How do freezers work?
Freezers work the same way, whether you have a fancy smart fridge or a standard one. They use:
- A refrigerant to help absorb heat from inside the unit.
- A compressor to increase the refrigerant's temperature and pressure.
- Condenser coils to dissipate the heat outside the freezer.
5 common reasons your freezer may not be cooling properly
Freezers can be finicky, and several usual suspects could be causing your freezer to lose its cool. When your freezer isn’t working as it should, start your search with these easy-to-find culprits.
1. Air is escaping
A good seal on your freezer door is critical. If the seal is damaged or the door doesn't close properly, cold air can escape, and warm air can enter, lessening the freezer's ability to stay cool.
2. Dirty condenser coils
Dusty condenser coils can't release heat efficiently. Cleaning them can improve your freezer's ability to cool. First, unplug your freezer. Move the unit away from the wall, then use a vacuum or brush to clean the coils, which are usually on the back of your unit or its side panels.
3. A blocked evaporator fan
When your freezer is cold but not freezing, the problem could be the fan. The evaporator fan moves cold air throughout the freezer. If ice buildup or other obstructions block the fan, it can't circulate air effectively, leading to cooling issues.
4. A faulty evaporator fan
If the evaporator fan is struggling or broken, it won't circulate cold air within the freezer. The fan may need to be repaired or replaced to keep your freezer working at its best.
5. A broken start relay
This part helps power the compressor. If it breaks, the compressor might not work correctly, preventing the freezer from cooling.
