You open the fridge and it feels barely cool, the milk is warm, and you are worried about the food inside. A refrigerator that is not cooling is one repair you cannot put off, but the causes are a short, predictable list, and a couple of them you can check in five minutes. Here is what is going on, what to do right now to protect your food, what it costs, and when to call a technician.
Quick answer: A refrigerator usually stops cooling because of dirty condenser coils, a failed condenser or evaporator fan, a bad start relay or compressor, or a faulty thermostat or control board. Start by cleaning the coils underneath or behind the fridge, checking that the door seals shut, and making sure the vents inside are not blocked. If the whole unit is warm and the compressor is silent, that points to the start relay or compressor and needs a technician. Food stays safe about four hours, so act quickly. In Michigan you can reach a same-day technician at (586) 837-0811.

Do this first to protect your food
A closed refrigerator keeps food safe for about four hours, and a full freezer for about 48 hours. Keep both doors shut as much as possible, move anything perishable into a cooler with ice, and get the repair booked. The faster it is fixed, the less you lose.
Why your refrigerator is not cooling
- Dirty condenser coils. The coils shed heat, and when they are coated in dust and pet hair they cannot, so the fridge runs warm. This is the single most common cause and the easiest to fix.
- A failed condenser or evaporator fan. Fans move cold air through the fridge. When one quits, the compressor may run but the cold air never circulates.
- A bad start relay or compressor. The compressor is the pump at the heart of cooling. If the start relay fails, the compressor will not run, and the whole fridge goes warm and silent.
- A faulty thermostat or control board. These tell the fridge when to cool. When one fails, the fridge may never call for cooling at all.
- A worn door seal. A seal that no longer grips lets warm air leak in, so the fridge runs constantly and still cannot keep up.
First checks before you call
- Clean the condenser coils underneath or behind the fridge with a brush and vacuum. If they were caked, this alone can fix it.
- Confirm the temperature setting was not bumped, and set the fridge to about 37°F.
- Check the door seal closes tight. A dollar bill shut in the door should tug slightly when you pull it.
- Make sure the inside vents are not blocked by food, which stops cold air from spreading.
- Listen for the compressor. A faint hum means it is running. Total silence with a warm fridge points to the relay or compressor.
If the coils are clean, the seal is good, and it still will not cool, the fan, relay, compressor, or control needs testing, and that is a technician’s job.
Is the whole fridge warm, or just the fridge section?
This tells you a lot. If the whole unit is warm, including the freezer, the problem is central: the compressor, start relay, or condenser fan. If the fridge is warm but the freezer is still cold, that is a different fault, usually blocked airflow or a defrost problem, and we cover it in detail in why a fridge is warm but the freezer is cold. If the fridge cools but you have no ice, see ice maker not working. If a standalone freezer is the problem, see freezer repair.
Refrigerator not cooling, by brand
Samsung refrigerator not cooling
Samsung fridges often stop cooling from a frost buildup on the evaporator coil behind the back panel, caused by a defrost fault. Many models show an error code that points to it.
Whirlpool refrigerator not cooling
Whirlpool units (and Maytag and KitchenAid on the same design) most often lose cooling at the evaporator fan, the start relay, or the thermostat. Cleaning the coils rules out the easy cause first.
LG refrigerator not cooling
LG fridges with a linear compressor can lose cooling if the compressor or its control fails, which is often covered by an extended sealed-system warranty. The evaporator fan is another common cause.
Frigidaire and GE refrigerator not cooling
Frigidaire and GE fridges commonly stop cooling from dirty condenser coils, a failed condenser fan, or a bad start relay. Coils first, then the fan.
How much does it cost to fix a refrigerator that is not cooling?
| Repair | Typical cost |
|---|---|
| Condenser coil cleaning | Often a service call only |
| Start relay | $120 to $250 |
| Condenser or evaporator fan | $150 to $350 |
| Thermostat or control board | $150 to $400 |
| Compressor | $300 to $600 |
Most no-cooling repairs land between $150 and $500. A repair is usually worth it on a fridge under about 10 years old. See our refrigerator repair cost guide and the Michigan appliance repair cost guide.

Frequently asked questions
Why is my refrigerator not cooling?
Most often dirty condenser coils, a failed condenser or evaporator fan, a bad start relay or compressor, or a faulty thermostat. Start by cleaning the coils and checking the door seal.
What is the most common reason a fridge stops cooling?
Dirty condenser coils and a failed evaporator fan are the two most common causes. Both stop the cold air the fridge needs from being made or moved.
Is my food safe if the fridge is not cooling?
Food stays safe about four hours in a closed refrigerator and about 48 hours in a full freezer. Keep the doors shut, move perishables to a cooler, and book same-day service.
How much does it cost to fix a refrigerator that is not cooling?
Most repairs run $150 to $500 in Michigan. A start relay or fan is $150 to $350, and a compressor is the priciest at $300 to $600.
Is it worth repairing a fridge that is not cooling?
Usually yes if it is under about 10 years old and the fault is a fan, relay, or thermostat. A failed compressor in an old fridge may be worth replacing instead.
Why is my fridge not cooling but the freezer is still cold?
That is a separate fault, usually blocked airflow between the compartments or a defrost problem, rather than a dead compressor. It has its own common fixes.
