Service Manual
Never touch any part in the circuit with your hand or an uninsulated tool while the power supply is connected.
When troubleshooting the microwave oven, it is helpful to follow the Sequence of Operation in performing the checks. Many of the possible causes of
trouble will require that a specific test be performed. These tests are given a procedure letter which will be found in the "Test Procedure" section.
IMPORTANT:
If the oven becomes inoperative because of a blown weak point F1 (or F2), check the monitor switches SW3 (or SW4), primary interlock relay RY1,
door sensing switch SW5 and secondary interlock switch SW1 (or SW2), before replacing the weak point F1 (or F2).
