CHAPTER 6. 
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 fuse F10A (F1 or F2) in the interlock switch (SW1 or SW2) - monitor switches (SW3 or
SW4), check the interlock switch (SW1 or SW2) and monitor switches (SW3 or SW4) before replacing the fuse F10A (F1 or F2).
