wiring back to the oven power relay. If voltage is

 

 

present, check for 24 VAC at the transformer

 

 

secondary. If there is primary voltage but no

 

 

secondary voltage, replace control transformer.

 

Conveyor motor

Check for 120 VAC supply to the conveyor motor

 

 

at wire #14 to neutral. If no voltage is present,

 

 

trace wiring back to the primary of the control

 

 

transformer. If voltage is present and the motor

 

 

will not run, check the motor windings for opens or

 

 

shorts.

 

 

WITH POWER OFF: Check the motor windings as

 

 

follows:

 

 

Grey to black - 38Ω approx.

 

 

Grey to blue - 38Ω approx.

 

 

Blue to black - 75Ω approx.

 

 

If any of the above fails, 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 120VAC supplied to the motor, and the

 

 

motor, capacitor, and reversing switch check

 

 

good, replace the oven control.

Conveyor motor runs, but

NOTE: Display will indicate

 

there is no speed display

Oven control

Check for output voltage from oven control to hall

 

 

effect sensor (sensor is located in 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

 

 

present at the oven control, replace the 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 at 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.
