Know the warning signs
Signs Your Microwave Needs Repair
Because microwaves involve high-voltage components, it's worth calling in a professional rather than opening the case yourself.
Runs But Doesn't Heat
The most common cause is a failed magnetron, diode, or high-voltage capacitor.
Sparking or Arcing Inside
Check for stray metal or foil first. If none is found, the waveguide cover is often damaged and needs replacing.
Turntable Won't Spin
Usually a worn motor or a cracked drive coupler. Food still heats, but unevenly.
Buttons Unresponsive
A worn touch panel membrane or a control board fault. Check for an active child lock first.
Loud Humming Noise
Can point to the diode, magnetron, or cooling fan. Worth having checked before it worsens.
Runs With Door Open
Stop using it immediately. This is a door switch failure and a genuine safety hazard.
Microwaves hold dangerous voltage even when unplugged
The high-voltage capacitor inside a microwave can hold a charge long after it's unplugged. This is one appliance we strongly recommend never opening yourself — leave magnetron, capacitor, and diode repairs to a trained technician.
Every style, every brand
Microwave Types We Repair
From a simple countertop unit to a built-in with an inverter board, our technicians repair every configuration.
What it costs
Microwave Repair Cost Guide
Most microwave repairs in Clairton fall between $50 and $400. Because countertop microwaves are relatively inexpensive to replace, a repair quote near the top of that range is worth comparing against a new unit.
Built-in and over-the-range microwaves are usually worth repairing even at a higher cost, since replacement means matching cabinet cutouts and venting.

Common questions
Microwave Repair FAQs
Why does my microwave run but not heat food? +
This almost always points to a failed magnetron, high-voltage capacitor, or diode. These are internal, high-voltage parts that should only be handled by a trained technician.
Is it safe to keep using a microwave that sparks? +
No. Stop using it right away. Check for stray metal or foil first; if none is found, the waveguide cover likely needs replacing.
How much does microwave repair cost in Clairton? +
Most microwave repairs run between $50 and $400, depending on the part. For countertop units, we'll tell you honestly if replacement makes more sense.
Should I repair or replace my microwave? +
For countertop microwaves, if the repair approaches half the price of a new unit, replacement is often the better value. Built-in units are usually worth repairing due to installation costs.
Is it safe to open my microwave myself? +
No. The high-voltage capacitor can hold a dangerous charge even after the microwave is unplugged. This repair should always be left to a trained technician.
