Professional Microwave
Repair Service
Fast, safe, and certified domestic microwave repairs across Illawarra, South West Sydney, and South Sydney. We repair built-in microwaves, convection combination ovens, and smart inverter units—fixing no-heat magnetron faults, internal sparking, turntable motor failure, unresponsive touchpads, and door latch microswitches.
Common Microwave Problems We Fix
Microwaves contain high-voltage capacitors storing lethal electrical charges even when unplugged. Our licensed technicians safely diagnose and repair all faults.
Runs Normally But Doesn't Heat
When the turntable spins and the countdown timer works but food remains cold, the high-voltage magnetron, high-voltage diode, or transformer has failed.
Magnetron ReplacementSparking / Arcing Inside Cavity
Loud crackling and bright flashes usually stem from a carbonized waveguide mica cover, grease buildup on the antenna, or chipped internal cavity paint.
Waveguide CoverGlass Turntable Not Turning
Uneven cooking results from a seized synchronous turntable motor underneath the base, a cracked roller drive coupler, or broken guide ring wheels.
Drive Motor & CouplerTouchpad Buttons Not Responding
Unable to set cook time or press start? A worn keypad membrane switch, oxidized ribbon cable connector, or main control board failure needs servicing.
Membrane & PCBDoor Latch & Microswitch Glitches
Microwaves have three safety interlock microswitches. If the door hook breaks or a switch fails out of sequence, the unit refuses to start or trips fuses.
Door InterlockTripping House Fuse or RCD
The moment start is pressed, the household safety switch trips. This points to a shorted high-voltage capacitor, shorted magnetron, or blown thermal line fuse.

Microwave Repair Questions
Helpful answers on built-in units, capacitor safety, and repair viability.
Is it worth repairing a built-in microwave oven?
Yes, almost always! Built-in microwaves and combination convection ovens are custom-fitted to cabinetry cutouts with specialized trim kits. Replacing an integrated unit often costs between $800 and $2,500+ and frequently requires expensive carpentry modifications. Professional repairs typically resolve the issue at a fraction of the replacement cost.
Why is my microwave running normally but not heating food?
When the lights turn on, the fan blows, and the plate turns, the control electronics are working. The no-heat symptom indicates a fault in the high-voltage generation circuit—most commonly a worn-out magnetron vacuum tube, a shorted high-voltage diode, or an open-circuit high-voltage capacitor. Our technicians carry these standard parts for prompt replacement.
Is it safe for a homeowner to open and repair a microwave?
No. Microwaves are among the most hazardous household appliances to open. They contain large internal capacitors that store between 2,000 and 5,000 volts of electricity—capable of delivering a fatal electric shock even days after the appliance has been unplugged from the wall. Repairs must only be conducted by a certified appliance technician with high-voltage discharge equipment.
What causes sparks inside the microwave cavity?
Internal arcing (sparks) is usually caused by a burnt or carbon-soaked waveguide mica cover plate on the side of the cavity. When food splatters burn onto the cover, they become conductive and catch fire/spark. Replacing the mica cover plate and sanitizing the antenna channel quickly and safely resolves the issue.
