Is it safe to repair a microwave myself?

No. Microwave capacitors can hold a lethal charge of up to 2,000 volts even when unplugged. Always call a certified professional for microwave repair. Our NJ technicians are trained in high-voltage appliance safety.

My microwave is sparking inside — what should I do?

Stop using the microwave immediately. Sparking is usually caused by a damaged waveguide cover, a burnt-out stirrer motor, or metal accidentally left inside. Call ProFix at (973) 718-9373 — we can diagnose whether the unit is economically repairable or should be replaced.

My over-the-range microwave fan won't stop running — why?

An over-the-range microwave that won't stop running the fan has a failed thermal switch or control board. A stuck relay keeps the fan running after the auto-cool cycle should end. We can diagnose and fix same-day.

Are you certified to repair Kenmore appliances?

Yes. Our technicians are factory-trained and certified for Kenmore appliances. We use genuine OEM Kenmore parts for all repairs, which is required to maintain your warranty and ensure the highest quality repair.

How much does it cost to repair a Kenmore appliance?

Repair costs vary by appliance type and issue. Typical Kenmore appliance repairs in New Jersey range from $120 for simple fixes to $450+ for compressor or control board replacements. We provide an exact upfront quote before starting any work.
