Are Microwaves Repairable Or Do I Need to Replace?

Microwaves are great inventions that simplify cooking certain foods. But like all appliances, they can have problems and need repair. Whether you need to replace your microwave depends on several factors. These include the cost of repairs and the appliance’s age.

Should You Repair?

Microwave repair is often possible. However, repairing the microwave requires expertise. It also poses safety risks due to the high voltage capacitors that can retain a charge even after unplugging. Whether you can repair your microwave depends on how easy it is to access the broken part. If it’s inaccessible, a professional repair can cost more than if you could just replace the part. Another factor that can impact your decision to repair or replace is the age of your appliance. If your unit is more than a decade old, it’s likely time to get a new one.


Microwaves can be repaired, but there are certain times when they are not cost-effective to repair. For instance, if the microwave sparks or smokes or does not heat food properly, it may be time to replace it. Similarly, if the magnetron is broken, it should be replaced. This is one of the most important components in a microwave, and it transforms the electrical current into microwave energy. The cost of repairing this part averages $75 to $300. This includes a replacement motor and roller guide, which sits under the plate and rotates it smoothly. Some repairs can be done by yourself, but most require specialized knowledge and experience. This is why it is best to hire a professional to do the job. It is important to set expectations and discuss fees before hiring a repairman.

Repairable Or Not?

A microwave oven’s lifespan is typically five years, and if yours has exceeded that mark, it might be time to consider buying a new one. As technologies continue to improve and appliances become more energy efficient, it’s often easier and less expensive to just buy a new model than repair an old one. If your microwave doesn’t heat food properly, it may have a fault with its high voltage diode or magnetron, both of which are essential for generating the power necessary to turn on the microwave and cook your meals. Faults in these parts can prevent your microwave from producing the heat it needs, so be sure to get them repaired as soon as possible. When a microwave tray won’t rotate, it usually means that the drive motor or coupler that powers the motor have stopped working. If this is the case, you’ll need to replace the motor and coupler. It’s also a good idea to replace the roller guide that sits on top of the glass tray, which can also stop rotating.
