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.

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.
