Hi chrispeach
Unplug the microwave, open the control panel and make sure the door switches (#10, #23 and #24 on the
interior break down diagram) are properly engaged when the door closed. If not then adjust the interlocks or the door latch.
Also check the door switches them self. With the door closed the primary and the secondary interlock switches must be closed and the monitor switch must be open. If the reading is incorrect, replace the wrong switch.
- The part number for the interlock (they are identical)
AP3779117
- The part number for the upper switch (#10 on the diagram)
AP3918718
- The part number for the inner bottom switch (#23 on the diagram)
AP3885662
- The part number for the outer bottom switch (#24 on the diagram)
AP3890405
- Here are the break down diagrams for the Estate microwave
Model TMH14XMT0
Good luck.
