Caloric Microwave shuts off after a few seconds

If your Caloric microwave shuts off after a few seconds, an intermittently failing door switch is the most likely cause. 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 tests intermittently. A failing micro switch can cause the same symptom, so check and test those switches as well. If the door switches and micro switches work properly, the main control board may be defective, although control boards are often misdiagnosed. Next, check the touchpad and control panel. If some buttons respond while others do not, replace the touchpad and control panel. A faulty touchpad alone is less common, but it can make the microwave stop after a few seconds when the display works and only certain buttons respond. If all other components test good, the control board may need replacement. Enter your model number to find the exact Caloric replacement part for your 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, and a qualified technician should perform the repair if you are unfamiliar with the procedure.

01 - Caloric 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.

05 - Caloric 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.
