An installed microwave is built into the kitchen, with its own trim, mounting and ventilation. Fix Cheetah repairs over-the-range, built-in, drawer and combination speed ovens across Vancouver, Metro Vancouver, the Fraser Valley and Sea-to-Sky corridor.
We service microwave drawers from brands such as Sharp, Wolf, Thermador, Bosch, GE and KitchenAid, along with over-the-range and built-in models from major manufacturers. A countertop microwave may be cheaper to replace, but an installed unit can be worth repairing because its trim, cabinetry and ventilation are already matched to the kitchen.
Microwave repair requires particular safety discipline. The high-voltage capacitor can retain a dangerous charge even after the appliance is unplugged. Internal high-voltage diagnosis and component replacement should therefore be left to trained technicians.
When to stop using your microwave
Unplug the appliance if there is sparking, a burning smell or a damaged door. Other symptoms may not be immediately dangerous but still deserve attention.
- Food remains cold while the microwave appears to run
- Sparking or arcing inside the cavity
- Loud humming, buzzing or grinding
- Door does not close squarely or latch correctly
- Display or keypad becomes unresponsive
- Drawer mechanism struggles to open or close
How we diagnose microwave faults safely
Diagnosis involves controlled testing of the high-voltage system, including the magnetron, diode, capacitor, transformer or inverter board depending on the design. We also check thermal protection and door interlock switches.
For installed models, we inspect the trim, ventilation and mounting. Over-the-range units also have fan motors, grease filters and lighting circuits. After work involving the door or microwave system, appropriate safety checks are performed before the unit returns to service.
Over-the-range, built-in and drawer microwave repair
Over-the-range units combine microwave cooking with ventilation over the cooktop. Built-in units sit inside trim kits, while drawer microwaves use motorized mechanisms, position sensors and gear assemblies. Speed ovens add convection or grill heating, creating two separate heating systems to diagnose.
Microwave care tips
Food splatter and grease are common contributors to cavity arcing and ventilation problems.
- Cover food when practical to limit splatter
- Keep the cavity and waveguide cover clean
- Never operate the microwave empty
- Do not use metal or unsuitable foil inside the cavity
- Clean over-the-range grease filters regularly
- Close microwave drawers gently to protect their mechanisms
Repair or replace your microwave?
For a basic countertop unit, replacement is often more economical. For built-in, drawer, over-the-range and speed oven models, repair can preserve the existing trim and cabinet fit. Magnetrons, switches, motors, keypads and control components may be serviceable.
We consider the appliance's age, condition, part availability and replacement complexity before recommending repair or replacement.
5 Most Common Microwave Issues and How to Fix Them
Microwave not heating
A failed magnetron, diode, capacitor or inverter system can stop microwave production while the fan, light and turntable continue operating. A door interlock or thermal protection fault can also prevent heating. Do not open the cabinet to test these components.
Microwave sparking inside
Arcing can come from metal, damaged cavity coating or a contaminated waveguide cover. Stop using the appliance and unplug it. If the waveguide cover is scorched or sparking continues after removing unsuitable objects and cleaning the cavity, professional inspection is required.
Microwave turntable not turning
Check that the glass tray is seated correctly on the roller ring and centre coupler. Food debris or a damaged coupler can stop rotation. If the motor still does not move the tray, it needs testing and replacement.
Microwave not turning on
A dead display can result from loss of power, a main fuse, door interlock, thermal cut-out or control fault. Check the breaker and, for countertop models, the outlet. Internal fuse and switch work should be left to a technician.
Over-the-range microwave fan not working
The vent fan may have a motor, control relay or sensor fault. Some models also start automatically when the cooktop below becomes hot, which can be normal. Clean the grease filters and allow the appliance to cool before arranging service for persistent problems.
Microwave repairs involve high voltage, so leave the testing to us. We diagnose the circuit safely, replace magnetrons, switches, fans and boards, and service installed microwaves across Metro Vancouver, the Fraser Valley and the Sea-to-Sky corridor.

Microwave FAQ
Why is my microwave running but not heating?
The high-voltage heating system may have a failed magnetron, diode, capacitor or inverter board. Door interlock and thermal protection faults can also stop heating.
Is it worth repairing a microwave?
For a small countertop model, replacement is often more practical. Built-in, drawer, over-the-range and speed oven units can be worth repairing because replacement may require trim or cabinet changes.
Can I repair a microwave myself?
We do not recommend opening the cabinet. The high-voltage capacitor can retain a dangerous charge after unplugging.
Why does my over-the-range microwave fan turn on by itself?
Many models use a heat sensor to start the fan when the cooktop becomes hot. If it continues with a cold cooktop, the sensor or control system may need testing.
Why is my microwave sparking?
Metal, unsuitable cookware and a damaged or grease-contaminated waveguide cover are common causes. Stop using the unit until the cause is identified.
Do you repair microwave drawers?
Yes. Drawer mechanisms, motors, sensors, controls and heating components can be diagnosed on supported models.
Do you service speed ovens?
Yes. Speed ovens require diagnosis of both the microwave and convection or grill systems.
