Microwave repair — especially built-in and over-the-range units
For a countertop microwave, replacement is often the sensible choice. But for a built-in, over-the-range or microwave-wall-oven-combo unit — where a new one is expensive and has to match your kitchen — repair is frequently the smart move. Our factory-trained technicians diagnose the real fault safely (a microwave's high-voltage capacitor holds a dangerous charge even unplugged) and repair it with genuine parts.
The microwave problems we fix most
A microwave that runs but won't heat is the most common call, and it's usually a failed magnetron, high-voltage diode or capacitor. A unit that's completely dead points to a door interlock switch, a blown fuse or the control board. Turntable, keypad, and over-the-range vent-fan and light faults round out the repairs we see on built-in units.
- Runs but doesn't heat the food
- Completely dead, or blowing fuses
- Sparking or arcing inside
- Keypad or control-panel not responding
- Over-the-range vent fan or light not working
Built-in and over-the-range, every brand
We repair Samsung, LG, GE, Whirlpool, KitchenAid, Bosch and more — with a focus on the built-in, over-the-range and combo units where replacement is costly and disruptive. We stock genuine magnetrons, diodes, switches and boards, and we handle the high-voltage side safely.
Repair or replace? An honest recommendation
We'll be candid: a basic countertop microwave usually isn't worth a service call — a new one costs about the same. But for a built-in or over-the-range unit, a magnetron or board repair is typically a fraction of replacement, and it saves you matching a new unit to your cabinetry. We'll tell you which situation you're in before any work.
What to expect when we come out
We diagnose the fault, safely discharge the high-voltage capacitor, give you a written quote, and repair with genuine OEM parts. Every microwave repair we perform is backed by our 6-month parts-and-labor warranty.

Frequently asked questions
My microwave runs but does not heat food. Can it be fixed?
Yes — no-heat is usually a failed magnetron, high-voltage diode or capacitor. These are dangerous to test without training because the capacitor holds a charge, so it is genuinely a job for a technician. For built-in units the repair is well worth it.
Is it worth repairing an over-the-range microwave?
Usually yes. Because it is fitted to your cabinetry and matched to your range, replacement is costly and disruptive. A targeted component repair is typically far more economical.
Sparking inside the microwave — is it safe to use?
Stop using it. Arcing is usually a burned waveguide cover or damaged cavity surface and will get worse. We can repair it quickly and safely.
My microwave runs but doesn't heat — worth fixing?
For a built-in or over-the-range unit, usually yes — it's typically a failed magnetron or diode, which costs far less than replacing an expensive fitted microwave. For a basic countertop model, a new one often costs about the same, and we'll tell you honestly.
Is it safe to repair a microwave yourself?
No — a microwave's high-voltage capacitor stores a dangerous charge even when unplugged. It's genuinely one to leave to a trained technician who can discharge it safely.
