The freezer is another space in your kitchen refrigerator to store other food items that require to be frozen to ensure that their quality is kept for a long time. There are some instances in which homeowners may not be able to appreciate what the freezer can provide.

Temperature is an important factor for the freezer to work, and it must maintain a specific level to ensure that it won’t compromise the quality of the food stored. But, there are some instances that the freezer may have some temperature problems, which can cause it not to defrost properly. Different factors cause the issue, and it is important to determine this as soon as possible 

Freezer Is Not Freezing? Here’s 5 Reasons Why

An issue with theDefrost Control Board

This electronic board in the refrigerator directs how often to run the automatic defrost cycle. When this board has some issues, the fridge will not go into defrost cycle.

An issue with the Defrost Sensor and Fuse

The defrost sensor system helps to monitor the temperature of the evaporator. This part has a fuse that will act as a backup if the sensor fails. If the defrost sensor fails to shut off the defrost heater, the fuse will blow, and the heater will be forced to shut off. In this case, the defrost heater will no longer be operating and would cause the fridge not to defrost.

Issue Defrost Timer

The defrost timer turns on several times each day to help remove any frosts that may have accumulated on the evaporator. If the timer has an issue, it may not be able to move into the defrost cycle or be able to send power to the defrost heater during the cycle. 

An issue with the Defrost Heater Assembly

This is a part of the freezer that turns on several times throughout the day to melt away any of the first accumulated on the evaporator coils. If the defrost assembly is defective, this will cause the defrost system not to work, and frost will continue to build upon the evaporator coils.

An issue with Defrost Thermostat

If the defrost thermostat is defective, the thermostat contacts will not close, and this will cause the thermostat not to be able to provide the power to the defrost heater. If the defrost thermostat doesn’t have a continuity result when it reaches the low temperature of its operating range, it needs to be replaced.
