Possible Causes

Compressor or condenser fan overheating/intermittent operation

How to Identify: Burning smell coming from exterior back of fridge, visible overheating or scorch marks near motor wiring; temperatures fluctuate as compressor cycles irregularly. External cabinet may feel unusually hot.

Part: Compressor / condenser fan motor

Failing compressor start relay or overload kit

How to Identify: Fridge struggles to start cooling, compressor cycles irregularly, internal temperatures fluctuate widely, potential smell as electrical components struggle. Professional inspection often recommended.

Part: Compressor start relay/overload

Interior light bulb staying on

How to Identify: Warm/hot bulb inside fridge, localized smell near bulb; typically not related to major temperature fluctuations.

Part: Interior light / door switch

Thermostat / temperature sensor malfunction

How to Identify: Refrigerator cycles incorrectly, failing to maintain set temperatures; fridge may overcool sometimes and undercool at other times.

Part: Thermostat / thermistor

Food spoilage or other non-mechanical odor source

How to Identify: Smell mostly inside fridge unrelated to electrical components; odor persists when fridge is off; cleaning and discarding old food reduces smell.
