Microwave repair prices by type of repair

Cost to replace a magnetron

The cost to replace a magnetron is $100 to $300 on average, depending on the microwave brand and model. Microwave magnetron prices are $50 to $200 for the part alone. A failed magnetron often means other parts like the diode also need replacing.

  • The cost to replace a magnetron in a GE microwave is $120 to $380.

  • Samsung microwave magnetron replacement costs $130 to $300.

Microwave diode replacement cost

A microwave diode replacement costs $80 to $170 on average. When a diode burns out, the microwave stops heating. The diode is an electrical part that powers the magnetron. Technicians often replace the magnetron and diode at the same time.

Microwave repair FAQs

Can microwaves be repaired?

Microwaves can be repaired if the compatible replacement parts are available. However, the manufacturer may stop producing replacement parts for units more than 4 to 7 years old.

Is it worth repairing a microwave?

Premium built-in microwaves less than 5 years old are worth repairing due to the expensive replacement cost. Cheap or countertop microwaves are typically cheaper to replace than repair.

Is it worth replacing a magnetron in a microwave?

Replacing a magnetron in a microwave is typically not worth it for countertop models because the cost is often more than buying a new microwave. Replacing a magnetron in expensive built-in microwaves is typically worth it if multiple parts aren’t also failing.

How long do microwaves last?

Microwaves last 7 to 10 years before they need replacing. To make a microwave last longer, clean it often, don’t run it while empty, and keep all the unit’s connections dry.

Who fixes microwaves?

Professionals who fix microwaves include:

  • Factory-trained technicians from appliance-repair centers

  • Official brand service centers

  • Contractors from home-improvement stores

  • Home warranty service contractors

  • Electricians near you
