Repair vs. Replace a Microwave

The cost to install a microwave ranges from $110 to $190, plus $100 to $700 for the appliance. This may be higher or lower than the $50 to $400 you’ll need to repair the existing one. As a general rule, you should consider replacement if:

  • The microwave is almost 10 years old.

  • You’ll pay at least half the cost of replacement.

  • You can’t find replacement parts that fit the brand and model.

Built-in appliances or those with special features like convection tend to run the highest to replace. Repair may be a better choice for these units.

DIY vs. Hire a Professional

At a rate of $50 to $100 per hour plus parts, hiring a professional to repair your microwave may or may not be necessary. You might feel comfortable replacing a glass tray or light bulb on your own. By comparison, you’ll want to find microwave repair companies near you for services such as:

  • Replacing a magnetron.

  • Putting in a new turntable motor.

  • Wiring a power cord.

When you’re ready to contact at least three pros for an estimate, be sure to ask if mileage and parts are included in the total.
