Microwave Repair Service

The Light’s On. The Plate’s Spinning. But Your Food Stays Cold.
Your microwave stopped heating. The plate still spins, the light comes on, but your food sits there cold. That’s our most common call in Oakland by a wide margin.
Loud humming or buzzing during operation points to a failing capacitor or a worn diode. Microwaves always make some noise, so that part’s normal. But if the sound changed recently or got noticeably worse, something’s wearing out. Our technicians can test every low and high-voltage component on site and tell you exactly what’s going on before any work starts.
We back every repair with a money-back guarantee. If we can’t fix it, you don’t pay. That takes the guesswork out of the decision entirely.
