Why is my microwave not heating?

A failed magnetron, diode, or capacitor is usually the cause. These are internal high-voltage components that should only be serviced by a professional.

Is it safe to use a microwave that sparks?

No — stop using it immediately. Sparking can be caused by a damaged waveguide cover, metal left inside, or a failing magnetron. Call us for a diagnosis.

Do you repair over-the-range microwaves?

Yes, we service countertop, over-the-range, built-in, and drawer-style microwaves from all brands.

Is it worth repairing a microwave?

For basic countertop models under $200, replacement may be cheaper. For built-in or over-the-range units, repair is almost always more cost-effective.

My microwave runs but the turntable doesn't spin.

The turntable motor or coupler is likely worn out. This is a quick, inexpensive repair — usually done in under an hour.

Microwave Problems Explained — What Is Actually Wrong

Failed Magnetron

The magnetron generates the microwaves that heat your food. When it fails, the microwave runs normally — the light works, the turntable spins — but food stays cold. Magnetron replacement is the most common microwave repair and restores full heating power.

Defective Door Switch

Microwaves have multiple safety switches in the door latch. If any switch fails, the microwave will not run at all — this is a safety feature to prevent radiation leakage. Door switch replacement is quick and inexpensive, and we test all switches during every microwave service call.

Damaged Waveguide Cover

The waveguide cover is a small panel inside the microwave cavity that directs microwave energy. When food splatter burns through it, you will see sparking. Continuing to use the microwave with a damaged waveguide can destroy the magnetron. We replace the cover and clean the cavity.

Faulty Diode or Capacitor

The high-voltage diode and capacitor work together to power the magnetron. When either fails, the microwave produces no heat or makes a loud buzzing sound. These are high-voltage components that should never be serviced at home — our technicians safely diagnose and replace them.

How Much Does Microwave Repair Cost in South Florida?

$75–$200typical repair cost

Microwave repairs are among the most affordable appliance fixes. Door switch replacement runs $75–$125. Turntable motor replacement costs $85–$150. Magnetron replacement is the priciest common repair at $150–$250. For countertop microwaves under $150, replacement may make more sense than repair. For built-in or over-the-range units ($400–$800+), repair is almost always the right call.
