Common Reasons Why Your Whirlpool Refrigerator Is Stuck On Defrost Mode
During the cooling stage of your refrigerator, the appliance will go into self-defrosting mode when the amount of ice being formed within the compartments increases above a certain level.
This is a very important function which prevents the internal components being frozen over.
But if the defrost function continues, it can impact the overall cooling of the appliance as well as stop producing any ice.
Another symptom to look for is the sound of the compressor, if the compressor doesn’t turn itself on, you will not hear the humming sound.
There can either be a problem with the compressor of the refrigerator, or the defrost system and the thermostat is not signaling the compressor to do its job.
Issue With the Defrost Timer
The defrost timer is responsible for regulating the frequency and intervals of the defrost heater being turned on and off.
If there is an issue with the timer, the system will not be informed about when the defrost heater should be turned off or on.
It can cause your refrigerator to both be stuck on defrost mode or not turn on the defrost mode at all.
Depending on the refrigerator model you have, the defrost timer can be either a mechanical dial or electronic.
If you have a mechanical dial, you can test whether turning it is turning on the compressor or not.
You can also check if the dial is stuck or broken. In this case, you will have to replace the dial.
You can locate the timer usually in the fresh food compartment or at the bottom of the refrigerator. Refer to the user manual to get a better idea for your model.
On the other hand, if you have an electrical timer, you won’t be able to manually check it for problems. In this case you should call a professional to look at it.

The defrost heater is the main component involved in the defrosting process. The heater will turn itself on to melt away the frozen condensation from the coils.
A malfunctioning heater can both result in it being turned on all the time and not turning on at all.
If the heater is not turning itself on at all, it could indicate them being burnt out. On the other hand, if the heater is permanently turned on, it could indicate a problem with the wiring or other components.
Call a professional to take a proper look at it.
The thermostat in your fridge is responsible for letting the defrost timer know when the temperature is too low, and the heater should be turned on.
If the thermostat is faulty, it can read the wrong temperature and never turn off the heater or signal it to turn on when it shouldn’t.
