TROUBLESHOOTING
The following is a list of errors that may occur, probable causes, and corrective action that may eliminate the problem.
If after performing the corrective action the problem persists, contact a service technician
.
Drum Won’t Turn (Error 1)
The controller has detected a CURRENT ERROR FOR THE DRUM MOTOR. The drum motor current draw is
monitored by the controller. A drum motor error will occur if the motor current falls outside the expected values.
A DRUM WON’T TURN error could be caused by disconnected drum motor wiring, a faulty drum motor, or faulty
controller.
Fry Doors Stuck (Error 2)
The controller has detected a CURRENT ERROR FOR THE ACCUMULATOR MOTOR. The accumulator motor
current draw is monitored by the controller. An accumulator motor error will occur if the motor current falls outside the
expected values.
A FRY DOORS STUCK error could be caused by disconnected accumulator motor wiring, a faulty accumulator motor,
or broken accumulator linkage.
Fry Door Failed (Error 3)
The controller has detected a TIMEOUT ERROR FOR THE ACCUMULATOR MOTOR HOME SENSOR. The
accumulator home sensor sends an input to the controller each time the accumulator doors cycle. It lets the controller
know that the doors opened and closed in an acceptable time.
A TIMEOUT ERROR could be caused by an accumulator motor fault, broken accumulator linkage, a disconnected or
faulty accumulator encoder, or a damaged encoder vane. Verify the accumulator encoder wiring at both the board and
at the encoder is secure and the vane is in place and undamaged. Check accumulator linkage to ensure it is
undamaged.
Weighing Issue (Error 4)
The controller has detected a LARGE SHIFT IN THE TARE (EMPTY) READING FOR THE SCALE INPUT. Could be
caused by an obstruction of the scale or loss of calibration. Verify the accumulator housing and flap door are properly
assembled. Check accumulator doors to ensure there are no obstructions (e.g. fries jammed underneath). Verify the
shaft collars are pushed back to the e-clips near the back wall. If no obstruction is found, calibrate the scale
(see page 28).
Cooling Slow (Error 5)
The controller has detected that the CABINET TEMPERATURE IS NOT COOLING AS EXPECTED. Likely causes are
leaving the cabinet door open for extended periods of time during operation, or the power was left on while defrosting
the cabinet. Other possible causes are a restriction to the airflow across the condensing unit such as might occur with
a dirty condenser filter and/or coil, a faulty temperature probe, or a malfunction of the refrigeration compressor. Check
for obstructions near the condensing unit inlet grill and inspect and clean the condenser filter and/or coil if needed (see
page 42). Verify the temperature probe is in place and properly secured. CONTACT A SERVICE TECHNICIAN FOR
ASSISTANCE.
