E-Wave Microwave shuts off after a few seconds

An E-Wave microwave that shuts off after a few seconds, stops after 3 seconds, or turns off after 2 seconds most often has a failing door switch. Inspect the primary, secondary, and monitor door switches for overheating, arcing, or burning, then test each switch for continuity with a multimeter. Replace any switch that is damaged or has intermittent continuity. A micro switch can cause the same microwave shuts off after a few seconds symptom, so test and replace it if necessary. If the switches work properly, the main control board may be at fault, 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 separate touchpad failure is less common, but possible when the display works and only certain buttons respond. If all other parts test good, the control board may need replacement. Enter your model number to find the exact E-Wave replacement part for your microwave. Any repair that requires removing the outer cabinet carries a serious risk because the high-voltage capacitor can store a lethal charge even when unplugged. It must be properly discharged before interior work, so use a qualified technician if you are not familiar with capacitor discharge procedures.

01 - E-Wave 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 - E-Wave 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 - E-Wave 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.

05 - E-Wave 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.
