A refrigerator that isn't cooling is one of the most stressful appliance problems you can have — especially in the middle of an Upstate summer, when temperatures in Greenville push into the 90s and your fridge is working overtime to keep food safe. Before you call a technician, there are a handful of quick checks you can do yourself. About half the "not cooling" calls we get turn out to be one of the issues below.
1. Check the Temperature Settings
It sounds obvious, but it happens all the time: someone bumps the temperature dial while reaching for a jar, or a child plays with the digital controls. The fridge compartment should be set between 35°F and 38°F, and the freezer at 0°F. If the settings look right but nothing is cooling, try turning both dials all the way down for an hour and see if you hear the compressor kick on. No response usually means a deeper electrical issue.
2. Clean the Condenser Coils
This is the #1 cause of cooling problems we see in Greenville homes — especially homes with pets. The condenser coils (usually on the back or underneath the fridge) release heat as the refrigerant cycles. When they get caked with dust, pet hair, and lint, the fridge can't shed heat efficiently and the compartment temperature creeps up. Unplug the fridge, pull it away from the wall, and vacuum the coils with a brush attachment. If you've never done it, you'll be amazed what comes out — and you should plan to do it every 6–12 months going forward. We have a full walkthrough in our 5 easy steps to clean refrigerator coils guide.
3. Inspect the Door Seal (Gasket)
The rubber gasket around the door is what keeps cold air in and warm air out. If it's cracked, torn, or covered in sticky residue, your fridge is constantly losing cold air and the compressor never gets a break. Test it with a dollar bill — close the door on it, then try to pull it out. If it slides out with no resistance, your seal isn't sealing. Clean the gasket with warm soapy water first; if that doesn't help, the gasket needs to be replaced. This is also the most common cause of condensation on the outside of the fridge or frost building up unevenly in the freezer.
4. Check Airflow and Don't Overpack
Cold air needs to circulate. If the fridge or freezer is packed wall-to-wall, the vents that move cold air between compartments get blocked — and you'll often see the freezer stay cold while the fridge section gets warm. Look for the air vents (usually on the back wall) and make sure nothing is pressed against them. Also leave a few inches of clearance behind and above the fridge so the heat being released by the coils has somewhere to go. A fridge crammed into a tight cabinet with no ventilation will struggle no matter what.
5. Listen for the Fans
Open the freezer and listen carefully — you should hear a quiet fan running. That's the evaporator fan, and it's what blows cold air from the freezer into the fridge compartment. If you don't hear it, the fan motor may have failed or be jammed with ice. The condenser fan (near the compressor at the back) should also be running whenever the compressor is. A failed fan is a common, fixable problem, but it does usually require a technician to access and replace.
6. Test the Compressor — and Know When to Call a Pro
The compressor is the heart of your fridge. Put your hand on it (the black, football-shaped part at the back) — it should feel warm and you should hear a low hum when it's running. If it's silent and cold, or if it's clicking on and off rapidly, you likely have a failed compressor, a bad start relay, or a refrigerant leak. These are not DIY repairs — refrigerant work in particular requires EPA-certified handling. At this point, it's time to call a professional refrigerator repair technician. Don't keep the fridge running with a struggling compressor; it can damage the sealed system and turn a $200 repair into a $800 one.
