Microwave repair in San Francisco
A microwave that sparks, won't heat, or has a turntable that's stopped turning is more than an annoyance, sparking can be a safety issue. We repair built-in, over-the-range, and drawer-style microwaves across San Francisco with same-day appointments.
Signs your microwave needs a repair
- Sparks or flashes visible inside the cavity
- The unit runs and hums but food stays cold
- The turntable doesn't rotate or grinds when it does
- The keypad is unresponsive or the display is blank
- The door doesn't latch or the microwave won't start
Common causes we find
Sparking almost always comes from a damaged waveguide cover, metal touching the cavity wall, or a worn stirrer blade, and it's a safety issue worth addressing right away. When the microwave runs but doesn't heat, a failed magnetron, a blown high-voltage diode, or a faulty door switch are the usual suspects. A turntable that won't turn is often just a worn drive motor or a misaligned support ring, a quick and affordable fix.

Why is my microwave sparking inside?
Sparking usually comes from a damaged waveguide cover, metal touching the cavity wall, or a worn stirrer blade. Stop using the microwave immediately and have it inspected.
