Is It Worth Repairing a Microwave Magnetron?

When it comes to microwave repair, the magnetron is often the make-or-break component. The magnetron is the heart of a microwave, responsible for generating the microwaves that heat your food. If the magnetron is faulty, it can significantly impact the microwave’s performance, and in some cases, even pose a safety risk.

Magnetron Replacement Cost

Replacing a microwave magnetron can be a costly endeavor, often ranging from $100 to $300 for the part alone. When you factor in the labor cost, which can be an additional $50 to $125 per hour, the total repair bill can quickly approach the cost of a new microwave.

When to Repair vs. Replace

As a general rule, it’s recommended to replace the microwave if the cost of repairing the magnetron exceeds half the cost of a new unit. Microwaves can range from $100 to $600 on average, with additional installation costs of $100 to $400 for built-in models.

DIY Magnetron Replacement

For the more technically inclined, DIY magnetron replacement is an option, with costs ranging from $20 to $130 on average. However, it’s important to note that microwaves contain components that can be dangerous, even when unplugged. Attempting DIY repairs without proper knowledge and safety precautions can be risky.

The Bottom Line

In the end, the decision to repair or replace a microwave with a faulty magnetron comes down to a cost-benefit analysis. If the repair cost is reasonable and the microwave is relatively new, it may be worth considering. However, if the magnetron replacement is going to cost as much or more than a new microwave, it’s generally better to invest in a replacement unit.
