How much does microwave repair cost?#
Microwave repairs run from about $85 to $450, with a typical repair near $190. A door switch or diode sits at the low end, while a magnetron or control board sits at the top. Because a new countertop microwave can cost as little as $150 to $600, repair only clearly pays off on built-in and over-the-range models — and that is not a hedge, it is the whole decision. A countertop unit is competing against a replacement that starts at the bottom of the repair band; a built-in is competing against a replacement plus the installation that goes with it. The same quote therefore means opposite things in two kitchens, and the table below is where that line actually falls for the part you were quoted.
The part you were quoted, against how your microwave is mounted#
Find the part on your estimate, then read the column for your installation. A countertop unit is judged against $150 to $600 for a new one; an over-the-range or built-in unit is judged against that plus a fitting job, which is why the same number changes sides.
| Part quoted | Countertop | Over-the-range or built-in |
|---|---|---|
| Magnetron at $180-$400 | No, in almost every case. The repair meets or passes the price of a new countertop unit | Yes. Well under a replacement once installation is counted |
| Control board at $180-$450 | No. The most expensive repair against the cheapest replacement | Yes on a younger unit, weigh it on an older one — this is the one that can still reach half |
| Capacitor at $115-$220 | Borderline. Compare against the actual price of the model you would buy | Yes, comfortably |
| Diode at $90-$175 | Often yes, at the bottom of that range. It is one of the cheaper high-voltage faults | Yes |
| Turntable motor at $95-$150 | Yes if you like the unit; the oven still heats meanwhile | Yes. A minor repair on a unit that is expensive to swap |
| Door switch at $85-$135 | Yes. The cheapest repair on the list and it restores a unit that will not start | Yes |
| "No heat", part not yet named | Get the diagnosis. It spans a diode at the bottom to a magnetron at the top | Get the diagnosis. Same spread, and it decides the answer here too |
| Any part, and the door is damaged or does not close square | Stop. This is a safety fault first | Stop. A door that does not seal is the one microwave fault nobody should live with |
One thing that is true in both columns: the high-voltage repairs — magnetron, capacitor, diode — are not DIY work at any price. The capacitor inside a microwave holds a lethal charge after the unit is unplugged, and discharging it safely is a trained step, not a careful one. That is part of what the labor on those three lines is buying.
Denominator: every figure above is one of this page's own — an $85 to $450 repair band with a $190 typical figure, the six per-part ranges in its own breakdown, and $150 to $600 for a new countertop microwave. One appliance and its own part list, not a survey across brands or regions, and the replacement figure deliberately covers countertop units only: an over-the-range or built-in replacement carries a fitting cost this page does not price, which is exactly why the two columns above reach opposite answers.

What drives microwave repair costs#
The failed part sets most of the price, but the microwave type sets the stakes. A high-voltage repair — magnetron, capacitor, or diode — carries a pricier part and demands a technician who can safely discharge the circuit. A built-in or over-the-range unit also adds labor because it must be pulled from the cabinet or wall. On a basic countertop model the low replacement price is itself a cost driver, since it caps how much a repair is worth.
Microwave repair cost by part
| Part replaced | Typical cost (parts + labor) | Common signs |
|---|---|---|
| Magnetron | $180–$400 | the unit runs but food stays cold |
| Control board | $180–$450 | a dead panel, unresponsive buttons, or cycles that quit partway |
| Capacitor | $115–$220 | a loud hum, a blown fuse, or no heat |
| Diode | $90–$175 | sparking, a buzz, or no heat |
| Turntable motor | $95–$150 | a tray that will not turn while the unit still heats |
| Door switch | $85–$135 | a unit that will not start or runs with the door open |
Common microwave repairs and what they signal#
Microwave symptoms sort quickly. Running but not heating points to the magnetron, diode, or capacitor; a dead unit that will not start is usually a blown door switch; a plate that will not spin is the turntable motor. Sparking or arcing inside is a separate issue our troubleshooting guides cover. Because several of these involve high voltage, the symptom-to-cost table below is where to start before deciding whether to open anything.
Common microwave problems and what they cost to fix
| Symptom | Most likely repair | Typical cost |
|---|---|---|
| No heat / not warming food | Magnetron | $180–$400 |
| Sparking inside the cavity | Diode | $90–$175 |
| Dead / no power | Control board | $180–$450 |
| Turntable not spinning | Turntable motor | $95–$150 |
| Runs with the door open / will not start | Door switch | $85–$135 |
| Loud humming or buzzing | Capacitor | $115–$220 |
Safety First — Know the Risks
Microwave capacitors store lethal voltage (4,000V+) even when unplugged. This is the single most dangerous DIY appliance repair. Our techs are licensed and insured — let them handle the risk.

Is it worth repairing your microwave?#
This is the one appliance where replacement often wins. A new countertop microwave costs just $150 to $600, so a magnetron repair near the top of the $85 to $450 range can approach the price of a new unit. For a plug-in microwave, replace it once the quote passes half the cost of a new one. For a built-in or over-the-range model — where replacement means matching a cabinet opening — repair is usually still the economical choice.
Repair or replace your microwave?
| If the repair runs… | A new unit, installed, runs… | Usually the smart move |

| $85–$190 (typical) | $150–$600 | Repair |
| toward $450 or more (major) | $150–$600 | Weigh replacement |
Microwave repair cost: frequently asked questions#
How much does it cost to repair a microwave on average?#
A microwave repair averages about $190, with a range of $85 to $450. Low-cost fixes like a door switch at $85 to $135 sit at the bottom; a magnetron at $180 to $400 or a control board at $180 to $450 sits at the top.
What is the most expensive microwave repair?#
The control board at $180 to $450 and the magnetron at $180 to $400 are the most expensive common microwave repairs. Both pair a costly part with the care needed to work around the high-voltage circuit.
Is it cheaper to repair or replace a microwave?#
For a countertop microwave, replacing is often cheaper — a new one is only $150 to $600, close to a major repair. For a built-in or over-the-range unit tied to your cabinetry, repair usually still beats replacement.
Why do microwave repair quotes vary so much?#
Quotes vary because a cheap door switch at $85 to $135 and an expensive magnetron at $180 to $400 can cause the same "not working" complaint, and built-in models add labor to remove and refit the unit.
Does the brand of my microwave change the repair cost?#
For countertop models brand barely matters given the low replacement price. For built-in and over-the-range units from premium brands, parts and the labor to pull the unit both raise the bill.
How much is a service call for a microwave repair?#
The diagnostic is typically folded into the repair, and EasyBear runs a free diagnostic. A standalone service fee elsewhere is small and usually credited toward the repair, though on a cheap countertop unit it can tip the math toward replacement.
Are parts or labor the bigger cost in a microwave repair?#
On a magnetron, capacitor, or diode job the part is the bigger share. On a door switch or turntable motor the labor and diagnostic time dominate, keeping those repairs near the bottom of the $85 to $450 range.
