Dacor Microwave shuts off after a few seconds

If your Dacor microwave shuts off after a few seconds, an intermittently failing door switch is the most likely cause. Inspect each door switch for overheating, arcing, or burning, then use a multimeter to test for consistent continuity. Replace any damaged or intermittent switch. A failing micro switch can cause the same problem, so test these switches as well. If the door switches and micro switches check out, the Dacor main control board may be defective, but control boards are often misdiagnosed and should be replaced only after more common parts are ruled out. A faulty touchpad and control panel or touchpad is less common, especially when the display works and some buttons respond while others do not. This issue is sometimes described as a microwave stops after 3 seconds, microwave turns off after a few seconds, or microwave keeps shutting off. Enter your model number to find the exact replacement door switch, micro switch, main control board, touchpad, or control panel for your Dacor microwave. Any repair requiring removal of the outer cabinet must be handled carefully because the high-voltage capacitor can store a lethal charge even after the microwave is unplugged. Proper capacitor discharge is required before interior work, and a qualified technician should perform the repair if you are not familiar with that procedure.

01 - Dacor 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 - Dacor 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.

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 - Dacor 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.
