Likely causes
When we get a call about a microwave not heating but turntable spins, these are the things our technicians check first — roughly in the order of how often each one turns out to be the answer:
- Failed magnetron, the component that actually produces the microwave energy
- Failed high-voltage diode or capacitor in the power circuit
- High-voltage transformer failure
- Door interlock switch out of sequence, cutting the high-voltage circuit
- Blown line fuse following an interlock or high-voltage fault
How we fix it
We diagnose before we quote. That means testing the actual components involved — motors, switches, sensors, valves, and controls — instead of replacing parts in sequence and billing you for the guesses. Once we know what failed, you get the price before we touch anything.
Most microwave repairs of this kind are completed in a single visit, because the parts that cause them are the parts we stock on the van. If yours needs something ordered, we tell you the real timeline up front.
