With more than 90% of American households relying on microwaves to heat food daily, a broken appliance can be a major inconvenience. When a microwave fails, it is important to get it fixed quickly. While it may be tempting to replace it, a new appliance can be expensive, making repairing one more budget-friendly.

Many things can go wrong with a microwave oven, leaving it unable to cook food properly. From a blown fuse or defective door switch to a burned-out magnetron or faulty transmitter, repair costs average $100 to $200, with most homeowners paying about $150 for the repair or replacement of a magnetron in a countertop unit. You can have your microwave repaired for $50 if the problem is minor, such as a new fuse. Larger repairs cost more, with control board replacements on built-in units costing up to $500.

Microwave Repair Price by Type

Microwaves come in many types, from countertop units that can be moved around to built-in and over-the-range microwaves that are fitted permanently in place. Microwave repairs costs are influenced by the unit type:

Cost to Repair a Countertop, Built-In, and Over-the-Range Microwave

Cost to Repair a Countertop, Built-In, and Over-the-Range Microwave

TypeAverage Repair Costs
Countertop$50 - $350
Built-In$50 - $500
Over-the-Range$50 - $500

Countertop Microwave Repair Prices

Repairs for countertop microwaves cost between $50 and $350 on average. These microwaves are the most common and usually the most affordable. They are highly practical and portable, and you can place them anywhere on your kitchen counters. They tend to be the cheapest microwaves to repair because it is easy for repairmen to move them and reach the parts they need to fix or replace.

Built-in Microwave Repair Prices

Repairs for built-in microwaves average $50 to $500, depending on the problem and amount of work required. These microwaves are built into your kitchen cabinets, giving them a modern and seamless look and saving counter space. This makes repairs more difficult and costly, however, because workers may have to spend more time accessing the parts.

Over-the-Range Microwave Repair Prices

Repairs for over-the-range microwaves cost between $50 and $500. Like built-in microwaves, over-the-range microwaves are fixed in place. They are positioned right above the range and can be a good choice in contemporary kitchens for saving space and enhancing the aesthetic appeal of the room. The repair costs for over-the-range microwaves can be higher because it is harder for workers to get to the back and sides of the unit.

Microwave Repair Cost by Type of Repair

The main factor influencing the cost of your microwave repair is the repair work needed. Microwaves have a wide range of problems, and some are relatively quick and easy to fix. But others are complicated, requiring more work or costly parts. Depending on the issue, parts may either be repaired or replaced with new ones. The table below shows average costs for fixing common microwave components:

Cost to Repair a Microwave Fuse, Door Switch, Filter, Handle, Plate...

Transformer$100 - $300
Touchpad$100 - $300
Control Board$100 - $500
Door Glass$150 - $400
Door$200 - $500

Microwave Fuse Replacement Cost

Fuse replacements for a microwave cost between $50 and $100 on average. This is one of the cheapest and simplest microwave repair jobs. Many appliances have fuses, and over time, it is natural for fuses to wear out or blow. Replacing a blown fuse with a new one should take less than half an hour for most microwaves.

Microwave Door Switch Replacement Cost

Microwave door switch repairs or replacements average $50 to $100. The door switch is a small but important component in the microwave that essentially stops the microwave from functioning when the door is open. Replacement switches are very cheap to obtain and can be fitted in under an hour in most cases.

Microwave Diode Replacement Cost

Microwave diode replacements cost between $50 and $125 on average. The diode is an essential part of the microwave that helps create and receive microwave signals, but it usually wears down over time. You can often notice a faulty diode by the presence of sparks in your microwave. Fortunately, diodes are inexpensive to buy and replace.

Microwave Filter Replacement Cost

Microwave filter repairs range from $50 to $125. Many microwaves come with mesh charcoal filters that trap grease and contaminants, but they become clogged over time. If your filter is dirty, it may simply need cleaning, which can be done cheaply. Or, it might need a full replacement, which may be more costly.

