A sparking microwave can cause a fire inside the cavity if continued in use. The most common causes are a damaged waveguide cover, a metal item accidentally placed inside, or a failing magnetron. Turn off and unplug the microwave and call us for same-day repair in Concord, NH.
Microwaves contain a high-voltage capacitor that can store a lethal electrical charge even when unplugged. Never attempt DIY microwave repair — a trained technician must safely discharge the capacitor before any internal work. All our technicians follow strict microwave safety protocols.
For over-the-range and built-in microwaves ($400–$800+), repair is almost always the right choice. For basic countertop microwaves under $100, replacement may be smarter if the magnetron is dead. Our technician gives you an honest repair vs. replace recommendation every time.
From a completely dead microwave to one that runs but won't heat food, our technicians handle every common microwave failure quickly and safely in Concord, NH.
The most common microwave complaint. The microwave turns on, the light works, and the turntable spins — but food comes out cold. This is almost always a failed magnetron (the component that generates microwave energy). Other causes include a blown high-voltage diode, a failed capacitor, or a defective door switch.
Most Common IssueSparks or arcing inside the microwave cavity are caused by a damaged or burned waveguide cover, food debris on the cavity walls, a faulty stirrer motor, or a deteriorating magnetron. Stop using the microwave immediately — sparking can escalate to a fire. We fix the waveguide cover and inspect the magnetron same-day.
Fire Risk — Stop UsingA microwave turntable that won't rotate is caused by a failed turntable motor, a stripped or broken turntable coupler, or debris blocking the roller guide. The microwave still heats, but food cooks unevenly without rotation. This is typically a quick, affordable repair.
Easy FixA microwave door that won't latch or close properly prevents the unit from starting — this is a safety feature. Common causes are broken door latch hooks, a failed door latch spring, or a misaligned door frame. We replace door latch assemblies for all major microwave brands.
Safety Lock IssueA completely dead microwave has usually blown its internal fuse, has a failed door switch that prevents startup, or has a tripped circuit breaker. For over-the-range microwaves, the issue may be a specific thermal cutoff fuse triggered by overheating from poor ventilation.
Check Breaker FirstA microwave touchpad or control panel that is unresponsive, partially working, or showing a locked symbol has a damaged membrane keypad, a failed control board, or a child lock accidentally enabled. We diagnose and replace control panels and boards for all major microwave brands.
Electronic IssueA microwave making grinding, rattling, or loud humming noises during operation has a failing turntable motor, a worn magnetron cooling fan, or a damaged stirrer blade. Grinding from the fan is a sign that the magnetron may be starting to fail. Address it early before a full magnetron replacement is needed.
Early Warning SignOver-the-range microwaves include a ventilation fan that removes smoke and odors from the cooktop below. A fan that won't run has a failed fan motor, a broken fan switch, or a clogged grease filter. We repair OTR vent systems and replace grease and charcoal filters for all major brands.
OTR SpecificOur technicians carry training and parts for all major microwave manufacturers — countertop, over-the-range, and built-in models.

A microwave that runs but does not heat has almost certainly lost its magnetron — the component that generates microwave radiation.
