Did You Know?
Microwave repair costs $100 to $300 total in 2026 for most US households: a service call runs $45 to $100, a magnetron is $100 to $300, and a door switch is $120 to $180. Countertop units rarely justify repair above $80, while over-the-range and built-in models usually do.
Frequently Asked Questions
QHow much does it cost to repair a microwave in 2026?
Most US households pay $100 to $300 total to repair a microwave in 2026, with an average near $175. That figure bundles a service-call fee of $45 to $100 with parts and labor. Countertop repairs are cheapest at $80 to $180, while over-the-range and built-in units run $130 to $330 because cabinetry access adds labor time. The exact price depends on the failed part: a magnetron, door switch, or control board each sits in a different cost band.
- Typical all-in repair: $100 to $300 total
- Service-call fee: $45 to $100 (often credited toward the repair)
- Labor: $50 to $125 per hour
- Countertop repair: $80 to $180
- Over-the-range / built-in repair: $130 to $330
| Repair Scenario | Typical Cost | Worth Repairing? |
|---|---|---|
| Countertop, minor fault | $80 to $150 | Usually replace |
| Over-the-range magnetron | $150 to $300 | Usually repair |
| Built-in control board | $200 to $500 | Often repair |
| Door switch / latch | $120 to $180 | Repair |
QHow much does it cost to replace a microwave magnetron?
Replacing the magnetron — the part that actually generates the microwaves — costs $100 to $300 installed, and it is the most common fix for a microwave that runs but will not heat. The part itself is $40 to $150, and the rest is labor plus the service call. Because a no-heat symptom almost always traces to the magnetron, high-voltage diode, or capacitor, this is the repair most likely to make financial sense on an over-the-range or built-in unit.
- Magnetron replacement: $100 to $300 installed
- Magnetron part alone: $40 to $150
- Common companion parts: high-voltage diode and capacitor ($10 to $40 each)
- Typical symptom: unit runs and lights up but food stays cold
- Not a DIY job — the capacitor holds a lethal charge even unplugged
QIs it worth repairing a microwave or should I replace it?
It depends almost entirely on the type. A countertop microwave rarely justifies repair: a new one starts near $100, so any quote above $80 usually means you should replace it. Over-the-range and built-in units are the opposite — a new OTR is $250 to $500 plus $100 to $200 to install, and a built-in can top $1,000, so a $150 to $300 repair is the smart call. A good rule of thumb is the 50% rule: if the repair costs more than half the price of a comparable new unit, replace it.
- Countertop: replace if repair tops $80 (new unit from $100)
- Over-the-range: repair usually wins (new OTR $250 to $500 plus install)
- Built-in: repair almost always wins (replacement can exceed $1,000)
- 50% rule: replace when repair exceeds half the new-unit price
- Units 8+ years old lean toward replacement regardless of type
| Microwave Type | New Unit Cost | Repair Break-Even |
|---|---|---|
| Countertop | $50 to $500 | Replace over ~$80 |
| Over-the-range | $250 to $500 + install | Repair under ~$250 |
| Built-in | $500 to $1,500 + install | Repair under ~$400 |
| Drawer | $800 to $2,000 + install | Repair under ~$500 |
QWhat is the service-call fee for microwave repair?
A microwave repair service call runs $45 to $100 in 2026, and most technicians credit it toward the final bill if you approve the repair. The fee covers the trip and the diagnosis, so you pay it even if you decide not to fix the unit. To avoid paying a diagnostic fee on a microwave that is not worth saving, describe the symptom and the model when you book — many shops will tell you over the phone whether a countertop unit is even worth a visit.
- Service-call / diagnostic fee: $45 to $100
- Usually credited toward the repair if you proceed
- Charged whether or not you approve the fix
- Labor billed on top at $50 to $125 per hour
- Ask for a phone estimate before booking a countertop visit
QWhy do over-the-range and built-in microwaves cost more to repair?
Over-the-range and built-in microwaves cost $50 to $150 more to repair than countertop models because the technician has to dismount and re-mount the unit. An OTR is bolted to the cabinet and ducted to a vent, and a built-in sits inside a trim kit in cabinetry, so simply reaching the parts adds labor time before any repair begins. Countertop units, by contrast, can be carried to a bench, which is why their repairs stay in the $80 to $180 range.
- Countertop: portable, lowest labor, $80 to $180
- Over-the-range: must unbolt and re-vent, $130 to $330
- Built-in: trim-kit and cabinetry removal, $150 to $350+
- Drawer: specialized mechanism, often highest labor
- Access labor is added before the actual part is replaced

