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
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 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.
