TROUBLESHOOTING GUIDE
[1] FOREWORD
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 fuse F2 (F8A) in the monitored latch switch SW1 - monitor switch SW3 circuit, check the moni-
tored latch switch SW1 and monitor switch SW3 before replacing the noise filter (fuse F2 (F8A)).
