Understanding Common Refrigerator Compressor Problems
When a compressor is not working correctly, a variety of issues may arise.
Refrigerators are essential home appliances for most homeowners. Like all appliances, they can experience issues from time to time. This article will detail some common issues with the compressor component, and offer insights on how they can be repaired.
The compressor is integral to refrigeration; it utilizes coolant to maintain temperature, keeping food and drinks cold. The coolant goes through a cycle that includes compressing of the coolant and pushing it through coils that ultimately keep food cold.
Recognizing compressor issues
When a compressor is not working correctly, a variety of issues may arise. Most commonly, food and drink are not kept at a consistent cold temperature. In some cases, the fridge may stop working entirely, resulting in spoiled food and damage to the fridge itself.
Compressor relay
In addition to understanding compressor function, it is beneficial for homeowners to know how power is supplied. Many refrigerators simply connect to a wall outlet and continuously use power to run. However, some newer models incorporate compressor relay systems; these can prevent a fridge from running at full power all the time, increasing lifespan. Fridges without compressor relays are more vulnerable to overheating and damage that can follow.
Symptoms of a faulty compressor
Identifying a compressor failure can be crucial. Common indicators include:
Unusual noises: a loud buzzing or clicking sound from a fridge may indicate a compressor malfunction. Most refrigerators in today’s homes have a silent compressor, so any noise is a sign of an issue.
Inadequate cooling: While this symptom can be caused by other factors, sudden temperature change might be due to a broken compressor.
Fan malfunction: If the fridge compressor has a broken fan, it may be impacting coolant circulation. The fan can also overheat, negatively impacting temperature regulation.
Control board failures: Water-damaged control boards can lead to significant compressor failures.
Refrigerant vapor odor: A chemical-like or burning smell could indicate a coolant leak. If addressed immediately, the fridge can return to function and keep food cool.
Overheating gas line: If the fridge is hooked to a gas line, it can also become too hot and prevent effective cooling.
Dirty condenser coils: If the coils on the condenser are dirty, it can cause the compressor to overheat and fail. These coils should be cleaned regularly to prevent this issue.
Cycling Issues: Constant cycling on and off may indicate problems with the compressor start relay.
As soon as homeowners recognize any of these symptoms, it’s essential to contact a refrigerator repair technician for help restoring compressor function. While problems with refrigerator compressors can be frustrating, they’re generally simple and quick for professionals to fix.
Completing regular maintenance
Prevent compressor problems (and other refrigerator issues) by servicing the fridge regularly. This should include deep cleaning, checking seals and gaskets, and ensuring all parts are functional. This maintenance should be completed every few months.
Deciding between replacement and repair
If a compressor continuously malfunctions, it may be time to consider replacement. While symptoms like excessive humming noise, uneven cooling, and on/off cycles may seem like just a nuisance, the compressor may no longer be functional and should be replaced before more damage is sustained.
Homeowners who have a bad compressor may be able to hold off on replacing the fridge, and just replace the compressor instead. The average cost of replacing an old compressor is around $300, depending on the refrigerator make and model. On the other hand, a brand new refrigerator costs an average of $1,200. It is a good idea to call a professional to complete an inspection and provide recommendations on whether or not repair or replacement is the best option.
Regular maintenance, appropriate preventive measures, and prompt, professional service are vital in maintaining the longevity and efficiency of refrigerator compressors. Call a trusted professional as soon as issues arise to keep food cold and fresh!
