When the microwave quits, dinner plans quit with it. Most homes lean on it every single day, so FM Appliances treats these as quick turnaround jobs and aims to have yours running before we leave.
Spinning but not warming, sparking inside, a dead keypad, a door that won't latch, or a unit that trips the breaker we've seen it all. Whether it's a countertop model, an over-the-range combo, a built-in wall unit, or a slide-out drawer, the fix usually comes down to a handful of parts we already keep stocked: magnetrons, diodes, capacitors, interlock switches, control boards, and turntable motors.
Here's the part people don't realize the capacitor inside a microwave stores a serious jolt of electricity long after it's unplugged. That's exactly why this isn't a job for a screwdriver and a YouTube video. Our techs are trained to discharge and handle it safely, every time.
You'll get a real diagnosis and a firm number before any work starts. No meter running, no surprise markup on parts, no upsell. And if the smart move is to replace rather than repair, we'll say so plainly instead of billing you for a losing fight.
Serving you Monday through Saturday, 8 AM to 6 PM.

Most microwave failures give you warning first. Call us when you notice any of these:
Not heating
Sparks or burning smell
Turntable not spinning
Strange noises
Microwave won't start
Buttons not responding
Door won't latch properly
Display not working
The magnetron is the part that actually generates heat, and when it fails your microwave still runs but leaves food cold. We test the magnetron, high-voltage diode, and capacitor, then replace whatever is drawing the unit down so it heats evenly again instead of just spinning.
Sparks inside the cavity usually mean a burnt waveguide cover, a failing diode, or damage to the interior walls. Left alone it gets worse fast and can destroy the magnetron. We find the source, replace the damaged parts, and make sure the inside is safe to run again.
A plate that won't turn leaves food half-cooked and unevenly heated. The cause is almost always a worn turntable motor, a stripped drive coupler, or a broken roller guide. We pinpoint which one and restore smooth, quiet rotation.
Grinding, buzzing, or rattling points to a tired cooling fan, a failing motor, or a loose internal part knocking around. We track down the noise at its source and replace the worn component before it takes out something more expensive.
A dead microwave can come from a blown thermal fuse, a faulty door interlock switch, a bad control board, or a power supply fault. We run a full electrical diagnostic to find exactly where the circuit breaks and get it powering up reliably.
When the keypad ignores you or only some buttons respond, the membrane switch or control panel is usually failing. We repair or replace unresponsive touchpads and control panels so every setting works the way it should.

It depends on the unit. For built-in, over-the-range, and higher-end countertop microwaves, repair is almost always the smarter, cheaper choice compared to buying new. For an older basic countertop model, replacement sometimes makes more sense. We'll tell you honestly which way saves you money instead of pushing an unnecessary repair.
A microwave that runs but won't heat usually has a failed magnetron, high-voltage diode, or capacitor. These are the components that actually produce the heat. This is one of the most common microwave problems we fix in Charlotte, and in most cases we finish it in a single visit with parts already on the truck.
No, microwaves are one of the most dangerous appliances for DIY repair. The high-voltage capacitor can hold a lethal electrical charge even after the unit is unplugged. Our technicians are trained to discharge and handle these components safely. For your safety, always leave microwave repair to a professional.
Yes. We service every major type — countertop, over-the-range, built-in wall units, and microwave-drawer models. Over-the-range and built-in units often involve extra wiring, venting, and mounting, and our technicians are experienced with all of them across the Charlotte Metro.
Most microwave repairs are completed the same day, often on the first visit. Because we stock the most common replacement parts magnetrons, diodes, capacitors, door switches, and control boards — on the truck, you usually avoid the week-long wait for a return trip.
Sparking or a burning smell is usually caused by a burnt waveguide cover, a failing diode, or damage inside the cavity. It's not something to ignore it can quickly ruin the magnetron and become a fire risk. Stop using the microwave and call us to inspect it as soon as possible.
