My Hotpoint microwave runs but does not heat. Can I fix it myself?

Please do not open it. A microwave that runs without heating usually has a failed magnetron, diode or capacitor, and the high-voltage circuit can hold a lethal charge even when unplugged. Our technicians discharge the circuit safely before testing.

The microwave in my University City apartment sparked. Can I keep using it?

No. Stop using it and unplug it or switch off its breaker. Sparking can come from metal left inside, a burned waveguide cover or damage to the cavity paint. Report it to your landlord, and a technician can find the cause and say whether it is safe to repair.

Why does our apartment microwave only start if we push the door hard?

That usually means a worn door switch or a broken latch hook, which keeps the microwave from detecting that the door is closed. It is a common repair on heavily used units. Do not tape or force the door, since those switches are safety devices.

Hotpoint Microwaves: What We Check First

Hotpoint microwaves are mostly over-the-range models that double as a vent hood above the cooktop, with some countertop models in the lineup as well. The over-the-range versions combine a magnetron and high-voltage circuit for cooking, a turntable motor, a cooktop light and a vent fan that exhausts or recirculates steam and grease. That combination means a single unit can have several unrelated failures, and the cooking side involves stored voltage that is dangerous to anyone who opens the case.

Failed door switch blowing the internal line fuse
Magnetron or high-voltage diode failure leaving food unheated
Vent fan motor grinding or failing to shut off
Control panel unresponsive after a thunderstorm power surge

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

Microwaves Used Hard in Apartments Near Campus

In apartments near UNC Charlotte and the light rail stations, the over-the-range microwave may be the most-used appliance in the kitchen. Doors get yanked open mid-cycle and slammed shut, which wears the door switches and latch hooks. Metal containers or foil cause arcing that pits the interior and can burn through the waveguide cover.

Failures to watch for include sparking inside, a burning smell, a unit that runs with no heat, and a dead keypad. Stop using a microwave that sparks. In family homes farther out, over-the-range units more often lose a fan motor or lights after years of steam rising off the cooktop below.

Report the problem to your landlord, and do not try to open the case, since internal parts can hold a dangerous charge. The technician tests the switches, magnetron and controls, replaces a damaged waveguide cover where needed, and explains whether the repair is worth it.
