If by "choke refrigerator refrigeration" you are referring to a situation where the refrigerator's refrigeration system is not working correctly or is "choked," this can happen due to various reasons. Here are some common causes of refrigeration issues in a refrigerator:
Refrigerant Leak: The refrigerant is the substance responsible for absorbing and releasing heat in the refrigeration cycle. If there is a leak in the refrigerant system, it can lead to a loss of cooling capacity and result in poor performance or complete failure of the refrigerator to cool properly.
Compressor Issues: The compressor is the heart of the refrigeration system, as it compresses the refrigerant gas, raising its temperature and pressure. If the compressor is faulty or fails, it can disrupt the entire cooling process, leading to a choke in the refrigeration system.
Clogged Condenser Coils: The condenser coils are responsible for releasing heat from the refrigerant to the surroundings. If these coils get clogged with dust, dirt, or debris, they won't be able to efficiently dissipate heat, causing the refrigeration system to choke and lose cooling capacity.
Faulty Evaporator Fan: The evaporator fan circulates cool air throughout the refrigerator. If the fan malfunctions, the cold air won't be distributed evenly, leading to temperature imbalances and potential choking of the refrigeration system.
Thermostat Issues: The thermostat controls the temperature inside the refrigerator. If it is not functioning correctly, it might not signal the refrigeration system to start or stop, causing irregular cooling and potential choking.
Defrosting Problems: If the automatic defrosting system is not working as it should, ice can build up on the evaporator coils, obstructing the airflow and causing the refrigeration system to choke.
Electrical Problems: Any electrical issues with the refrigerator's components, such as wiring problems or faulty switches, can disrupt the refrigeration process and lead to a choke.
In the event of a choke or refrigeration issue with your refrigerator, it's best to contact a qualified appliance repair technician to diagnose and fix the problem. Attempting to repair refrigeration systems without proper knowledge and tools can be dangerous and may cause further damage to the appliance.