Formulas Used
Total microwave repair cost build-up
Total = Service call + Part cost + (Labor rate x Hours) + Access surchargeA microwave repair bill is the service call plus the part, the labor to fit it, and any extra labor to dismount a built-in or over-the-range unit. Start from the part cost, add labor, then layer the access surcharge for installed models.
Where:
Service call= Trip and diagnostic fee of $45 to $100, usually credited toward the repair if you proceedPart cost= Magnetron $40 to $150, door switch $20 to $60, control board $80 to $300, waveguide cover $15 to $50Labor rate x Hours= $50 to $125 per hour, with most repairs taking 1 to 2 hoursAccess surcharge= $50 to $150 extra to unbolt and re-mount over-the-range, built-in, or drawer unitsRepair-vs-replace 50% rule

What Microwave Repair Costs in 2026
A dead microwave is one of those small household failures that forces a quick decision: pay a technician, buy a new unit, or live without it. In 2026, the typical US microwave repair costs $100 to $300 in total, with an average right around $175. That figure bundles three things — a service-call fee, the replacement part, and the labor to fit it — and the spread is wide because a $20 door switch and a $300 control board sit at opposite ends of the same category.
The first number on every bill is the service call. Technicians charge $45 to $100 just to show up and diagnose the problem, and most credit that fee toward the repair if you approve it. Labor then runs $50 to $125 per hour, and most microwave repairs take one to two hours once the unit is open. The part is the variable that swings the total: a no-heat magnetron job and a non-responsive keypad can both be "a microwave repair" yet differ by a hundred dollars or more.
Installation type is the other headline driver, and it is easy to overlook. A countertop microwave can be carried to a bench, so its repairs stay in the $80 to $180 range. An over-the-range or built-in unit has to be unbolted, unvented, and re-mounted before the technician even reaches the failed part, which is why those repairs run $130 to $330. Use the calculator above to land on a figure for your symptom and unit type, then read on to see which fixes are worth paying for.
| Repair Type | Typical Cost | What It Covers | Best For |
|---|---|---|---|
| Service call only | $45 to $100 | Trip and diagnosis | Confirming the fault |
| Countertop repair | $80 to $180 | Part plus bench labor | Freestanding units |
| Over-the-range repair | $130 to $330 | Part, labor, re-mount | OTR units |
| Built-in repair | $150 to $350+ | Part, labor, trim-kit access | Cabinet units |
Almost every technician credits the $45 to $100 service-call fee toward the repair if you proceed — but you pay it even if you walk away, so describe the symptom and model when you book to avoid a diagnostic fee on a unit that is not worth saving.

Repair Costs by Failed Part
Microwaves fail in a handful of predictable ways, and the part that broke determines most of the bill. The single most common repair is the magnetron, the component that generates the microwaves themselves. When a unit runs, lights up, and spins the turntable but leaves food cold, the magnetron — or its companion high-voltage diode and capacitor — is almost always the cause. A magnetron replacement runs $100 to $300 installed, and it is the repair most likely to justify itself on an expensive built-in or over-the-range unit.
Door and switch faults are the next most common, and they are usually cheaper. The interlock switches that tell the microwave the door is shut are a $20 to $60 part, and replacing them runs $120 to $180 with labor. A full door assembly — glass, latch, and hinges — is pricier at $100 to $300 because the part itself costs more. Control-board and keypad failures are the wild card: a touch panel that no longer responds can mean an $80 board on a budget unit or a $300-plus board on a premium built-in, pushing the total toward $500 on high-end models.
Sparking or arcing inside the cavity sounds alarming but is often the cheapest fix of all. The usual culprit is a burnt waveguide cover, a $15 to $50 part, or a worn stirrer. The catch is that diagnosis takes a trained eye, and arcing can also signal a failing magnetron, so the service call earns its keep here. Whatever the symptom, microwave repair is not a safe DIY job: the high-voltage capacitor stores a potentially lethal charge even after the unit is unplugged, which is the main reason these repairs carry a professional labor charge.
| Failed Part | Symptom | Part Cost | Installed Cost |
|---|---|---|---|
| Magnetron | Runs but no heat | $40 to $150 | $100 to $300 |
| Door switch / interlock | Will not start | $20 to $60 | $120 to $180 |
| Control board / keypad | No response to buttons | $80 to $300 | $100 to $500 |
| Waveguide cover | Sparking / arcing | $15 to $50 | $80 to $200 |
| Turntable motor | Plate will not spin | $15 to $40 | $80 to $150 |
Never open a microwave yourself to save labor. The high-voltage capacitor holds a dangerous charge even when the unit is unplugged, and discharging it incorrectly can be fatal. This is the one appliance where the labor fee is also a safety fee.

