Refrigerator not cooling? Check these first.
A refrigerator that stops cooling often has a simple cause: a setting, a blocked vent, a door that doesn’t seal or coils that can’t shed heat. Here is what to check, in order, before you book a repair.

Six checks, in order
Each one comes from the makers’ own help pages. Most take a minute and no tools.
-
Power and controls
Open the door. No light can mean no power, GE says, so check the plug, the breaker and any GFCI outlet it’s on. Then make sure nobody turned the controls off. A demo mode can leave the cooling off, Samsung warns, and KitchenAid says its showroom mode keeps the lights on while nothing cools.
-
The temperature, then a day
GE and Frigidaire suggest 37 °F for the fresh-food side and 0 °F for the freezer; the USDA’s limit is 40 °F or below. After you change a setting, give it about 24 hours before you judge it, GE says.
-
The air vents
Cold air reaches the shelves through vents. Samsung says to keep food 2 inches clear of them, and GE says to move tall containers forward so they don’t block the flow.
-
The door seal
Close the door on a dollar bill and pull it out: Frigidaire says you should feel a little resistance. If it slips out freely, wash the gasket with warm soapy water and try again. A gasket with cuts or tears needs replacing, GE says.
-
Level
The doors should swing shut on their own. If they don’t, GE says to adjust the leveling legs or rollers so the front sits a little higher than the back.
-
Coils and room to breathe
The condenser coils give off the heat taken out of the fridge. Depending on the model they sit behind the base grille, on the back or on top, and GE says most of its models built from 2001 on never need them cleaned, so check your manual. Leave space too: GE asks for at least an inch of air at the sides, top and back, though it says the need varies by style and model.
Unplug it first. Before you touch the coils or take off a grille, unplug the refrigerator or switch off its breaker.
What about the refrigerant?
A refrigerator cools with refrigerant, often called Freon. Three things to know before anyone mentions it.
- Sealed
The refrigerant stays inside a closed loop, what GE calls the sealed system. None of the six checks touches it.
- Checks first
When makers list why a refrigerator won’t cool, they start with settings, vents and seals, then fans, defrost parts and controls.
- A different job
Under section 608 of the Clean Air Act, the EPA sets rules for the technicians who service equipment that could release ozone-depleting refrigerant.
When to call
GE’s rule of thumb: if 24 hours have passed, the controls are set right and the refrigerator is still warm, you may need service. Meanwhile, keep perishables cold somewhere else; our refrigerator repair page shows how long food keeps.
Call or text and we’ll give you the earliest time we have.
Text us the model sticker
It’s usually inside the fresh-food section, on a side wall, the ceiling or under the crisper drawers. Send a photo and tell us which checks you’ve tried.
Text a photo to (754) 285-8880Should I unplug a refrigerator that stopped cooling?
Not once it needs a technician. GE asks owners to keep a refrigerator that needs service plugged in, so the symptoms don’t disappear before the technician sees them. Unplug it only to clean it or to work behind a grille, which GE also advises.
How long does a new refrigerator take to get cold?
About a day. GE says to allow about 24 hours for a new refrigerator to cool down and stabilize, and Samsung allows up to 28 hours with the doors kept shut.
