Haier Microwave shuts off after a few seconds

When your Haier microwave shuts off after a few seconds, an intermittently failing door switch is the most likely cause. Inspect the primary door switch, secondary door switch, monitor switch, or interlock switch for overheating, arcing, burning, or other damage, then test each switch for continuity with a multimeter. Replace any switch that is damaged or has intermittent continuity. A failing micro switch can cause the same symptom, so inspect and test those switches as well. If the door switches and micro switches test good, the main control board may be faulty, although control boards are often misdiagnosed. Check the touchpad and control panel next. If some buttons respond while others do not, replace the touchpad and control panel. A defective touchpad alone is less common but possible when the display works and only certain buttons respond. Before replacing any control board, verify the other components work properly. Enter your model number to find the exact replacement part for your Haier microwave. Any repair requiring removal of the outer cabinet exposes a high-voltage capacitor that can store a lethal charge even after the microwave is unplugged. The capacitor must be properly discharged before interior work, so hire a qualified technician if you are not familiar with that procedure.

01 - Haier 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.

03 - Haier Microwave Main Control Board

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 - Haier 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.

Highly Likely

05 - Haier 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.
