Why Is My Freezer Not Freezing?

Why Is My Freezer Not Freezing?

A freezer not freezing can make even the most relaxed person feel hot under the collar. A freezer that’s stopped working doesn’t have to mean hundreds of dollars down the drain. Figuring out what causes a freezer to stop freezing is the first step to fixing it—saving your freezer and your budget.

1.Freezer Air is Escaping

If you find your freezer cold but not freezing, the first thing you should do is test your freezer door. You may have failed to notice that an item is sticking out enough to keep the door ajar, meaning that precious cold air is escaping your freezer.

Similarly, older or poorly installed freezer door seals might cause your freezer temperature to drop. You can test your freezer door seals by placing a piece of paper or dollar bill between the freezer and door. Then, close the freezer door. If you can pull out the dollar bill, your freezer door sealer needs to be repaired or replaced.

2.Freezer Contents are Blocking the Evaporator Fan.

Another reason your freezer is not working could be poor packing of its contents. Make sure that there is enough space under the evaporator fan, usually in the rear of the freezer, so that the cold air emerging from the fan can reach everywhere in your freezer.

3.Condenser Coils are Dirty.

Dirty condenser coils can reduce your freezer’s overall cooling capacity since dirty coils make the condenser retain heat rather than release it. This causes the compressor to overcompensate. To prevent this from happening, make sure to clean your condenser coils regularly.

4.Evaporator Fan is Malfunctioning.

More serious reasons that your freezer is not freezing involve malfunctioning internal components. If your evaporator fan is not working correctly, first unplug your refrigerator and remove and clean the evaporator fan blades. Ice buildup on evaporator fan blades often prevents your freezer from properly circulating air. If you notice a bent fan blade, you will need to replace it.

If the evaporator fan blades are spinning freely, but the fan won’t run, you may need to replace a defective motor or repair broken wires between the fan motor and thermostat control.

5. There is a Bad Start Relay.

Finally, a freezer that isn’t freezing might mean that your start relay is not working as it should, meaning that it isn’t giving power to your compressor. You can conduct a physical test on your start relay by unplugging your refrigerator, opening up the compartment at the back of your freezer, unplugging the start relay from the compressor, and then shaking the start relay. If you hear a rattling noise that sounds like dice in a can, your start relay will have to be replaced. If it does not rattle, that might mean that you have a compressor issue, which will require professional repair assistance.
