Microwave Repair
A microwave that hums without heating, trips a breaker or rattles the turntable is usually a sign that something inside has changed. Microwaves hold high-voltage parts, so the safest move is to stop using the unit and let a technician take a look.
US In Home Services takes in-home microwave repair requests for countertop and over-the-range units, working from Memphis, Tennessee with communities across the South, Southeast and Midwest. Call (800) 779-3579 or use our online quote form.
Common Signs You Need Microwave Repair
If any of these sound familiar, an in-home assessment can help find the cause.
Runs but doesn't heat
The turntable spins and the light is on, but the food stays cold. Magnetron, diode or capacitor issues can produce this.
Sparks or arcing inside
You see flashes or notice a burning smell. Stop using the microwave right away and have it assessed.
Trips the breaker
The circuit trips as soon as the microwave starts. An electrical fault inside the unit may be responsible.
Buttons or display unresponsive
The keypad does not respond or the display stays blank. Control panel and touch membrane faults are common.
Turntable or fan not moving
The plate sits still, or the familiar sound of the fan is missing. Motor and drive parts may need testing.
Door won't latch properly
The door feels loose or the unit refuses to start at all. Safety interlock switches may be involved.
What Can Cause These Problems
The exact cause depends on the model and the symptoms. Common possibilities include:
A worn magnetron may stop the unit from producing heat even though everything else runs.
A loose or worn door interlock switch may prevent the microwave from starting.
A failing diode or capacitor can interrupt the high-voltage circuit.
A control board or touch panel that is failing may leave the buttons unresponsive.
Metal trim, foil or a damaged interior coating can cause arcing and sparks.

Quick Checks Before You Call
Stop using the microwave if it sparks, smells like burning or trips the breaker. Unplug it only if the cord is easy to reach without moving anything heavy.
Check that the turntable ring and plate are seated correctly and that nothing metal is sitting inside the cavity.
Wipe the interior with a damp cloth and confirm the door closes fully, but never remove the outer cover or reach into the cabinet.
Microwave Repair FAQs
Is it safe to keep using a microwave that doesn't heat?
It is better to stop using it. High-voltage parts may still be energized even when the food stays cold, so a technician should assess the unit first.
Can an over-the-range microwave be repaired in place?
In many cases the unit can be assessed where it is mounted. If it needs to come down, the technician will explain that before any work starts.
Why does my microwave trip the breaker?
That can point to a fault inside the unit or to a circuit shared with other appliances. Either way, stop using it until it has been checked.
Which brands do you handle?
We take requests for GE, Whirlpool, Samsung, LG, Frigidaire, Kenmore, Amana, Maytag, KitchenAid, Haier, Hisense, Midea, Hotpoint, Dacor and Electrolux.
Is it worth repairing a microwave oven instead of replacing it?
Often it is, but it depends on the age of the unit, the part involved and how the rest of it is holding up. Over-the-range models also carry the cost and work of removal and reinstallation, which is why some people ask about repair first. A technician can explain the findings and the options for your unit so you can decide.
Can a microwave that sparks or smells like burning be repaired?
Sometimes, yes. Stop using it as soon as you see sparks or smell burning. Arcing can come from metal trim, foil or a damaged interior coating, and it can also come from a part inside the unit. Whether it can be repaired depends on what the technician finds, so the unit has to be looked at before anyone can say.
