Admiral Microwave shuts off after a few seconds

If your Admiral microwave shuts off after a few seconds, the most likely cause is a failing door switch. Inspect each door switch for overheating, arcing, or burn marks, then use a multimeter to check continuity. Replace any switch that is visibly damaged or tests intermittently. A failing micro switch can cause the same symptom, so test and inspect each micro switch as well. If the switches work properly, the main control board may be defective, but it is often misdiagnosed and should be checked only after the door switches and other components test good. A faulty touchpad and control panel, or touchpad, is less common but possible, especially when the display works and some buttons respond while others do not. These checks can help explain why your microwave stops after 3 seconds, microwave turns off after a few seconds, or microwave keeps shutting off. Opening the outer cabinet requires caution because the high-voltage capacitor can store a lethal charge even after the microwave is unplugged. It must be properly discharged before interior work, so use a qualified technician if you are not familiar with capacitor discharge procedures. Enter your model number to find the exact replacement part for your Admiral microwave.

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.

05 - Admiral Microwave Touchpad

If the microwave runs for a few seconds and stops the touchpad might be at fault. This is not common. Generally speaking, if the microwave display is working and some of the buttons respond correctly but some don’t, the problem is with the touchpad.
