How to Diagnose a Microwave Problem Before Calling
Run through these checks before calling — you may save a service visit. If the issue persists, we're ready for same-day service.
- 1
Test a different outlet or reset the GFCI
Many over-the-range microwaves share a GFCI-protected circuit. Press the RESET button on the outlet (sometimes under the sink) before assuming the microwave has failed.
- 2
Inspect the door switches
Microwaves have two or three safety switches in the door latch. Open and close the door firmly. If the latch feels loose or the microwave won't start with the door closed, a switch has likely failed.
- 3
Check the turntable and drive motor
Remove the glass tray and roller ring and place them back squarely. A jammed or misaligned turntable causes uneven heating and sometimes trips a safety shutoff.
- 4
Never attempt internal repairs yourself
Microwave capacitors store a lethal electrical charge even when the unit is unplugged. Do not open the cabinet under any circumstances — this is a job for a trained technician with the right discharge tools.
- 5
Schedule service for sparking, burning smells, or a dead display
Sparking inside the cavity, a burning smell, or a completely dark display all require professional diagnosis. A running microwave with a fault can worsen quickly.

Repair or Replace Your Microwave?
A well-maintained microwave typically lasts 9–12 years. Use this guide to make the right call.
- • Repair cost is under 50% of a comparable new unit
- • Appliance is under 7 years old
- • First major repair — no pattern of failures
- • Repair cost exceeds 50% of replacement
- • Appliance is past its expected lifespan (9–12 years)
- • Second or third major repair in a short period
- • Parts discontinued or no longer available
Our honest rule: Built-in and over-the-range microwaves under 8 years old are worth repairing if cost is under 50% of replacement. The cabinetry fit of a built-in unit alone justifies repair over a costly tearout and reinstall.
Not sure? We'll give you a straight answer — no pressure, no upsell. (571) 571-1664
