Your refrigerator stopped cooling and you need to know: is this a $150 fix or a $1,500 replacement? Here are the seven most common causes, ranked from cheapest to most expensive, so you know what you’re dealing with before anyone touches anything.
The condenser coils release heat from the refrigerant. When they’re coated in dust and pet hair — which happens over 1-3 years of normal use — the fridge can’t release heat efficiently and the interior temperature climbs. This is the most common cause of gradual cooling loss.
Fix it yourself: Unplug the fridge. Find the coils (usually on the bottom behind the kick plate, or on the back). Vacuum them with a brush attachment. Takes 15 minutes. Cost: $0.
How to tell if this is your problem: The fridge is cooling, but not as well as it used to. It’s been getting worse gradually. You can’t remember ever cleaning the coils.
The evaporator fan circulates cold air from the freezer compartment into the refrigerator section. If it stops working, the freezer may still be cold but the fridge section warms up. This is one of the most common calls we get in Tampa Bay.
How to tell: Open the fridge. Listen. You should hear the fan running. No sound = likely the fan motor. Also: freezer is fine but fridge is warm.
Repair cost: $80-150 for the part, 1-2 hours labor. Total: $150-250 in most cases.
The start relay gives the compressor the jolt of electricity it needs to start. When it fails, you’ll hear a click every few minutes as the compressor tries to start and fails. The fridge gets warm.
How to tell: Remove the start relay from the compressor (it’s a small component on the side of the compressor). Shake it. If it rattles, it’s dead. Replace it.
Cost: $10-40 for the part online. This is one of the few refrigerator repairs a handy homeowner can do themselves.
Modern frost-free refrigerators have a defrost heater, defrost thermostat, and defrost timer that work together to melt frost off the evaporator coils every 6-12 hours. When any of these fail, frost builds up on the coils until airflow is completely blocked — and the fridge stops cooling even though the compressor is running fine.
How to tell: Remove the back panel inside the freezer compartment. If the coils are completely coated in a thick layer of ice, the defrost system failed.
Repair cost: $100-200 depending on which component failed. All are repairable.
The rubber seal around the refrigerator door keeps warm air out. Over time it cracks, hardens, or gets food debris stuck in it. Warm air infiltrates constantly, making the compressor run continuously to compensate — and eventually the fridge can’t keep up.
How to tell: Close a dollar bill in the door. If you can pull it out easily with no resistance, the seal isn’t sealing. Also: if the compressor seems to run all the time, this is a likely cause.
Repair cost: $50-100 for the gasket, 30-60 minutes labor.
On most modern side-by-side and French door refrigerators, a fan draws air over the condenser coils. If this fan fails, the refrigerant can’t cool down properly and the whole cooling cycle breaks down. Often confused with the evaporator fan, but it’s located near the compressor (usually at the bottom rear).
How to tell: Listen near the bottom rear of the fridge. If there’s no fan noise while the compressor is running, this fan may have failed.
Repair cost: $80-180 for the motor, 1-2 hours labor.
The compressor is the heart of the refrigerator — it compresses the refrigerant and keeps the cooling cycle going. When it fails, nothing works. This is the most expensive repair, and on older or budget refrigerators, it’s often the point where replacement makes more financial sense than repair.
How to tell: The compressor is hot to the touch but not running (or trying to run and clicking off). No cooling at all.
Repair cost: $300-600 for compressor replacement. On a refrigerator over 10 years old, replacement is often the better call — we’ll tell you honestly which way it goes.
Note: LG refrigerators from certain production years had a compressor defect that resulted in a class action settlement. If you have an LG, check whether yours qualifies before paying for a repair.
If the repair is under 50% of what a comparable new refrigerator costs, repair. If it’s over 50% and the unit is over 8 years old, replacement is usually the better financial decision. We tell every customer this up front — and we won’t push you toward a repair that doesn’t make sense.
