GE Microwave: burnt smell
What is this symptom?
If your GE microwave emits a persistent burnt smell during or after use, it may indicate food residue burning, overheating components, or potential electrical issues. This distinct odor, different from normal food smells, can be alarming and requires your attention. Addressing the source promptly is essential to maintain your microwave's performance and safety.
Important Tips for GE Models
- GE microwaves often list waveguide cover damage and high-voltage component overheating as specific causes of burning smell.
Possible Causes
Food residue or burnt food inside cavity
How to Identify: Burnt or charred food particles visible on walls, ceiling, floor, or turntable; smell only during cooking of foods prone to splatter
Part: Interior cavity surfaces, turntable
Damaged or dirty waveguide cover (mica)
How to Identify: Visible charring, warping, arcing, or damage on the waveguide cover, often near the microwave’s upper interior side
Part: Waveguide cover
Overheating or failure of high-voltage components (capacitor, power supply board, magnetron)
How to Identify: Burnt smell persists after cleaning; possible reduced heating performance; visible scorch marks on components if accessed
Part: High-voltage capacitor, power supply board, magnetron
Thermostat or control board malfunction
How to Identify: Persistent burning smell without food inside; electrical smells not tied to food residue; possible intermittent operation
Part: Thermostat, control/relay board
DIY Solutions
Clean interior and remove burnt residue
- Unplug and cool microwave.
- Mix equal parts water and vinegar in a microwave-safe bowl and heat for ~3–5 minutes to create steam.
- Allow to sit 15 minutes, then open and wipe all interior surfaces.
- Remove and wash turntable and support ring; check for remaining residue.
Inspect waveguide cover for damage
- Unplug microwave.
- Remove interior cover to access waveguide panel.
- Inspect for damage, burns, or warping.
- If damaged, order correct replacement part and install per manual.
- Reassemble and test microwave.

Where can I find the model number?
Check the rating label around the door, lid, frame, rear panel, or inside the appliance cabinet. Use the complete model number, including suffixes.
Verify the complete model and part number on the retailer's compatibility page before ordering.
Other parts options
Check related components first; use model search as a fallback.
Power Control Board
Distributes and switches electrical power for the appliance's major loads.
Microwave Magnetron
Generates microwave energy for heating food and requires high-voltage service procedures.
Capacitor
Stores electrical energy to assist in starting or running the motor efficiently.
