Microwaves have a way of blending into the background. Then one day, your go-to appliance for reheating leftovers, defrosting dinner, or making late-night popcorn starts acting up. Now you’re left wondering: should you repair it or just buy a new one?
The answer isn’t always obvious. Some issues are fixable and cost-effective, while others signal it’s time to move on.
Consider the Age of Your Microwave
Like most appliances, microwaves don’t last forever. On average, they run well for about 7 to 10 years. If yours is nearing the end of that range, repairs may not be the best investment. But if it’s still fairly new, a microwave repair service could be the smarter move. A simple fix can extend its life for years, saving you money in the long run.
The Cost of Repair vs. Replacement
A quick rule of thumb: if the repair costs more than half the price of a new microwave, replacement is probably the better choice. Basic countertop models start around $100, while high-end or built-in units can cost several hundred dollars.
Common microwave repairs, like replacing a faulty door switch or magnetron, often cost between $50 and $200, depending on the issue and the model. If you have a high-end or built-in microwave, repairing it is often the more economical option.
What’s Wrong With It?
Not all microwave problems are created equal. Some are minor and worth fixing, while others indicate deeper issues.
- It’s not heating properly. This could be due to a failed magnetron, diode, or capacitor. These parts can often be replaced, especially in higher-end models.
- The turntable isn’t spinning. A faulty motor or drive coupling is usually to blame—an easy fix.
- The door won’t close or latch. A simple adjustment or replacement of the latch or springs might do the trick.
- Unusual noises or sparks. If the microwave is making odd sounds or sparking, it might just need a new waveguide cover or diode, both inexpensive fixes.
On the other hand, if there’s burnt wiring, a damaged control board, or multiple failing components, replacing it might be the better bet.
Is It a Built-In or Over-the-Range Microwave?
Built-in and over-the-range microwaves aren’t as easy to swap out as a countertop model. They require installation, and replacing them often involves modifications to your cabinetry or venting. That means the cost of a new unit is more than just the price tag—it includes installation, potential cabinet adjustments, and labor.
For these types of microwaves, repairing a microwave is often the better financial decision, especially if the unit is relatively new.
Energy Efficiency and New Features
Older microwaves tend to be less efficient. If yours is using more power than necessary or lacks modern features like sensor cooking, inverter technology, or energy-saving modes, upgrading could be worthwhile. But if your microwave is still performing well, a repair might keep it going for years without the extra expense of a brand-new unit.
