QUALIFIED SERVICE TECHNICIAN CHECK:
A) Check that there is power at receptacle. Verify voltage is correct based upon the voltage listed on
the toaster nameplate.
B) WITH POWER OFF check connections inside of plug. Remove right side panel and check wiring.
Any wires or terminals with burns or discoloration from arcing should be replaced. All wiring, if
replaced, should be same or higher rated wire.
C) Check sensors to see if ohm readings correct. At room temperature (70˚F), should be nominal
1.09K ohms.
D) With toaster off, check for continuity across the solid state relay terminals #1 and #2. Normal
readings are in megohm range. If reading ohms, relay has failed closed and will not cycle.
E) Control Generation 2 if no LED on display, check for .5 amp transformer fuses. If fuses good,
check for 208 volts on terminals 1 and 6, then 18 Vac on 11 and 12. If 208 volts is present and no
18 Vac output, replace transformer.
2. PROBLEM: Conveyor belts move but no heat.
SOLUTION:
QUALIFIED SERVICE TECHNICIAN CHECK:
A) Check that there is power at receptacle. Verify voltage is correct based upon the voltage listed on
the toaster nameplate.
B) Check for loose connections at terminal strip and temperature terminals (see schematic).
C) Verify that the heater and sensor wires are connected to the controller.
D) Replace all connections or components that have damaged terminals. Replace any damaged
wiring with same or higher rated wire.
E) Check the resistance of the sensor(s). If sensor is open, replace. At room temperature (70˚F),
should be nominal 1.09K ohms.
F) Check voltage into solid-state relays. The voltage input from module should be approximately
5Vdc. Voltage to heater should be 208 or 240Vac.
G) Check the resistance of the heater platens: 24 ohms at room temperature.
H) Control Generation 2 – Check for 24Vdc to the heater relay (R1, R2) from the control board. If
getting 24Vdc from the control board, check for 208 volts on output side of relay. If no 208 volts
then replace relay. If there is 208 volts, then possible solid state relay problem.
3. PROBLEM: Heater platens are hot, control says LO or RDY, conveyor belts do not move.
SOLUTION:
A) Make sure carriage is seated in saddles and top slots are around locator pins.
B) Remove conveyor carriage and turn conveyors by hand and determine there is no binding due to
dropping carriage.
C) Make sure all setscrews on gears are tight.
D) Check motor to make sure it is turning with carriage removed.
E) Increase belt tensioning by loosening tension bracket screws, push toward end as you retighten
screws. If bracket is at the end of adjustment, it is necessary to remove one conveyor link. See
Figure 5.
F) Conveyor carriage has been dropped, bent. Replace carriage.
QUALIFIED SERVICE TECHNICIAN CHECK:

B) Check the fuses inside the right panel. Replace with type AGC 1.5 amp fuse if necessary.
C) Check for voltage to speed control board. Check for voltage to the motor.
D) Check for red light on the speed board. If red light is lit, the motor is working too hard or in a
stalled state.
E) Some speed boards have a green light. If green light is lit then power is going to the board.
F) Make sure each voltage slide switch of the speed board is set at 230V and 90V as labeled on
the speed board.
G) Check for DC voltage out of board to motor.
H) Check all wiring to motor for loose connectors.
4. PROBLEM: Variable Speed Motor Not Operating
SOLUTION:
QUALIFIED SERVICE TECHNICIAN CHECK:
A) Verify correct voltage to toaster and motor.
B) Check 1.5-amp fuses (#500061) inside right control panel. Replace if necessary.
C) Check for DC voltage to motor out of board (90VDC Motor).
D) If red light on board is on, disconnect load from motor by removing conveyor carriage. If it
goes out, look for conveyor or motor binding. If it stays lit, replace motor – there is probably a
gearbox problem.
E) Check DC amp draw to motor by putting meter in series with motor. (Pull wire from A1 on
board, put one lead to A1, other to wire pulled from A1.) When red LED on board is on, DC
amp reading should be .3 amps approximately.
F) If green LED is on and red is not, make sure that there is varying DC voltage out of board to
motor (terminals A1 & A2 on board) as speed control knob is increased or decreased.
G) Check for oil leaks on motor signifying bad seal or overheating that has taken place. In either
case, motor should be replaced.
H) Check ohm reading at motor cord plug (Range between 50-80 Ohms).
5. PROBLEM: Circuit Board not working properly. DO NOT ADJUST POTS ON BOARD!
SOLUTION:
QUALIFIED SERVICE TECHNICIAN CHECK:
A) Verify AC voltage to board and DC voltage to motor from board. If there is AC voltage in, but
no DC voltage out, replace board.
B) Check all connections on board and terminal strip.
C) Verify that board is wired correctly. (See schematic in Owner’s Manual.)
D) Make sure that one slide switch on board is in 230V position and other is in 90V position.
E) Make sure all wires are connected to potentiometer. A loose wire will make toaster run at
single uncontrolled speed.
F) Control Generation 2 – Check for 24 Vdc from control board to motor relay (R3). If relay is getting
24 Vdc, check for 208 volts on output side of relay. If no 208 volts, replace relay.
6. PROBLEM: Product is over or under toasted.
SOLUTION:
A) Check the gap settings. There must be compression of the bun as it feeds into the toaster.
Decreasing the gap will increase bun temperature and darken surface color. To lower
(decrease gap) turn knob counter-clockwise; to raise (increase gap) turn knob clockwise.
B) Check toast time. Time should be approximately 65 seconds nominal from start to finish.
