Is it worth repairing a microwave?

Repairing a microwave is worth it only in a narrow set of cases: a built-in or over-the-range model that is costly to replace and install, a high-end unit, or one still under warranty, where the written estimate is small next to a real price for a comparable new microwave. For a basic countertop microwave, replacement usually makes more sense. No official percentage rule decides it, so compare your actual numbers.

This is a pro-only repair. GE offers no do-it-yourself repair advice for microwave ovens, because of the high voltage, the complexity of the circuitry and the special equipment needed to diagnose a fault.^[1] The decision is about whether to pay a technician, not whether to try it yourself.

Repair it when

• It is built in or over the range. Replacing one of these can mean a new trim kit, a different mounting plate, electrical changes or cabinet work, which adds to the price of the new unit.
• It is under warranty. Check the purchase date and the manufacturer's coverage first, and ask whether a repair business is authorized to do warranty work.
• The part is a simple one and the estimate is clearly small. A worn door latch or a switch is usually a smaller repair than a failed core heating part or control board, so ask what failed.
• It is a premium model you like. A convection or speed-cook oven can cost a good deal more than a plain countertop microwave.

Replace it when

• It is an inexpensive countertop model. A visit fee plus a part can add up to a large share of a new one.
• The repair is a large share of a comparable new microwave. Ask for a firm number for the repair and a real price for the replacement you would buy, and compare the two.
• It has already needed repairs. A second failure usually means other parts are wearing out.
• The cavity, door or controls are damaged. FDA says not to use an oven if the door does not close firmly or is bent, warped or otherwise damaged.^[2] For damage to the door hinges, latches or seals, FDA says to contact the manufacturer for assistance,^[2] and a damaged door is rarely worth chasing on an older unit.
• There is rust, arcing damage or burn marks inside. These suggest the oven has been unsafe for some time.

Comparing estimates fairly

Dollar figures vary by model, brand and which part failed, and we have not found a dated Virginia price source, so use quotes instead of rules of thumb. Ask each business for a written estimate that lists the diagnostic or visit fee, the part, the labor and any tax, and whether the visit fee is credited if you go ahead. Ask what warranty comes with the repair.

DPOR's hiring guide says it is advisable to get at least three written bids or estimates using identical plans and specifications so you can compare prices.^[3] It also says: Do not automatically accept the lowest.^[3] Then price the replacement yourself, including delivery, installation and hauling away the old unit, and compare the totals.

Before you spend anything

Check that the microwave is plugged in and the breaker has not tripped, the door closes firmly, and the timer is not set. If it still will not work, a technician is the next step. See what a technician does to fix a microwave that will not heat for what a visit involves.

When to call a licensed pro

Always, for any internal repair. Choose a business with a written estimate, a clear parts and labor warranty and verifiable references, and compare at least three bids as DPOR advises.^[3] If the replacement is a built-in or over-the-range model, ask whether a new circuit, venting or cabinet changes are needed, because those are electrical and carpentry jobs that call for qualified trades.
