Troubleshooting Guide
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 monitor fuse, check the monitor switch,
relay (RY1) primary interlock switch and secondary interlock switch before replacing the monitor fuse. If
monitor fuse is replaced, the monitor switch must also be replaced. Use part FFS-BA016/KIT as an assembly.
IMPORTANT:
Whenever troubleshooting is performed with the power supply cord disconnected. It may in
some cases, be necessary to connect the power supply cord after the outer case has been removed, in this
event:
1. Disconnect the power supply cord, and then remove outer case.
2. Open the door and block it open.
3. Disconnect the leads to the primary of the inverter unit.
4. Ensure that the leads remain isolated from other components and oven chassis by using insulation
tape.
5. After that procedure, reconnect the power supply cord.
When the testing is completed:
1. Disconnect the power supply cord, and then remove outer case.
2. Open the door and block it open.
3. Reconnect all leads removed from components during testing.
4. Reinstall the outer case (cabinet).
5. Reconnect the power supply cord after the outer case is installed.
6. Run the oven and check all functions.
