Whirlpool microwave repair

• Runs but food stays cold

  Magnetron, high-voltage diode or capacitor. All three sit in the high-voltage circuit.

• Nothing happens when the door closes

  A door interlock switch, the most common microwave fault by a wide margin.

• Loud buzzing while running

  A failing high-voltage transformer or a diode on its way out.

• Turntable will not turn

  The turntable motor or its coupler. Simple and inexpensive.

• Sparking inside the cavity

  Stop using it. A damaged waveguide cover or burnt cavity paint arcs and gets worse quickly.

• Over-the-range fan or light dead

  The vent fan motor or the lamp assembly, separate from the microwave circuit itself.

• Ramen came out the same day, diagnosed the problem and brought it back to life. He has all the right tools and knows how to use them. The problem was hard to diagnose after the initial repair but he nailed it. He's friendly and professional. He is definitely worth hiring. He will be my first call from now on when I need an appliance repaired.

• Thank you so much! Great customer service. Came and fixed our washer, looks good as new! Hire him

• Tim was very professional and did his job correctly but was sent a defective part. Ramin came and replaced the defective part and my stove works again. After an initial problem that wasn't their fault, masterfix did an excellent job. I would not hesitate to use them again. Thanks Tim and Ramin!

What goes wrong with Whirlpool microwaves?

Dryer thermal fuses tripping from restricted vents is the fault we attend most on this combination. Whirlpool builds the most repairable appliances we see. Parts are widely stocked, diagrams are honest, and a fifteen-year-old Whirlpool is usually worth fixing.

Is it worth repairing a microwave?

For built-in, drawer and over-the-range units, usually yes. For a countertop model, the repair often costs more than a replacement and we will say so before you book.

Can I replace a door switch myself?

Please do not. The high-voltage capacitor holds a dangerous charge even with the appliance unplugged, and it sits right beside the switches.

Do you repair microwave drawer units?

Yes, including Sharp and Bosch drawer models. They need pulling from the cabinet, which adds time.

Do you carry Whirlpool parts for this?

We stock the common failures listed on this page. Anything model specific is ordered after the diagnosis, and we tell you the wait before you commit. Every part carries 90 days of warranty.
