Loud humming, buzzing or grinding
A loud hum, especially with no heat, often points to a failing magnetron or a shorted diode. Grinding usually comes from the turntable or fan.

Microwave problems we fix in Crystal Lake
A microwave that hums but leaves the food cold usually has a failed diode, magnetron or door switch. Our technicians diagnose over-the-range and built-in microwaves in Crystal Lake, and we tell you honestly whether a repair beats a replacement. Please don't open the case yourself: the high-voltage capacitor inside can hold a dangerous charge even when unplugged.
Countertop microwave that stopped working
Countertop models are often not worth a service visit. Unless it's a higher-end unit, we'll recommend replacement.
Heating weaker than it used to
Slow, uneven heating often means the magnetron is near the end of its life. We test it and tell you if replacing it is worth it.
Sparking inside the microwave
A small panel on the inside wall, the waveguide cover, can burn through from food splatter and start arcing. Replacing it is often a simple fix if caught early.
Fan runs by itself
If the fan won't shut off, we test the thermal sensor and the control before replacing parts.
Turntable not turning
A turntable that stops is usually a worn motor, a cracked coupler or the glass tray sitting off its track. Motor replacement is a modest repair.
Built-in or drawer microwave failure
Built-in units cost more and are harder to swap, so repair is usually worth a look. We check parts availability before quoting.
Display dead or keypad not responding
Dead keypads and blank displays are common on older units. Whether it's worth fixing depends on parts availability, and we check that first.

Microwave Repair questions from Crystal Lake homeowners
Why is my microwave running but not heating?
The magnetron, diode and capacitor are the usual suspects. We test them safely and quote the repair.
Is it worth repairing a microwave?
We give you an honest answer by type and age. A rule of thumb many use: if the repair costs more than half of a new unit, replace it.
How much does microwave repair cost?
A door switch and a magnetron are priced very differently. You get the number in writing, along with our repair-or-replace view.
What usually breaks in a microwave?
The high-voltage parts and the door switches fail most often, followed by keypads and turntable motors.
Do you repair over-the-range microwaves?
We do, including the vent fan and cooktop light. They're the most common microwaves we repair.
Do I need a permit for microwave repair in Crystal Lake?
It depends on the scope. Crystal Lake's rule in short: Kitchen alteration handout (Nov 2019) requires a contractor list and two sets of plans showing floor plans, electrical layout, structure and plumbing changes; inspections for rough electrical, plumbing, framing, insulation and final. We handle the permit when one is needed with City of Crystal Lake Community Development - Building Division.
