TROUBLESHOOTING
BASIC FUNCTIONALITY CHECKS
SYMPTOM POSSIBLE CAUSE POSSIBLE CORRECTION
Oven Fans will not
Turn Off
1 Cool Down Operation a The Main Motor (M1) and Cooling Fan (M2) will
operate until the oven cools to 225°F/107°C.
Cannot Adjust
Time or
Temperature
1 A Recipe is Selected a The Control System (UI) must be in “MANUAL”
mode to adjust Time, Temperature and VFD Hz.
Please review the OPERATIONS section for
instructions of how to switch RECIPE modes and
select MANUAL mode.
Conveyor Does
Not Move
1 The Belt is Jammed a This condition produces a “BELT JAM” error. Free
the conveyor motor from the drive chain. If the
problem is resolved, locate, and correct the belt
obstruction.
If NO obstruction is found, ensure the Drive
Chain and Conveyor Belt are not slack, causing
gathering and binding during rotation.
2 Missing Tach Pickup a Check for 5VDC between P6.10 (Red/White) and
P6.9 (Black) on the Control Board (MC).
If missing, replace the Control Board (MC)
3 Motor is Bound (may occur
due to extended periods in
an unused state)
a This condition produces a “BELT LOW SPEED”
error. Measure VDC between on the Control
Board (MC) P6.9 (Black) to P6.5 / P6.4 / P6.3.
If you receive a measurement of 5VDC, the motor
is bound. With the motor unplugged, attempt to
rotate the shaft with a wrench. If the problem is
unresolved, replace the motor.
b Lubricating oil may settle from the internal gear
surfaces over a period of time. An oven which
has not been used for an extended period OR
an oven which is newly installed may experience
initial conveyor motor rotation problems.
Rotate the shaft of the motor slightly to overcome
the friction and lubricate the gearbox.
