A microwave looks simple from the outside but contains some of the highest-voltage circuitry in any home appliance — the magnetron runs on 4,000 volts. That's why we strongly recommend you do not attempt repairs yourself. The capacitors store a lethal charge even after the oven is unplugged.

Common faults — and what they mean

The good news: 80% of microwave failures fall into just six categories, and almost all are repairable for less than the cost of a new oven.

What we cover

Solo, grill, and convection microwaves from every brand. We handle magnetron replacement, high-voltage capacitor swaps, transformer faults, control panel rebuilds, door interlock switches, turntable motors and couplings, and convection element issues.
