How Much Do Microwave Repairs Cost in 2025?

This article was updated using automation technology and thoroughly reviewed for accuracy by HomeAdvisor Editor Ryan Noonan.

Most microwaves need a little TLC every seven to 10 years. The average range for microwave repairs is between $100 and $200. You can spend as little as $50 or as much as $500, but the average cost of a microwave repair is $150. 

Your final bill depends on the type of issue, the nature of the problem, and the parts that need to be replaced. Hiring a professional to fix your microwave ensures an accurate diagnosis of the problem and a safe, effective repair.

Microwave Repair Cost Factors

Your microwave repair total depends on several factors, including parts and labor. Here’s a closer look at the cost drivers that influence your final price.

Cost by Part

Because a microwave is packed with moving parts, the exact repair—and its price—hinges on which component has stopped working

Magnetron

The magnetron is the heart of your microwave. Swapping it out for a replacement costs an average of $100 to $200. 

Diode 

Replacing a diode runs $55 to $130, parts and labor included. This semiconductor can fail over time, leading to sparks, loud hums, or a burning smell. If you’re already swapping the magnetron, ask your appliance repair professional to change the diode while the unit is open.

Control Board

When the microwave runs but won’t heat, keeps humming with the door shut, or quits seconds after you press Start, the control board is usually the culprit. Swapping it out costs $100 to $300.

Turntable

A replacement glass tray costs $50 to $230 and is a true plug‑and‑play fix—just match the size to your model and set it in place.

Turntable Motor

Expect $50 to $100 for a new motor. If the plate won’t spin and the door switch checks out, the motor is likely toast. First, make sure the glass tray and roller guide aren’t damaged—those quick fixes cost less.

Door Assembly

A cracked glass door or a latch that refuses to budge means you’ll need a full door assembly, which costs between $200 and $500, depending on brand. 

Touchpad

A finicky touchpad costs $100 to $300 to fix. Clues include a microwave that won’t start, keeps humming after time’s up, or shuts down mid‑cycle. Sometimes a quick control‑board tweak solves it; other times you’ll need a brand‑new panel.

Door Switch

A bad door switch costs between $50 and $100. Sometimes a quick adjustment does the trick; if not, a new switch is an easy and low-cost installation.

Fuse

Plan on spending an average of $75 to $200 for a pro to swap a blown fuse, a common problem as electronics age.

Fan

Loud rattles or a grimy, sluggish vent point to a worn‑out exhaust fan motor. Replacing it costs $75 to $200.

Transformer

Running but not heating, sparking, or even smoking can signal a failing transformer. A new one costs an average of $100 to $200.

Cost by Issue

Not sure what’s wrong? Start with the symptom you’re seeing and work backward.

Microwave Running With the Door Open

A microwave that runs with the door open almost always has a bad door switch. This is an urgent fix and you’ll spend an average of $50 to $100 for the repair. Unplug the unit and call a pro before you use it again.

Sparks Inside Microwave

See sparks? Hit Stop, unplug the microwave, and make sure no stray metal or foil was left inside.

If there’s no metal inside, then you likely need to replace a faulty diode. This will cost an average of $55 to $130, including both the part and the cost to hire an electrician or appliance repair pro.

Microwave Not Spinning

If the plate refuses to spin, expect $50 to $230 for either a motor, roller guide, or tray swap.

Microwave Type

Built‑in and over‑the‑range units usually cost more to fix than easy‑to‑reach countertop models. Accessibility is the primary driver—countertop units are quicker and cheaper for technicians to reach and service.

Labor

Pros charge $50 to $150 an hour for appliance work. Because most microwave fixes are quick, you’ll likely pay the minimum one‑hour fee and be done.

Repair vs. Replacement

Whether you should repair or replace your microwave will depend on several factors. One is the severity of the repair that's required. If you have a hunch that it's an easier fix—like a diode replacement, door switch repair, a new handle or turntable, or the like—then it'll likely be more cost-effective to fix your microwave than to buy a new one.

Deciding between a repair and a replacement comes down to the size of the fix. Quick jobs—diodes, door switches, handles, or trays—almost always cost less than shopping for a new unit.

Think about what you paid for the unit. Luxury or built‑in models are often worth fixing, while a bargain countertop microwave might be cheaper to replace, especially if the magnetron or touchpad goes out.

If you’re unsure, it’s a good idea to hire a pro to get a diagnosis of the issue.

Budgeting for Microwave Repairs

Looking to trim your repair bill? Try these budget‑friendly moves:

• Rule out easy fixes first—a clogged filter, blown fuse, or tripped outlet—before you book a service call.

• While the tech is there, ask for maintenance tips that help prevent future breakdowns.

• Wipe down the interior regularly so grease and food splatter don’t clog vents or fans.

• If a pro is already fixing another appliance, have them inspect the microwave, too; combining jobs usually costs less than a separate visit.

DIY vs. Hiring a Pro

Microwave repairs are best left to professional appliance technicians due to the complex systems and electrical components. It can be hard to properly diagnose the part that needs repair on your own, and attempting to replace electrical parts without proper training is dangerous. For efficient and safe repairs, hire a local appliance repair professional to fix your microwave.
