Introduction
Microwaves are one of the most convenient kitchen appliances found in nearly every home. From reheating leftovers to making popcorn or even cooking meals, microwaves make life easier. But like all appliances, they can break down. When they do, repairs can be tricky—and expensive. Ever wondered what makes microwave repairs costly? The answer lies in one critical part.
In this article, we’ll explore which component is the most expensive part of a microwave, why it costs so much, and how to keep your appliance working longer without spending a fortune.
Microwaves have become a kitchen essential in nearly every home. They’re fast, convenient, and make reheating or cooking meals easy. But like any appliance, microwaves can break down over time. When they do, repair costs can vary depending on which part is damaged. So, what exactly is the most expensive part of a microwave? In this article, we’ll break down the key components of a microwave and highlight which one hits your wallet the hardest when it fails.
Understanding Microwave Components
A typical microwave is made up of several working parts that each serve a specific function. The door, keypad, and turntable are visible from the outside, while the important heating elements sit hidden behind the scenes. Some of these internal parts are relatively affordable, while others come with a high price tag if they need replacing.
Here are the main parts found in most microwaves:
- Magnetron
- High-voltage capacitor
- Control board
- Diode
- Door switch
- Turntable motor
Each of these plays a vital role in how your microwave operates. However, not all of them are expensive to replace.
The Magnetron: The Heart of the Microwave
The magnetron is the most essential—and most expensive—part of a microwave. This component is responsible for generating the microwave radiation that heats your food. Without it, your microwave simply won’t function.
Replacing a faulty magnetron can cost anywhere from $100 to $250, depending on your model and the labor involved. In some cases, this cost may be close to the price of a new microwave, especially if your unit is older or out of warranty.
Most service calls involving no heat in the microwave usually trace back to this part. Because it requires careful handling and specific knowledge to replace, the repair must be done by a trained technician.

Other Costly Parts to Watch
While the magnetron tops the list, some other parts can also drive up your repair bill:
- Control Board: Acts as the brain of the microwave. A new board can cost $80–$150.
- High-Voltage Capacitor: Stores electrical energy needed to run the magnetron. Replacing this part may cost around $50–$100.
- Touchpad or Keypad: When these fail, the cost to replace them varies widely depending on the model—typically $50–$120.
On the other hand, simpler components like door switches or turntable motors are cheaper to replace and can often be repaired for under $50.
Repair or Replace?
If your microwave is more than 7–8 years old and the magnetron fails, it may not be worth repairing. Instead, replacing the appliance might be the better option. However, if your microwave is newer and still in good condition, investing in a magnetron replacement can extend its life.
It’s always a good idea to get a professional diagnosis first to weigh your options correctly.

How to Avoid Expensive Repairs
Preventative care is key to avoiding costly microwave problems. Here are some helpful tips:
- Don’t run the microwave empty—this can damage the magnetron.
- Clean the interior regularly to avoid buildup that can block vents.
- Don’t slam the microwave door—this can wear out door switches and cause alignment problems.
- Avoid using metal objects inside, which can damage internal parts.
With proper care, your microwave can last for many years without major issues.
