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
readings should be approx. 20 – 525 Hz. If these
readings are not achieved, replace the 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.
