Urgency: High

Important Tips for Ge Models

  • GE microwaves can show smoking or arcing due to door switch, magnetron, diode or waveguide cover issues; specifics depend on model service manual.

Possible Causes

Food residue or spills burning inside cavity

How to Identify: Smoke coincides with visible burnt food residue or smell of burnt food; often during or immediately after heating food.

Part: Microwave cavity interior/waveguide area

Overheated or improper food items

How to Identify: Smoke starts with specific foods overheating (e.g., high fat/oil, or improper containers; the smoke stops once food is removed.

Part: Food contents

Dirty or damaged waveguide cover

How to Identify: Localized smoke near a panel area, possible sparks/arcing before smoke; interior plate near waveguide looks charred.

Part: Waveguide cover

Faulty high-voltage diode or magnetron

How to Identify: Smoke with acrid chemical/electrical burning smell; may pair with failure to heat food and unusual noises.

Part: Magnetron / high-voltage diode

Internal wiring or electrical fault

How to Identify: Smoke accompanied by burning plastic smell, possibly visible damage behind panels, and no direct food cause.

Part: Internal wiring harness
