Why is the microwave running but not heating food?

When the display and turntable operate normally but food remains cold, the high-voltage section has failed—most commonly a burned-out magnetron, a shorted high-voltage diode, or an open thermal cut-off protector.

Why is there sparking inside my LG microwave?

Sparking (arcing) typically happens when the mica waveguide cover plate becomes saturated with grease or food splatter, or when the enamel paint inside the cavity has chipped, exposing bare metal to high-frequency microwaves.

Can unresponsive touch panel buttons be repaired?

Yes. Unresponsive touch keypads occur when conductive ribbon traces degrade due to kitchen humidity and heat. We either repair the conductive traces or replace the touch membrane overlay with an original LG replacement.

Specialized LG Microwave Oven Repair Services

Microwaves operate with high-voltage transformers converting 230V mains into over 2,000 volts to energize the magnetron. Untrained tampering poses severe electrical shock hazards. Our certified appliance specialists possess the necessary high-voltage discharge probes and safety gear to safely diagnose your LG microwave at home.

Operating directly out of Ground Floor, Poonam Sagar Complex, Mira Road East, we stock original LG magnetron tubes, high-voltage diodes, 0.8A to 1.2A high-voltage fuses, and replacement mica waveguide covers.

Common LG Microwave Problems We Fix

Food Not Heating Up

The magnetron filament is open or high-voltage diode has shorted out. Tested with high-voltage meters and replaced with genuine OEM magnetron.

Internal Sparking (Arcing)

Burned mica waveguide sheet or scorched cavity paint causing high-energy plasma arcs. We replace the waveguide cover and apply microwave-safe dielectric barrier.

Touch Panel Not Responding

Start button or number keys unresponsive due to ribbon cable corrosion or microswitch failure. We restore track continuity or replace the membrane keypad.

Glass Turntable Not Rotating

Stripped nylon drive coupler or burnt 21V/230V synchronous roller motor. Repaired on-site so food cooks evenly again.

Frequently Asked Questions

Can an LG microwave be repaired at home safely?

Yes. Our technician carries specialized capacitor discharge tools and microwave radiation leak detectors to service your oven safely right on your kitchen counter.

What causes the turntable plate to stop turning?

The synchronous motor under the floor of the oven cavity can burn out, or the plastic drive coupler linking the motor spindle to the glass tray has cracked. Both are easily replaced in under 20 minutes.