Repair vs Replace: The Honest Math
The real question is rarely "how much is the repair" but "is the repair worth it," and the answer flips entirely based on the type of microwave you own. The blunt truth on countertop units is that they are usually not worth fixing. A new countertop microwave starts around $100, and many sell for $80 on sale, so once a repair quote crosses $80 you are spending new-unit money to keep an aging one. Unless the unit is nearly new or under warranty, replacing a countertop microwave is the rational move.
Over-the-range and built-in units invert that logic. A new over-the-range microwave costs $250 to $500, plus $100 to $200 to mount and vent it, and a built-in can run $500 to $1,500 before the install kit and labor. Against those numbers, a $150 to $300 repair is clearly the better value, which is why technicians see far more OTR and built-in repairs than countertop ones. The widely used 50% rule captures this neatly: if the repair costs more than half the price of a comparable new unit, replace it; below that line, repair. Drop the threshold toward 40% once a unit passes eight years, since the next failure is rarely far behind.
Age and warranty are the tie-breakers. A unit under three years old is often still covered — check the paperwork before you pay anyone, because the part may be free even if the labor is not. A microwave older than eight years has likely depreciated past the point where a major repair makes sense, regardless of type. And if the failed microwave is part of a larger kitchen project, it can be worth folding the replacement into that work; the kitchen remodel cost calculator puts the appliance line item in context with cabinets and counters, and the appliance repair service cost calculator compares the microwave decision against the other appliances aging alongside it.
| Microwave Type | New Unit + Install | Repair Worth It If | Default Move |
|---|---|---|---|
| Countertop | $50 to $500 | Under ~$80 and near-new | Replace |
| Over-the-range | $350 to $700 | Under ~$250 | Repair |
| Built-in | $600 to $1,700 | Under ~$400 | Repair |
| Drawer | $900 to $2,200 | Under ~$500 | Repair |
Run the 50% rule before you book: if the quote is more than half the price of a comparable new unit, replace it. For a $100 countertop microwave that means almost any paid repair, while for a $1,200 built-in it means nearly any repair is worth doing.

How to Get a Fair Microwave Repair Quote
Because the service call is charged whether or not you proceed, the cheapest way to handle a broken microwave is to triage it before anyone visits. Start by describing the symptom and reading the model number off the inside of the door frame when you call. A good shop will tell you over the phone whether a countertop unit is even worth a visit, and many will give a rough part-and-labor band for an over-the-range or built-in fault before booking, so you are not paying a diagnostic fee to learn you should buy new.
When you do get a written quote, confirm three things: whether the service-call fee is credited toward the repair, whether the part is new or refurbished, and whether the price includes the extra labor to dismount and re-mount an installed unit. A quote that looks cheap can quietly exclude the access labor that an over-the-range or built-in repair always involves, and that gap reappears as a change order once the technician is on site. For installed units, the labor to re-mount is as real a cost as the part itself.
Finally, weigh the repair against your wider home plans. If you are replacing the microwave rather than fixing it, the junk removal service cost calculator prices hauling away the old over-the-range or built-in unit, which is heavier and more awkward than people expect. And if the microwave failure is one of several aging systems, lining it up against bigger-ticket work — using tools like the HVAC install cost calculator — helps you spend the home-maintenance budget where it actually moves the needle rather than on a unit you will replace within a year anyway.
Never choose a repair on headline price alone. A quote that omits the re-mount labor on a built-in unit, or uses a refurbished magnetron with no warranty, can cost more in the end than the slightly higher bid that does the job once and stands behind it.
- 1
Triage by phone first
Read the model number and describe the symptom so the shop can flag a countertop unit that is not worth a paid visit.
- 2
Confirm the service-call credit
Ask whether the $45 to $100 diagnostic fee is applied toward the repair if you proceed.
- 3
Get the part and access in writing
Make sure the quote names the part, says new or refurbished, and includes re-mount labor for OTR or built-in units.
- 4
Apply the 50% rule
Compare the all-in quote to half the price of a comparable new unit before approving the work.
- 5
Check warranty and age
Verify coverage on units under three years old and lean toward replacement on anything past eight.
