1.2 Theory of Operation
The cabinet operates on 208-250VAC 50 or 60 cycle single-phase power. The main switch activates
a relay, which supplies line voltage to two distribution boards, three cooling fans and a power
supply. The power supply provides 5VDC to the master control board and the distribution boards.
A ribbon cable connects the master control board to both distribution boards. Ribbon cables also
connect the distribution boards to the displays. The resistance of RTD’s, attached to the heater
plates, is monitored by the distribution boards. The board switches power through solid-state relays
to the heater plates when the resistance, which is used as an indicator of temperature, falls out of the
range for the product held in the cabinet.
The switch, relay, master control, master control board, LON board, LON filter, cooling fans and
power supply are mounted under the top of the unit. The cabinet is programmed using the key pad
on the front bezel.

done automatically by the cabinet on startup. Communication errors can occur on start-up after a
board installation however. If so, follow the instructions below to readdress the cabinet. This process
can also be used during troubleshooting when displays are connected out of synch with their
associated bezel on the same row level.

suspect heater. Note: Line voltage is only seen when the row is calling for heat.
2. Check for line voltage between the
power input terminal and the terminal
block.
3. Check for +5VDC at the power-in
terminal and the terminal block for the
power supply.
NOTE: After testing, reconnect all
connections to their original positions.
2.5.4 Display
1. Remove power from unit.
2. Connect the ribbon cable from a
suspect display to the connector of a
properly working display to isolate the
problem to the display or the
distribution board.
3. Reapply power to cabinet.
2.5.5 Shorted Triac
Fig. 6: Distribution board shown with display cables removed. 1. Turn the suspect row off and measure
voltage between the suspect heater lead on the distribution board and the terminal block. With
the row off, there should be no line voltage. If the triac is shorted, you will measure AC line
voltage. If the triac is half waving, you will get DC voltage of approximately one-half the line
AC voltage.
2.5.6 Heater Plate
1. Disconnect power to the cabinet. Remove side and top panels. Disconnect the black heater lead
and the RTD leads (brown and red) of the suspect plate from distribution board. Measure
resistance of the heater from the black lead to any terminal on the white terminal block.
Resistance should be 140-150 ohms.
2. Measure resistance across the brown and red RTD leads. Resistance must be within a range of
104-148 ohms. Resistance at room temperature is approximately 107 ohms. See chart on Page
2-4 for resistance at different temperatures. If either resistance is incorrect, replace the heater
plate.
2.5.7 Display Meanings
1. ROW TEMP HIGH OR ROW TEMP LOW and no audible alarm. This is normal when
the row is changing temperature in association with a menu change.
2. LLLL means the RTD indicates a temperature below 50°F (10°C). Unit will automatically heat
at 20 percent until temperature is above 50°F (10°C), then operate normally.

Cabinet Service Procedures
3. HHHH means RTD indicates the temperature is above 255°F (124°C), but below "Open" circuit
resistance, which causes SENS ALARM.
4. UHC VERSION _ _ _ (version number will vary)
appears for five seconds when the unit is turned on.
5. The cabinet also displays a variety of error messages, which are
shown on page 3-1.
2.6 Removing/Replacing Bezels
1. Remove power from unit.
2. Remove screws at the base of each side and remove side
panels. (See figure 7.)
3. Unplug the bezel from the distribution board.

5. Remove replacement bezel and remove power from the unit.
6. Loosen the hex nut which secures the row and remove the allen screw, which holds the
bezel. Also remove, if present, the small bezel-securing screw. (See photo below.)
7. Push, if necessary, on the mounted bezel through the access port in the inner panel to
loosen the bezel. (See Figure 8 below.)
8. Remove bezel; clean and degrease the groove in the heater plate.
9. Route ribbon cable for the new bezel through the inner panel of the cabinet and press the
new bezel into place. Ensure it is firmly seated and tighten hex nuts and replace allen
screws.
10. Return sides and reposition cabinet for operation.
Fig. 8: Loosen the hex bolt and remove the allen screw (arrows, upper photo). Some row positions may have an additional screw securing the bezel to the cabinet (lower photo). Push through the access port (arrow, upper photo), if necessary, to remove the bezel from the cabinet . 2-9
Cabinet Service Procedures
2.6. 1 Removing/Replacing a Distribution Board or Communication Board
1. Remove power.
2. Remove and mark the wires on the faulty component.
3. Remove the board by lifting it from its
standoffs.
4. Position the new board and attach
wires.
5. Reapply power.
6. Run readdress steps on page 2-4.
2.6.2 Removing a Row
1. Remove the sides and top as shown in
earlier steps. Disconnect the faulty row
from the distribution board, and
terminal block.
2. Remove the bezels on each end of the
affected row, as shown in earlier steps,
and the necessary adjacent bezels to
remove the row.
Fig. 9: A row is shown partially removed from the cabinet. 3. Remove wire wraps from wiring
harness holding heater and control
wires for affected row.
4. Lifting slightly, carefully slide the malfunctioning row out of the cabinet. Do not allow the row
to contact or damage the controls of the unit below (Fig. 9).
2.6.3 Replace Heater Plate/RTD
1. Remove row as shown above.
2. Run your fingers around the outside surface of the row assembly. There are four raised areas.
These are the setscrews, which hold the heater plate to the spacer. Punch holes in the insulation,
directly above the location of the setscrews. (Fig. 10, 11).
3. Use an allen wrench to loosen the four spacer-setscrews along the edges of the plate.
4. Slide the malfunctioning plate out of the spacer.
5. Slide the replacement plate into position. Make
sure the plate is inserted squarely. Tighten set
screws.
6. Route the wires to one end of the row and wire tie
the power wires together. Also wire tie the RTD
wires together. Stand the row on the opposite end
adjacent to the cabinet and feed the wires into the
cabinet.
7. Carefully slide the row far enough into the cabinet
to be stable.
8. On the opposite side, reach into the cavity and Fig. 10, 11: Find the set screws under the foil insulation and push through with an allen wrench. direct the wires through the appropriate grommets
to reach the power and RTD connections on the distribution board.
2-10
Cabinet Service Procedures
9. Slide the row assembly completely into the
cabinet and return the spacers between the heater
plates. Ensure the row is evenly positioned in the
cabinet. There must be sufficient space to allow
the bezel tabs to fit between the outside row plate
and the cabinet interior wall.
10. Replace the bezels.
Fig. 12: The heater plate slides from the insulation. CAUTION
Ensure the heater plate setscrews are tightened securely to the spacer.
Tightening the setscrews will ensure the plate is properly grounded.

Enter service code (see page 2‐1) and switch bottom plate on and off to ensure it is responding to cabinet circuits. Compare plate temperature to displayed temperature. Compare plate RTD resistance to chart on page 2‐4. Switch plate on/off with service code to ensure it is responding to cabinet circuits. With plate on and calling for heat, check amp draw on leads between distribution board and heater plate. Amp draw on a properly functioning plate should be 1.67. Cabinet Troubleshooting
