Why Use Oregon Appliance Repair for Your Microwave
— Certified Technicians, 90-Day Warranty
Microwave not heating? Sparking inside? Turntable stopped turning? We fix it right, and back every microwave repair with a 90-day warranty.
A microwave looks simple from the outside, but inside it runs on a high-voltage system. A magnetron produces the cooking energy, a transformer and capacitor power it, door switches keep it safe, and a control board runs the whole thing. When one part fails, the microwave stops heating, starts arcing, or won’t start at all. Our factory-trained and certified technicians know these systems well, so we diagnose accurately, explain what we found, and get the job done right. Most microwave repair appointments are scheduled within 1 to 3 days of your call.
What We Repair
Our certified technicians work on countertop, over-the-range, built-in, and drawer microwaves, plus microwave and wall oven combination units, convection microwaves, and speed ovens. We also provide commercial microwave repair for restaurants, cafés, and break rooms. Whatever the brand or configuration, we’ve seen it and fixed it.

Microwave Brands We Service
We handle microwave repair for every major brand, from everyday countertop models to high-end built-ins: Bosch, KitchenAid, LG, Samsung, Whirlpool, GE, Frigidaire, Electrolux, Thermador, Wolf, Miele, Viking, Dacor, Jenn-Air, Siemens, and many more.
Built-in microwave repair, along with drawer and speed oven work, is a different job from swapping out a countertop unit. These units are wired into your cabinetry, often paired with a wall oven, and many local shops won’t work on them. We repair them regularly, and if your microwave is part of a combination unit, our oven repair team can service the whole stack in one visit.

Microwave Maintenance: What to Look For
A few simple habits prevent most of the microwave repair calls we see. Here’s what our technicians recommend.
Wipe up spills right away. Food splatter that sits inside the cavity hardens with every use. Over time it can scorch the interior paint and soak into the waveguide cover, which is one of the most common causes of sparking. A damp cloth and mild detergent after a messy cook is all it takes.
Check the waveguide cover. This is the small panel, usually on the right side wall of the cavity, that covers the opening where energy enters the oven. If it looks greasy, burned, or cracked, have it replaced. It’s an inexpensive part, and a damaged one can lead to arcing that harms the magnetron.
Use the right containers. Metal, foil, and twist ties cause arcing, and some plastics warp or melt. The FDA’s microwave oven guidance covers safe cookware and everyday use if you’re ever unsure.
Never run it empty. With nothing inside to absorb the energy, it reflects back toward the magnetron and can shorten its life. Keep a cup of water inside if kids or guests tend to hit “Start” by accident.
Clean or replace filters on over-the-range models. Grease filters should be cleaned about once a month. If your microwave recirculates air instead of venting outside, the charcoal filter typically needs replacing every six months.
Close the door gently and watch for changes. The door switches are what allow your microwave to run. Slamming the door wears them out, and a door that no longer closes firmly is a reason to stop using the unit and call for service. The EPA’s overview of microwave oven radiation explains why a damaged door or seal matters.
Leave internal repairs to a technician. A microwave’s high-voltage capacitor can hold a charge even after the unit is unplugged. Cleaning, filter changes, and turntable swaps are fine to do yourself. Anything behind the outer cabinet calls for professional microwave repair.
Repair or Replace? Here’s How to Think About It
Most microwaves last about 7 to 10 years. Built-in and over-the-range models often run longer, and they cost more to replace once you add installation and the challenge of matching an existing cutout.
If you have a built-in, drawer, over-the-range, or combination unit that is under 7 years old, repair is almost always the smarter move. Common failures like a door switch, turntable motor, diode, or control board are straightforward fixes, and replacement often means new trim kits, rewiring, or cabinet work.
If you have a basic countertop model, or any unit over 9 years old facing a major failure like the magnetron or control board, replacement may make more sense than a microwave repair. It’s also worth checking the CPSC recall database before paying for any repair, since a recalled model may qualify for a free fix or refund from the manufacturer. We’ll tell you honestly which way it goes. We’re not here to sell you a repair that isn’t worth doing.
