Commercial Sharp Microwave Microwave Not Heating — Boonton ZIP 07005, NJ

A dryer that blows cold air is almost always caused by a blown thermal fuse. This is a safety device that burns out when the dryer overheats — usually due to a clogged exhaust vent. We replace the fuse AND clean the vent to prevent it from blowing again.

Yes — a restricted exhaust vent is the leading cause of thermal fuse failure in dryers. When the vent is blocked, heat builds up, the safety thermal fuse cuts power to the heating element, and your dryer stops heating. We clear the vent as part of every dryer heating repair.

A thermal fuse replacement costs $100–$180. Heating element replacement (electric) costs $150–$280. Gas valve coil replacement costs $130–$250. We always diagnose first to identify the exact failing component.

The heating element is a coiled resistance wire inside an electric dryer that generates heat when electricity passes through it. Signs of failure include no heat at all, heat that shuts off mid-cycle, or clothes that take 2+ cycles to dry. A multimeter test confirms whether it has continuity.

Gas dryer heating failures are usually caused by failed igniter, faulty gas valve coils that control gas flow to the burner, a tripped thermal fuse, or a defective radiant flame sensor. Gas dryers require a qualified technician for safe diagnosis and repair.

Yes — a blocked vent causes heat buildup that is a leading cause of home fires. According to FEMA, dryer fires cause approximately 2,900 home fires per year. After any dryer heating repair, we inspect and clear the full exhaust path as a safety measure.

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.

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.
