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.
