Estate Microwave shuts off after a few seconds

An Estate 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 burned marks, then use a multimeter to test for continuity. Replace any switch that is visibly damaged or tests intermittently. A failing micro switch can cause the same microwave stops after 3 seconds symptom, so check and test each micro switch as well. If the switches work properly, the main control board may be faulty, although control boards are often misdiagnosed. Next, check the touchpad and control panel by pressing every button. If some buttons respond and 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 these parts test good, the control board may need replacement. Enter your Estate microwave model number to find the exact replacement part for your appliance. Any repair that requires opening the outer cabinet requires caution because the high-voltage capacitor can store a lethal charge after the microwave is unplugged. Properly discharge it first, or have a qualified technician perform the interior repair.
