If your Hotpoint microwave shuts off after a few seconds, the most likely cause is an intermittently failing door switch. A worn primary, secondary, monitor, or interlock switch may lose continuity as the door moves, causing the microwave to stop after 2 or 3 seconds. Unplug the appliance, inspect each door switch for overheating, arcing, or burned terminals, and use a multimeter to check continuity. Replace any switch that is damaged or tests intermittently. A failing micro switch can cause the same microwave stops after a few seconds symptom, so test and replace it using the same procedure. If the switches work properly, the main control board may be faulty, but control boards are often misdiagnosed and should be checked only after the door switches and other components test good. A defective touchpad and control panel or touchpad is less common, especially when some buttons respond while others do not. Enter your Hotpoint microwave model number to find the exact replacement part for your appliance. Any repair that requires opening the outer cabinet has a serious safety risk: the high-voltage capacitor can store a lethal charge even when unplugged and must be properly discharged. Use a qualified technician if you are not familiar with capacitor discharge procedures.
01 - Hotpoint Microwave Door Switch
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.

A micro switch might be failing intermittently. Check each of the micro 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.
Control boards are often misdiagnosed—before replacing the control board, first check more commonly defective parts, particularly the door switches. If all of the other components are working properly, replace the control board.
04 - Hotpoint Microwave Touchpad and Control Panel
To determine if the touchpad and control panel are defective, try pressing each of the buttons on the control panel. If some of the buttons respond correctly while others don’t, replace the touchpad and control panel.
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.
Control boards are often misdiagnosed—before replacing the control board, first check more commonly defective parts, particularly the door switches. If all of the other components are working properly, replace the control board.
