replace the leads on switch terminals.

indicator lights

if the cooker compartment functions correctly, with the single exception that the indicator light fails to light during operation, the fault is a defective indicator light. A “burned out” or defective light is verified by using an AC voltmeter at the leads, with input power on the selector switch in the correct position for that timer, the timer set, and the door latches closed. if 240 volts is present, the fault is in the indicator light and requires replacement. if 240 volts is not present, the fault is in the wiring or control components

(selector switch, timer or door switch).

warninG disconnect the power supply to the appliance before cleaning or servicing.

Using an ohmmeter, wiring continuity between the connections shown on the wiring diagram is readily verified.

This is best done in stages, removing only those wires required for each continuity check. As each lead is replaced, it should be checked for evidence of corrosion, and cleaned if necessary. All leads must be tightly attached so as to provide a good electrical connection.

door Gasket

check gasket for cuts and replace if necessary.

door Gasket replacement

The cooking compartment door gaskets are made of a silicone-type rubber material that is very durable but subject to wear during normal operation. Should the gasket leak replace it.

1. Open the cooking compartment door.

2. Remove the six or eight screws from the gasket plate in the door panel assembly.

3. Remove the gasket plate and the door gasket from door panel.

4. install the new door gasket to the door panel. Replace the gasket plate and six or eight screws.

5. gasket replacement is now complete.

Door may be difficult to close until gasket has compressed to conform to opening. Firmly slam the door, leaving door closed several hours or overnight will compress gasket.

ElEmEnt blocK rEplacEmEnt

1. Disconnect power supply.

2. Ensure the unit is cool and empty.

3. Remove the right side panel by removing two screws near the base of the unit. Lift panel up and away to remove and set aside.

4. Remove top cov er by removing two screws in back of unit. Raise the cover to clear the vent and slide towards the front of the unit to remove. Remove insulation from top of cooker and set aside.

5. Tilt the unit to rest on it’s face using wooden supports to steady the unit. Remove the leftlback panel by removing screws from the base and sliding it towards the back of the unit, upwards in this case and set aside. Remove the insulation from the left side and set aside.

6. Remove two screws that retain the component mounting board, carefully supporting it and saving from damage. Leave it rest at the side of the unit.

7. Remove the unit base by removing four screws near the face of the unit and set aside. Remove the insulation to expose the element plate.

8. Remove the failed element block and residual heat sink compound

9. Apply about 4 ounces of heat sink compound with a

3/16” “V” and pitch of 112” notched trowel across the width of the element block on the contact surface.

Mount the element block to the unit. Using plain flat washers, torque each nut to 100 inch pounds following the recommended pattern. Start back at position one removing the flat washer and replace with two beleville washers and torque to 45 inch pounds using

Loctite #271 thread locking adheasive. Repeat this for each of the rest of the studs.

10. Reassemble the unit using steps 1 through 8 in reverse order.
