Materials

Repairing a microwave isn’t always just about labor; certain parts might need to be swapped out as well. Prices for these components differ: minor replacements, such as a lightbulb, can start at about $45, whereas major parts like a new door may cost as much as $340.

Labor

Technicians usually bill between $90 and $150 per hour. Taking your microwave to a repair shop can save money, but it may mean waiting longer. Because repairs are completed in the order they arrive, it can take several days—or even up to a week—before your appliance is fully operational again.

Repair Cost by Type of Microwave

How much it costs to repair a microwave often hinges on its style and how it’s installed. Countertop microwaves are usually the easiest and least expensive to repair, while built-in or over-the-range models can be pricier because of their more complicated setup.

Microwave Type	Cost to Repair
Countertop	$90–$390
Built-in	$90–$540
Over-the-range	$90–$540

Countertop

Fixing a countertop microwave usually costs between $90 and $390. These models are common and easy to work with, so technicians can often complete repairs more quickly and with less hassle.

Built-In

Repairing a built-in microwave typically ranges from $90 to $540. Costs are higher because these units are custom-installed and harder to reach, and the extra time required for servicing can raise labor charges.

Over-the-Range

Over-the-range microwaves usually cost between $90 and $540 to repair. Like built-in units, their placement above the stove and within cabinets makes them harder to reach, which can lengthen the time needed for repairs.

Magnetron Replacement

The magnetron is the part that produces the heat in a microwave, so if it fails, your food won’t cook correctly. Replacing a broken magnetron typically costs between $140 and $240. Because labor makes up roughly half of this cost, installing the part yourself can save money.

Diode Replacement

At Appliance SD Repair, swapping out a microwave diode usually runs from $95 to $170. While the part itself is inexpensive, a faulty diode can cause sparks. Installing it correctly takes specialized skills, so it’s recommended to hire a licensed technician, whose hourly rate generally falls between $90 and $140.

Microwave Fuse Replacement

Replacing a microwave fuse generally costs around $50 to $55. Although the repair itself is simple, having a professional handle it can increase the total price to roughly $90 to $140.

Microwave Fan Repair

Fixing a faulty microwave fan usually falls in the $115 to $240 range. The fan’s role is to move air and vent it properly. For built-in or over-the-range microwaves, reaching the fan can be more difficult, which may increase the overall repair price.

Touch Panel Repair or Replacement

Replacing a malfunctioning microwave touch panel generally costs between $140 and $340. Simple repairs to the control board can keep the price lower, whereas installing an entirely new panel tends to be more expensive.

Transformer Repair

Repairing a microwave transformer usually ranges from $140 to $240. Simple fixes are less expensive, but replacing the entire transformer can raise the cost. If the microwave is hard to reach, extra labor may add to the total price.

Door Switch Repair

Fixing a broken microwave door switch generally costs $90 to $140. Sometimes, a small adjustment can fix the problem without extra charges. If the switch needs to be completely replaced, the main cost comes from the new part itself. Luckily, replacing a door switch is usually an easy task you can do yourself.

Microwave Filter Replacement

Replacing or repairing a microwave filter usually ranges from $90 to $165, depending on its type and condition. Sometimes a deep cleaning is enough, but other times the filter needs a complete swap. Filters for over-the-range microwaves often cost more than those for countertop units, and prices can also differ by brand, with some manufacturer parts being pricier than generic options.

Microwave Door Glass Replacement

Fixing a microwave’s glass door usually falls between $190 and $440. The glass alone often accounts for $140 to $340 of the total cost. Bigger or premium-quality doors generally cost more than smaller or standard options.

Glass Plate Replacement

Replacing a microwave turntable and its motor usually costs between $90 and $270. If the plate stops spinning, the motor is often the culprit, whereas a cracked glass turntable only needs the plate itself replaced. Swapping out the glass turntable typically runs $65 to $170, while a new turntable motor costs around $55 to $140.

Door Replacement

Changing a microwave door tends to be one of the pricier repairs, usually costing between $240 and $540. While fitting the door is generally straightforward, the majority of the cost comes from the price of the door itself.
