Montgomery Wards Microwave shuts off after a few seconds

If your Montgomery Wards microwave shuts off after a few seconds, stops after 3 seconds, or keeps turning off during a cycle, start with the door switches. A failing door switch can intermittently lose continuity, especially if it shows overheating, arcing, or burned marks. Next, check the micro switch, which can cause the same microwave turns off after a few seconds symptom. Use a multimeter to test each switch for continuity and replace any switch that is damaged or tests intermittently. If the switches work properly, the main control board is the next likely cause, but control boards are often misdiagnosed. A faulty touchpad and control panel can also stop the microwave when some buttons respond while others do not. A separate touchpad failure is less common but possible when the display works and only certain buttons respond. Before replacing a control board, verify the switches and touchpad. Enter your model number to find the exact Montgomery Wards replacement part for your microwave. Any repair requiring the outer cabinet to be removed must be handled carefully because the high-voltage capacitor stores a lethal charge even after the microwave is unplugged. It must be properly discharged before interior work, and this repair may require a qualified technician if you are not familiar with capacitor discharge procedures.

A door switch might be failing intermittently. Check each of the door switches for signs of overheating, arcing, or burning. If you don’t see any obvious signs of failure, use a multimeter to test each switch for continuity. If any of the switches is visibly damaged or only has intermittent continuity, replace it.