Microwave Handle Replacement Cost

Microwave handle repairs average $75 to $125, depending on the model and cost of the replacement parts. Handles on microwave doors can be made from various materials, and some of the weaker ones may break over time. Part costs can be high for certain brands, but labor costs should not be too high for this job because it is relatively simple to remove a broken handle and fit a new one.

Microwave Plate Replacement Cost

Microwave plate replacements cost between $75 and $150, and this is one of the few microwave repair jobs you can do without the help of a professional. The plate or turntable is a thick sheet of glass that turns inside the microwave to help food heat evenly. If it cracks or shatters, replace it by taking the old one out and placing a new one inside. It does not need to be screwed in, so the job can be done in a matter of seconds. But it is important to get the correct plate for your microwave.

Microwave Fan Replacement Cost

Microwave fan repairs or replacements average $75 to $200. The fan recirculates air from the appliance back into the kitchen or out of the home via a vent if you have your microwave connected to ductwork. When it stops working, the grease, dirt, and contaminants in the air can build up in or around the microwave. Most fan replacements are inexpensive, but they can cost more for built-in or over-the-range units because more labor is required to access the fan.

Magnetron Replacement Cost

Magnetron repairs cost between $100 and $300 on average. The magnetron is one of the most important components of the microwave, transforming the unit’s electrical current into microwave energy. Usually, repairs are not possible for broken magnetrons, and they need to be completely replaced with new ones. Replacing a magnetron can be very dangerous, so it is essential to hire an experienced, certified repairman for the job.

Microwave Transformer Replacement Cost

Transformer repair or replacement for a microwave averages $100 to $300. Transformers play an important role in the functionality of any microwave, working to amplify the power supplied to the appliance to produce enough current to create microwave energy. When a transformer stops working, the microwave will not function correctly or at all. Replacement is dangerous work, so it should always be handled by a professional.

Microwave Touchpad Repair Cost

Microwave touchpad repairs cost between $100 and $300, depending on the make and model. The touchpad is how you interact with the microwave, programming the time and temperature and choosing the settings. Some touchpads are inexpensive to buy and replace, but others with more advanced technology cost more.

Microwave Control Board Replacement Cost

Control board repairs and replacements for microwaves range from $100 to $500. The control board is the center of your microwave, responsible for all the features and functions. A faulty control board may make a microwave completely unusable. In some cases, repairs may be possible, but in others, a full replacement board might be needed. A repairman should diagnose the problem and decide on the best course of action.

Replace Microwave Door Glass

Replacing the door glass in a microwave costs between $150 and $400, depending on the make and model. If the glass has a small crack, the microwave may still work fine because the glass is mostly a cosmetic element. However, many people do not want to look at cracked glass every day, so they prefer to have the panel taken out and a new one fitted in place to make the microwave look brand new.

Microwave Door Replacement Cost

Microwave door replacements average $200 to $500. This is often one of the most expensive repair jobs for a microwave because the part costs can be high for some brands due to the materials used. Replacing the door is not too difficult because the old one can be unscrewed and the new one fitted into position.

If you are not a microwave expert, you might not know exactly which part of your appliance has a problem. You may notice that something is not working correctly, hear a strange sound coming from the microwave, or even see sparks on the inside. All these problems have root causes that can be diagnosed and fixed by an experienced technician. The table below shows common microwave problems and the average repair costs:

Cost to Repair Microwave Still Running With the Door Open, Sparking Inside, Humming With a Closed Door, Not Heating, with Plates not Spinning...

Cost to Repair Microwave Still Running With the Door Open, Sparking Inside, Humming With a Closed Door, Not Heating, with Plates not Spinning...

ProblemAverage Repair Cost (Labor Included)

Humming$50 - $300
Not Heating$50 - $500
Plate Not Spinning$75 - $300
Motor Not Working$100 - $300
Outside Sparks$100 - $500

Microwave Still Running With the Door Open

Fixing a microwave that runs even with the door open costs between $50 and $100. It is dangerous to have a microwave running with the door open, so this problem needs to be fixed quickly. It usually occurs because of a fault with the door switch, which is responsible for stopping the microwave from functioning when the door is open. These switches are inexpensive to replace.

