8 

plug to be sure it is firmly in receptacle. Measure 
incoming power, call power co. if required. 

Fuse, 10 Amp 

Check, replace if necessary. 

Fuse holder 

Check, replace if necessary. 

Switch, oven power 

Check for line voltage supplied to switch. If no voltage 
is present, trace wiring back to fuse holder. Check 
continuity between switch terminals. Replace switch as 
needed. 

Control transformer 

Check for supply voltage to primary of control 
transformer. If no voltage is present, trace wiring back to 
oven power switch. If voltage is present, check for 
24VAC at transformer secondary. If there is primary 
voltage, but no secondary voltage, replace control 
transformer. 

Conveyor motor 

Check for supply voltage to the conveyor motor at 
terminal #8 to neutral. If no voltage is present, trace 
wiring back to oven power switch. If voltage is present, 
but the motor will not run, check the motor windings for 
opens or shorts. If any of the above checks fail, replace 
conveyor motor. 

Capacitor, conveyor motor 

Check for shorts or grounds. Replace capacitor as 
needed. 
WARNING: Capacitor has a stored charge, discharge 
before testing. 

Switch, conveyor reversing 

Check continuity between switch terminals. Replace 
switch as needed. 

Oven control 

If there is voltage supplied to the motor, and the motor 
capacitor and reversing switch check good, replace the 
oven control. 

Conveyor motor runs, 
but there is no speed 
display 

NOTE: Display will indicate 
“BELT JAM” 

Oven control 

Check for output voltage from oven control to hall effect 
sensor (sensor is located in the conveyor motor). 
Measure voltage at the motor connector, red wire and 
yellow wire. Voltage should be approx. 10VDC. If no 
voltage is present, trace wiring back to oven control. If 
there is no voltage output at the oven control, replace 
oven control.   

Conveyor motor 

If there is voltage supplied to the hall effect sensor, 
check for a frequency output from the hall effect sensor. 
Measure frequency across the yellow and white wires in 
the motor connector. Frequency reading should be 
approx. 25-100 Hz. If these readings are not achieved, 
replace conveyor motor. If the readings are achieved, 
proceed. 

Oven control 

If the hall effect sensor readings are correct, but there is 
no speed indicated on the display, replace the oven 
control.
