Fridge Not Cooling? Check This Before Calling It Dead

"My fridge isn't cooling" is one of the broadest calls we get, because it can mean anything from a completely warm refrigerator to one that's just running a few degrees warmer than it should. The good news is that a lot of the common causes are on the simpler end of the scale, not a dead compressor.

The one almost everyone skips

Condenser coils, usually underneath or behind the fridge, pull heat out of the unit as part of the cooling cycle. When those coils get packed with dust and pet hair, the fridge has to work harder and often can't keep up, especially in the hotter months. This is sometimes purely a cleaning job: clear the coils, and the fridge cools normally again. It's also the single easiest thing to rule out before assuming something's actually broken.

When it's frost, not dust

If the coils are clean and it's still not cooling right, the next common cause is a frosted-over evaporator or a failed defrost component. The evaporator is supposed to cycle through a defrost period automatically; when that stops happening correctly, ice builds up on the coil until it can't do its job of pulling heat out of the fridge compartment anymore.

Other things worth checking

Water pooling inside the fridge is frequently a clogged defrost drain, one of the more common and less expensive things to put right. And if the ice maker has stopped working while everything else seems fine, that's usually the water inlet valve, the fill line, or the ice maker module itself, again standard parts rather than a sign the whole unit is failing.

Is it worth fixing?

Often, yes. A lot of what shows up as "not cooling" traces back to dust, frost, or a single part, none of which say much about the overall health of the refrigerator. Where it gets to be a real replacement conversation is a compressor that's actually failed, since that's a bigger job on an already-older unit, and worth weighing against the age of the machine and what a new one would cost.