Microwave Sparking Inside

Fixing sparks inside a microwave averages $50 to $125. There are several potential causes of this problem. It is typically a problem with the diode, which is cheap to replace. But it might be because of another component or that you accidentally placed metal in the microwave.

Microwave Humming With a Closed Door

Fixing a humming or noisy microwave ranges from $50 to $300. There are various reasons for a humming microwave. It might be an issue with the diode, magnetron, or the fan, so call in a repairman to find the exact cause and a solution.

Microwave Not Heating

Repairing a microwave that is not heating costs between $50 and $500. The costs for this repair vary, depending on the problem. It might be a diode or door switch issue, which are both easy to fix, but it could also be a problem with a more expensive component like the control board or magnetron.

Microwave Plate Not Spinning

Repairing a microwave when the plate does not spin averages $75 to $300. There are a few causes of this problem. The motor is likely to blame because the motor turns the plate. It could also be an issue with the roller guide, which is the small component that sits under the tray and rotates it smoothly. It could even be an issue with the plate itself, such as damage or cracks, which could require a full plate replacement.

Microwave Motor Not Working

Fixing a microwave with the motor not working ranges from $100 to $300. If the motor in your microwave stops working, the turntable or glass plate on the inside will not rotate, and your food will not evenly cook. Broken motors usually need to be replaced with new ones, but if the problem is small, repairs may be possible.

Microwave Sparking Outside

Repairs for a microwave that sparks on the outside cost between $100 and $500. There are several possible causes. It might be that the door or mesh metallic grid inside the door has become damaged, but it could also be an issue with the wiring. The door may need repairing or replacing, which can be costly.

Labor Costs to Repair a Microwave

Homeowners can make some simple repairs on their own, but in most cases, a professional repair expert ensures that the microwave is fixed properly and safe to use. Professionals have the knowledge and experience to work with all microwave brands and models. Plus, they have quick access to needed parts, which gets your appliance up and running faster. They are also knowledgeable when working with electricity, making the repair safer.

Paying for labor usually costs about $50 to $100 an hour in most areas for a qualified repair professional. Many repairs take an hour or less, with more complicated ones only taking about 2 hours. Expect to pay a $50 to $100 service call fee to have the repair expert come to your home and assess the problem. This fee is usually credited back to the homeowner if they proceed with the repair.

Microwave Maintenance

It is always cheaper to keep your microwave in good working order rather than being forced to pay for costly repairs. Here are some tips for properly maintaining your microwave oven and avoiding future problems:

  • Keep it clean (both inside and out): Failing to clean spills can cause corrosion on the inside and outside of your appliance. Every time you run the microwave, it heats the spills, making it less efficient and forcing it to work harder.
  • Never run it empty: When you run a microwave with nothing in it, the water molecules in the food are absent, redirecting those microwaves back into the magnetron. Over time, this will damage it.
  • Never use metal in your microwave: The microwaves emitted during usage bounce off the metal and burn the interior components of the appliance.
  • Use proper containers: Not all containers, especially plastic, are safe to use in a microwave. Some melt, which can damage the interior of the appliance. Use only microwave-safe containers when heating food, and avoid all metals and plates with gold or silver accents.
  • Cover food when heating: Avoid splashes, which can clog parts and cause corrosion, by covering all foods when heating.
  • Do not over-pack the appliance: Read your instruction manual and follow all weight limitations to ensure the food cooks evenly and you are not overworking the appliance’s motorized parts.
  • Check the door: Be sure the door closes properly every time it is in use. That keeps the microwaves inside and the motor from running too hard.
  • Guard against power surges: Sudden electrical surges can short out many of a microwave oven’s components. Avoid this problem by using a power surge protector. You can usually buy a good-quality one at your local home improvement store for under $40.

