My Whirlpool microwave went completely dead. Is it worth fixing?

Often yes. A totally dead microwave frequently has a blown main fuse caused by a failed door switch, which is an inexpensive repair. We test the switches and fuse safely and tell you the cost before doing the work.

My over-the-range microwave in East Charlotte runs but doesn't heat. Is it fixable?

Often, yes. A failed door switch, high-voltage diode or magnetron can cause it, and the switch is the least expensive of those. We test each part and compare the repair cost with replacing an over-the-range unit, which involves removing and remounting it.

Why does the microwave in our apartment keep blowing a fuse?

Frequent use wears the door switches, and a failing switch often blows the main fuse. Replacing just the fuse usually does not last. If you rent, let your landlord know, since the owner typically books and approves the repair.

Whirlpool Microwaves: What We Check First

Whirlpool's microwaves are mostly over-the-range units that serve as a vent hood, plus a smaller number of countertop and built-in models. The over-the-range design includes a vent fan, a cooktop light, grease filters and a charcoal filter for recirculating installs. Inside, a magnetron, high-voltage transformer, capacitor and diode generate the microwaves, and a set of door switches makes sure power is cut whenever the door opens.

Door switch failure blowing the main fuse, unit totally dead
Diode, capacitor or magnetron failure, running but not heating
Thermal cut-off tripped by blocked vents or cooktop heat
Turntable motor or vent fan worn out from years of use

The full explanation, including what you can safely check yourself and when repair beats replacement, is in our Whirlpool microwave repair guide.

Daily Use and Over-the-Range Wear

In a household where several people reheat meals every day, the microwave door is opened constantly, so door latches and the switches behind them fail more often than anything else. Updated ranch kitchens and townhomes in 28212 and 28215 often have an over-the-range model that also vents the stove, and grease and steam from heavy cooking clog its filters and wear the fan motor. A microwave that sparks usually has a damaged waveguide cover or food buildup inside, and it should not be used until it is cleaned or checked.

What Is Safe to Check and When to Call

Never open the outer case, because the capacitor inside can hold a dangerous charge long after the unit is unplugged. You can reset the breaker, clean the interior and the grease filters and confirm the door shuts firmly. If it still will not heat, we test the switches, fuse, diode and magnetron. We tell you plainly when a countertop unit is cheaper to replace than repair.
