It may be worth contacting an appliance repair professional before deciding to replace the fridge, but cracks in the shell usually mean the appliance will need to be replaced.

Look at the rubber gasket all the way around the door to ensure it hasn’t come loose somewhere. If so, you may be able to push it back in. Test the seal in multiple spots by closing the door onto a piece of paper money. Try to pull the bill out of the door slowly. If it easily slides out, you may be able to fix the fridge by replacing the rubber gasket that runs around the edge of the door.

Be sure any kit you purchase is compatible with your fridge. You may have to order a special kit from the refrigerator’s manufacturer. Kits to replace the gasket on most refrigerators cost about $50.

Note that your fridge’s motor will run more often if the door is frequently opened. For instance, if you’re having a party and people are going in and out of the fridge, the motor will run more frequently.

If the fridge is emanating heat, it likely needs new coils. Weigh the cost of repairing your fridge against buying a new one. It is often worth buying a newer, more efficient fridge in these cases.

Whenever you notice a fridge is not working as well as it used to, have it looked at by a professional. For instance, a freezer that’s running too cold is also an issue. Even if it is still working, the fridge may be using more energy than it should, not to mention increasing your energy costs.