Repair vs Replace a Microwave

Microwaves are one of the cheapest kitchen appliances to replace, sometimes making replacement more economical than fixing them. Still, many homeowners prefer to fix what is wrong instead of shopping for a newer model.

Which factors should you consider when deciding to repair or replace your broken model? Most experts agree that age is a major consideration. Microwaves are built to last 8-10 years, so if your model is more than 6 years old, it is probably time for a new one.

The brand and model are also important since higher-end models can cost $1,000 or more to replace versus a few hundred to repair. Lower-end models costing around $300 brand new are likely a better deal than shelling out $150 for the average repair.

No matter how much you love your current model, there are times when replacing it is a must. If your appliance sparks, smokes, or smells like something is burning, it is no longer safe to use and should be replaced. Doors that do not close properly can cost more than $200 to repair, which is usually not cost-effective. Likewise, when your food is not cooking or heating throughout, the fix may cost more than a new appliance.

Consult with a pro who can fix your microwave

Additional Considerations and Costs

  • DIY repair. If you are handy, you may be able to handle something small like replacing the roller guide inside the microwave. But most repairs require specialized knowledge and experience, so it is probably best to call in a qualified professional to handle the job safely and efficiently.
  • Set expectations with your repair professional. It is vital that you talk with your repairman before scheduling an appointment. Make sure the professional knows the brand, make, and model number of the appliance to ensure they have the experience necessary to repair it. Next, ask about fees, including service and travel fees before hiring. It is always best that both parties are clear about expectations before starting a job.
  • Check the warranty before deciding to perform repairs. Not every problem is covered under a manufacturer's warranty, but many are. Check your warranty to see what is covered and what is not.
  • Home warranties. In most cases, your home warranty covers the microwave repair if you have microwave appliance coverage. Also, be aware that many home warranties charge a service fee ranging from $50 to $100 just to send out a repairman. After that fee, however, most repairs are covered, and free replacement is offered with a comparable make and model if your appliance is deemed unfixable.
  • Location. If you live in an area far from town or in a busy metropolitan area with heavy traffic, expect to pay a premium for repair service. Most professionals factor in average travel within their standard fees. But when they must travel more than 10-15 miles or 15-30 minutes, count on them adding an extra travel fee for their service. This can be anywhere from a flat $25 to $50 to an actual mileage fee, with an average of about 58¢ per mile.
  • Accessibility. Another factor that may affect the price of repair is how hard it is for your repair professional to access it. Built-in wall units that must be removed from the wall and reinserted onto brackets, those tucked away under cabinets, or in other hard-to-reach areas may cost more to repair because it takes more time to uninstall and reinstall them.


  • Is it worth fixing a microwave?

A lot depends on the type of microwave oven you have and what is wrong. Fixing a fuse can cost as little as $50, including parts and labor, and is probably worth it. But if the repair cost is a few hundred dollars or your appliance is old, it may be best to buy a new one.

  • How many years does a microwave last?

According to statistics gathered by Consumer Reports, today’s microwave ovens last between 8 and 10 years.

  • What do you do when your microwave stops working?

First, check your power source. Next, call a repair professional and explain the problem. A professional may offer advice over the phone. If not, make an appointment.

  • Can you fix a microwave that does not heat?

Yes, you can fix a microwave that does not heat, but it will be expensive. In most cases, failure to heat is caused by a defective magnetron, which costs an average of $100 to $300 to replace.

  • How much does it cost to repair a microwave?

Statistics show that the average repair bill is around $150. Some problems are inexpensive to repair, but larger problems on higher-end models can cost $200 to $1,000.

  • What would cause a microwave to stop working?

Many things cause a microwave to stop working. It usually has to do with its internal parts like the magnetron, diode, fans, or motors.

  • How do I know if my microwave fuse is blown?

You will see scorch marks or a broken filament inside a glass fuse. For ceramic ones, however, you need to use an ohmmeter or continuity tester to be sure.

  • How much does a magnetron cost?

A microwave magnetron averages $50 to $100.
