Testing and Replacing a Whirlpool Refrigerator Thermostat

If you want to know how test and replace Whirlpool Refrigerator Thermostat, follow this article and get more information ...!!!

A Whirlpool Refrigerator Thermostat can be fail in two ways:

1. Open Position

2. Closed Position

If the Whirlpool Refrigerator Thermostat fails in the open position, then unit will not run all time. Remove the screws from the evaporator housing and pull the housing down(make sure that unit is unplugged). Locate all the wires attached to the thermostat and remove them. You can connect the two wires together and tape with electrical tape. Plug the unit back in or turn on the breaker. When unit runs then replace the thermostat.

If the Whirlpool Refrigerator Thermostat fails in the closed position, the unit will run all the time. Running Refrigerator Thermostat constantly will cause the evaporator to freeze up and it will restrict the airflow and causing the temperature to rise. Follow the same instructions which described above to test the unit and replace the refrigerator thermostat if necessary. Also be sure to deliquesce the evaporator before turn the unit back on.

Suppose, if the evaporator continues to freeze up after replacing thermostat, call to the service company or else you can contact us to know other problems and get a immediate solutions. 

Low Pressure Control: This is also a type of control. Low Pressure Control is located in the compressor compartment. This connected into the refrigeration lines, controls the temperature by using pressure of refrigerant flowing through the line. To replace Low Pressure Control we need a service technician to fix the problems.

1. Thermostatic (Evaporator Coil Sensing Type or Air Sensing Type)

2. Low Pressure Control (Air Sensing Refrigeration Thermostat)

Let's start with Temperature Thermostatic Type Controls. An air-sensing thermostat type, senses the air temperature. The control sensor tube is mounted in evaporator housing. The evaporator coil sensing type is located inside the unit, usually at the top where the refrigerator fan motor is secured. The thermostatic has a straight capillary or sensor inside the refrigerator. The capillary tube is mounted on the outside of the evaporator coil and pushed into the tube, that is mounted front of the evaporator.

An Evaporator Coil Sensing Thermostat: Coil capillary tube attached to the evaporator sensing thermostat. The coiled tube end and evaporate sensing capillary push into a hole that is in the evaporator. It senses the temperature of the evaporator coil rather than air temperature.

These to temperature controls are not interchange. Suppose you put an air-sensing thermostat control in place of evaporation sensing control, then the evaporator unit will shut down permanently, this causing the temperature to rise. Suppose, instead of air-sensing control if you put an evaporation sensing control, then unit will continue to run, this causing the evaporator to freeze up. When this happen there will be little airflow that causes temperature to rise.
