Most fridges stop cooling because of dirty condenser coils, a blocked air vent, a failed evaporator or condenser fan, a frosted-over evaporator coil, or a bad start relay. Check the temperature setting, clear the vents and clean the coils first. If it's still warm after 24 hours, call a technician.
First, Keep Your Food Safe
Keep both doors closed as much as you can. A closed fridge stays cold for about 4 hours. A full freezer stays frozen for about 48 hours, and a half-full one for about 24.
If the fridge has been warm for more than 4 hours, move milk, meat, leftovers and medicine into a cooler with ice. Use a thermometer if you have one. The fridge should be at or below 40°F to keep food safe.
Common Reasons a Fridge Stops Cooling
1. The temperature was changed
Kids, cleaning or bumping a dial can change the setting. The fridge should be about 37°F and the freezer about 0°F.
2. Air vents are blocked
Cold air flows from the freezer into the fridge through small vents. A milk jug or pile of food in front of a vent can block it.
3. Dirty condenser coils
Coils under or behind the fridge release heat. Dust and pet hair make the fridge work harder and cool less, especially in hot North Carolina summers.
4. Condenser fan has stopped
This fan cools the coils and compressor. If it's not spinning, the fridge overheats and stops cooling well.
5. Evaporator fan has failed
This fan pushes cold air from the freezer into the fridge. If the freezer is cold but the fridge is warm, this fan is a top suspect.
6. The evaporator coil is frozen over
If the defrost heater, sensor or timer fails, frost builds up behind the freezer panel and blocks airflow.
7. Bad start relay
The relay helps the compressor start. A clicking sound every few minutes, with no cooling, often points here.
8. Worn door seals
Torn or loose gaskets let warm air in. You may see sweat or frost near the door.
9. Compressor or sealed system problem
This is the least common cause, but the most costly. It needs a trained technician to diagnose.
Safe Checks You Can Do at Home
- Check the dial or display and reset it to 37°F for the fridge and 0°F for the freezer.
- Move food away from the vents inside the fridge and freezer.
- Unplug the fridge, remove the bottom grille, and vacuum the coils. Plug it back in.
- Listen near the bottom back of the fridge. You should hear the condenser fan running when the fridge runs.
- Open the freezer, press the door switch, and listen for the evaporator fan.
- Close a dollar bill in the door. If it slides out easily, the seal may need work.
Give the fridge up to 24 hours after cleaning coils or changing settings. If it's still warm, a part has likely failed.
Fridge Warm but Freezer Cold: What It Means
This is one of the most common calls we get. In most cases, the freezer is working but cold air isn't reaching the fridge section. The usual causes are a failed evaporator fan, a frosted coil from a defrost problem, or a stuck air damper.
These are all repairable, usually in one visit. Learn more on our refrigerator repair page.
When to Call a Refrigerator Technician
- The fridge is still warm 24 hours after basic checks.
- You hear clicking, buzzing or grinding that's new.
- Frost is building up on the back wall of the freezer.
- Water is leaking inside or under the fridge.
- The fridge runs nonstop and still won't get cold.
