Microwave Repair

Microwave runs but will not heat, sparks inside, or the turntable stopped? I repair over-the-range and countertop microwaves across all major brands in Fort Collins.

Common Problems

  • Runs but food stays cold
  • No power or display dark
  • Turntable not spinning
  • Door will not latch, or microwave runs with the door open
  • Sparking or arcing inside the cavity
  • Loud humming with no heat
  • Control panel unresponsive or random behavior
  • Vent fan will not turn off (OTR), or vent will not exhaust
  • SE or 5E error code on Samsung

My Approach

I repair countertop and over-the-range microwaves across all major brands. Typical work covers magnetrons, high-voltage diodes, door interlock switches, turntable motors, control boards, line fuses, vent motors, and charcoal filters. The three door-interlock switches are the most common repeat item on the Whirlpool, Maytag, and KitchenAid OTR platform. Samsung OTR units have a well-documented SE (stuck button) error and magnetron failure pattern. I work on standard OTR and countertop units; built-in microwave drawers (Sharp, Miele) are limited to replacement work.

Try This First

Before you call, a few things are worth a quick try. If any of these fixes it, you save a service call. If not, give me a ring.

  1. 1

    Check the outlet and GFCI

    Most OTR units sit on a dedicated 20A circuit with nothing else. Confirm the breaker has not tripped.

  2. 2

    Clean the door seal and mating surfaces

    Food residue on the door perimeter can throw the interlock latch alignment over time.

  3. 3

    Clean the grease filter monthly (OTR)

    Soak in hot soapy water or run through the dishwasher top rack per the owner's manual.

  4. 4

    Replace the charcoal filter every 6 to 12 months (non-vented OTR)

    Part number depends on your model; check the manual.

  5. 5

    Reseat the turntable coupler if the plate wobbles

    Do not run the microwave without the plate in place.

  6. 6

    Power-cycle at the breaker for 60 seconds

    NEVER open the microwave cabinet for any reason. The high-voltage capacitor can hold a lethal charge for days after unplugging.

When to Stop and Call Me

A few signals mean stop using the appliance and call a technician. If you see or smell any of these, unplug the unit and reach out.

  • Microwave not heating, for any reason (capacitor hazard; do not open the cabinet)
  • Burning smell, smoke, or visible arcing inside the cavity
  • Door will not latch, or microwave runs with door open (interlock failure; replace immediately)
  • Rust perforating the internal cavity wall (RF leakage risk, replace the unit)
  • Persistent sparking from the waveguide cover
  • Microwave trips a breaker on start (capacitor, diode, or magnetron short)
  • OTR unit hanging crooked or mounting bracket failing (falling-unit hazard)
  • Loud humming with no heat (capacitor or diode failure in progress)

How Long Should This Last

Average Service Life

9 years

Over-the-range units fail earlier than countertops because of heat exposure above the range. For countertop units under roughly the cost of a mid-tier replacement, most component repairs do not pencil out past year 5. Repair-favored items: door switches, diodes, turntable motors, vent motors. Magnetron replacement on a unit past 7 years is usually a replacement decision. Built-in microwave drawers and trim-kit units (Wolf, Thermador) justify repair further because replacement cost is higher.

All Major Brands

I service all major brands. If I can get the parts, I can fix it. Samsung, LG, Whirlpool, GE, KitchenAid, Maytag, Bosch, and more. No brand is too obscure.

I handle every repair personally

We have used Rocky Mountain Appliance several times on a commercial kitchen and I've always been extremely happy with the service. We did have an issue with a stove that he worked on and he immediately rectified the situation at no charge. We will definitely be using him again in the future!

Jake is absolutely amazing! He got my washer fixed in a matter of a couple of days when the original company left us hanging for almost 5 weeks! He is beyond professional, courteous and got my issue taken care of promptly and was more than reasonable in price. I highly recommend using him and will use him for any future appliance issues.

Rocky Mountain Appliance Solutions turned out to be a great choice when our washing machine decided stop working. The repair person was very friendly, knowledgeable, and quick. He diagnosed the problem, explained the solution to me, and provided a very reasonable quote. It's also nice to know that I'm dealing with a local company and not some place pretending to be local.

I called Jake on a Monday, he was able to come Wednesday morning - took a look at my dryer, spent about 20 minutes going to get a couple parts picked up, installed them and voila! We are back in the laundry business! He was very prompt and professional. He goes over your repair costs up front too, and is able to take card payment. Great experience!
