Quick reference
What to Do When Your Microwave Stops Working
Sparks, smoke or burning smells
Unplug the microwave when it is safe to do so. Do not continue using a unit with a damaged door or one that repeatedly trips the breaker.
No heat, no start or failed controls
Note whether the light, fan, display and turntable work. These details help describe the symptoms before the diagnostic visit.
Send the model and installation type
Photograph the model label and tell us whether the unit is countertop, built into cabinetry or mounted over the range.
Common symptoms
Microwave Problems We Diagnose and Repair
Similar symptoms can have different causes, so the failed component should be confirmed before parts are replaced.
Microwave Not Heating
The appliance runs, but food remains cold or heats unevenly. Possible causes include the magnetron, high-voltage diode, capacitor, door switch or control circuit.
Sparking or Arcing Inside
A damaged waveguide cover, burned interior surface, metal contact or internal fault may cause visible sparks. Stop using the appliance until it is inspected.
Microwave Will Not Start
Door switches, fuses, power connections, touch controls and control boards can prevent the microwave from operating.
Door Will Not Close or Latch
A damaged latch, hook, spring or interlock switch may keep the door from closing securely or prevent the unit from starting.
Turntable Not Rotating
The turntable motor, drive coupler, roller guide or control circuit may be responsible when the tray stops moving.
Display or Controls Not Working
A fuse, touchpad, control board or incoming power problem may leave the display dark or make the controls unresponsive.
Loud Humming or Grinding
Unusual sounds may come from the cooling fan, turntable motor, magnetron or another internal component.
Vent Fan or Light Failure
Over-the-range units may develop separate problems with the exhaust fan, cooktop light, switches or electronic controls.
Do not remove the microwave cover yourself. High-voltage components can retain a dangerous electrical charge even after the appliance has been unplugged.
Equipment type
Countertop, Built-In and Over-the-Range Microwave Repair
Portable Countertop Microwaves
Countertop units can usually be moved without changing cabinetry. The decision to repair depends on the model, age, condition, parts availability and replacement cost.
- Door-switch and latch problems
- Fuse and power failures
- Turntable and control issues
- No-heat complaints
Installed Microwave Systems
Built-in and over-the-range models require careful access. OTR units may also provide ventilation and cooktop lighting. Many issues can be diagnosed in place, while some repairs require removal from the mounting system.
- Heating and control problems
- Door and interlock faults
- Vent-fan and light failures
- Installation-specific access
Repair decision
Should You Repair or Replace the Microwave?
The $89 diagnostic visit identifies the fault and provides the information needed to compare repair with replacement. The diagnostic charge is not a flat price for every completed repair.
Repair May Make Sense When
- The microwave is built into cabinetry or mounted over the range
- The appliance is otherwise in good condition
- Replacement would require installation, trim or ventilation work
- The required part is available at a reasonable cost
Replacement May Be More Practical When
- A basic countertop model is older or heavily worn
- The cabinet, door or interior has significant physical damage
- Several major components have failed
- The repair approaches the installed cost of a suitable replacement

Frequently asked questions
Microwave Repair FAQ
Why is my microwave running but not heating?
Possible causes include the magnetron, high-voltage diode, capacitor, door switch or control component. These parts operate at dangerous voltage, so internal diagnosis should be handled by a qualified technician.
Is it worth repairing a microwave?
Repair often makes sense for built-in and over-the-range units because replacement can involve mounting, cabinetry, ventilation and installation. For countertop models, the decision depends on age, condition, repair cost and replacement price.
Is it dangerous if the microwave is sparking?
Stop using it if sparking continues after all metal objects and foil have been removed. A damaged waveguide cover, burned interior surface, door issue or failing component may require inspection.
Can an over-the-range microwave be repaired in place?
Many problems can be diagnosed in place. Some repairs require the appliance to be removed from its mounting bracket so internal components can be accessed safely.
Do you offer same-day microwave repair?
Same-day and next-day appointments may be available depending on technician schedules, location, equipment and parts availability. Contact us to check the earliest opening.
What information should I send when booking?
Send the service address, brand, model number, installation type, error code and a short description of the problem. A photo of the model label is helpful.
