One of the main functions of a refrigerator as a home appliance is to keep our foods cold. This is in the backdrop of the fact that keeping food in a cold place will ensure that they remain fresh and may be kept for later use. It therefore, becomes stressful and alarming when a refrigerator cannot carry out its main function of keeping our foods at a cold temperature by being too warm. This alarming problem may be an indication that various parts of the refrigerator are not working properly. Here are some of the fridge service issues to look at when your fridge is experiencing similar problems.
Air Inlet Damper Control Assembly
The air damper is an essential component of the refrigerator as it helps in balancing the air flow in and out of the fridge through the evaporator fan housing. A stuck or broken air damper control may lead to the fridge being alarmingly warm as there will be a lack of a mechanical control of the amount of cold air that enters the fridge. In most cases, the air inlet damper control is an automatic door that operates to let enough and the required air into the refrigerator, especially to the fresh food compartment. In this context, if the damper control does not open automatically as required, then there is the possibility of the fridge receiving less cold air, thereby becoming warm.
In most cases, the air inlet damper control, as well as other components of the assembly such as the baffle is housed in a properly enclosed plastic made from a Styrofoam lining. This is to ensure that there are no possible outlets for any unnecessary air leakage. It then becomes your duty to handle the Styrofoam lining with care when inspecting your fridge’s damper control assembly, as to ensure that there are no damage to both the seal and the Styrofoam lining. In locating the damper control, you should verify that it is intact and can move freely as required. You should thoroughly inspect the damper for any broken parts, and if any problem is noticed, then consider replacing the entire air inlet damper control assembly. If your refrigerator model has a sensor bulb that automatically adjusts its resolution depending on the fridge’s interior temperature, then you should ensure that it is well positioned and working properly in showing you whether your refrigerator is either warm or cold.
A Defective Defrost Thermostat
A warm refrigerator might be an indication of a defective defrost thermostat. When the fridge is working properly, then the defrost thermostat will automatically turn on several times in a day with the main aim of melting away any frost that may have gathered on the evaporator coils. The defrost thermostat works automatically in sensing whether the evaporator coils are cold enough. If this is not the case, then the defrost thermostat may be defective and may not properly sense the temperatures. Under such scenarios, it is always advisable to check the defrost thermostat for continuity and it should be replaced if it reaches the low temperature of its operational range.
