Troubleshooting frost, ice buildup, and air circulation problems
These are often caused by failed defrost components or broken fan motors. Left unchecked, they can lead to warm spots or overworked compressors.
This is often caused by a failed defrost heater or sensor. Learn how to replace a defrost heater or how to replace a defrost sensor to restore normal operation.
Freezer is fine, but fridge is warm
Air may not be circulating properly due to a failed fan motor. Depending on your model, follow these steps to replace an evaporator fan motor in a top freezer or side-by-side refrigerator.

RCA refrigerator FAQs
Why is my refrigerator not cooling?
A common cause is dirty condenser coils or a faulty thermostat. Check airflow, inspect the evaporator fan, and clean the coils to improve performance.
Why is there water under my refrigerator crisper drawers?
This could indicate a clogged defrost drain. When the defrost cycle runs, melted ice has nowhere to go and collects inside the compartment.
Why does my refrigerator make a loud buzzing or clicking sound?
Buzzing can mean the ice maker is trying to fill without water, while clicking often signals compressor relay issues. Check the water supply and inspect the start relay.
How often should I replace my refrigerator water filter?
Every 6 months, or sooner if your water tastes off or the flow slows. Old filters can let contaminants through or clog the system.
Why does my fridge smell even after cleaning it?
Hidden food spills, clogged drains or mold in the drip pan can trap odors. Use baking soda or charcoal filters to absorb lingering smells.
