How it works
The coil location varies by model, and some modern refrigerators have designs that require little or no consumer cleaning. Always unplug the appliance and follow its manual before removing a panel or using a coil brush.
What people often miss
Cleaning cannot fix a failed compressor, fan, seal, or refrigerant problem. Persistent warming or unusual cycling needs proper service.
