Refrigerator Not Cooling? Troubleshooting Guide

When your refrigerator stops cooling, it's a race against time to save your food. Before calling for emergency service, there are several things you can safely check at home.

Immediate Steps

Check the Basics First

Power Supply

- Is the refrigerator plugged in securely? - Check the circuit breaker - Test the outlet with another device

Temperature Settings

- Controls may have been bumped - Digital displays may show error codes - Check both refrigerator and freezer settings

Door Seals

- Close a piece of paper in the door - If it slides out easily, the seal may be compromised - Check for visible damage or debris

Common Causes and What to Check

Dirty Condenser Coils

The #1 cause of cooling problems we see in Greenwich:

Located behind the front grille or at the back

Should be cleaned every 3-6 months

Dust and pet hair reduce efficiency dramatically

Blocked Air Vents

Proper airflow is critical:

Don't overstuff the refrigerator

Keep vents clear of food containers

Ensure air can circulate between compartments

Ice Buildup

Can indicate defrost system problems:

Excessive frost in freezer

Ice blocking air vents

Water pooling under crisper drawers
