VENT MOTOR CAPACITOR
the Vent motor capacitor is located directly behind the control panel.
It is in use any time the Vent motor is on. The capacitor helps to maintain a constant voltage to the Vent motor so that it
runs more efficiently.
TEST CHARTS
COMPONET TEST PROCEDURE RESULT
High Voltage Transformer(With wire leads unplugged)
Magnetron(with wire leads unplugged)
NOTE
A microwave energy leakage test must always
be performed when the oven is serviced for
any reason.
NOTE
Replace the magnetron if the checks and all of
the high voltage component tests are good,
but the unit still does not heat a load
