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 — the breakdown below shows exactly where that line falls.
What microwave repair typically costs
| Repair scale | Typical cost |
|---|---|
| Minor repair | $85–$190 |
| Typical repair | $190 |
| Major repair | $190–$450 |
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 |
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.
