Common Microwave Problems We Fix
From high-voltage component failures to simple door switch issues, we diagnose the actual fault before recommending any repair.
Magnetron Diagnosis & Replacement
The magnetron is the high-voltage tube that generates microwave energy. When it fails, you get no heat. We test magnetron output safely and replace with a matched unit when needed — restoring full heating power.
High-Voltage Diode & Capacitor
A failed high-voltage diode causes a loud humming and no heat — often misdiagnosed as a magnetron failure. We test the full high-voltage circuit (capacitor, diode, transformer) before replacing any component.
Door Latch & Interlock Switch Repair
Most microwaves have three door interlock switches in series — if any one fails, the microwave won't run. Sparking or a microwave that stops mid-cycle can also trace to a failed door switch. We replace the correct switch and verify all three are functioning.
Turntable Motor & Coupler
A microwave that heats unevenly or where the tray no longer rotates usually has a failed turntable motor, a cracked plastic coupler, or a broken guide ring. These are quick, affordable repairs that restore even heating.
Control Panel & Touchpad
Buttons that don't respond, a display that goes blank, or a panel that only partially works indicate a failed touchpad membrane or control board. We source replacement panels for major brands and restore full function.
Honest Repair vs. Replace Guidance
Microwave repair is only worthwhile if cost-effective. Wade will tell you the straight answer — if a magnetron replacement costs more than half the price of a new unit, replacement is likely the smarter move. You'll always get an honest recommendation.

Microwave Repair FAQ
Why is my microwave running but not heating?
This is the most common microwave complaint. The three most likely causes are a failed high-voltage diode, a failed magnetron, or a failed capacitor. The diode is the cheapest fix and often mimics magnetron failure symptoms — specifically a loud humming during the cook cycle. We test all three components in sequence so you only pay for what's actually broken. In some cases a blown thermal cutout (fuse) is also the culprit and is a very inexpensive repair.
Is a sparking microwave dangerous?
Yes — stop using it immediately. Sparking (arcing) inside a microwave can be caused by metallic residue on the interior walls, a damaged waveguide cover, or a failing stirrer fan, but it can also indicate a deteriorating magnetron. Continued use risks fire and can damage the magnetron beyond economic repair. Call us to diagnose the cause before it escalates.
Why won't my microwave start even though the display works?
If the clock and keypad light up but pressing Start does nothing, the most likely culprits are a failed door interlock switch or a failed thermal cutout fuse. Microwaves have 2-3 door switches wired in series — if any one fails open, the unit is electrically dead even though the display draws power from a separate low-voltage circuit. This is usually a quick, inexpensive repair.
How much does microwave repair cost in Forney?
Simple repairs like a door switch, turntable motor, or thermal fuse typically run $75 to $150. Magnetron or control board replacements can range $150 to $300. We always quote before starting work and help you weigh repair cost against replacement cost — especially important on high-end over-the-range models where installation labor makes replacement expensive.
