What causes bad refrigerator compressor noise? Failing overhead protectors, and power compressors, etc. causes the refrigerator compressor to produce loud rattling or vibrating noises which can be very unpleasant.
Healthwise, when you get exposed to these noises for an extended period, you could suffer hearing loss or temporary hearing damage whereby you feel like your ears are stuffed up. Investment wise, these unpleasant sounds could be signs of a failing refrigerator compressor which when not corrected on time would lead to the machine incurring significant damages.
To help you fix this issue, lets first begin with understanding what causes the refrigerator compressor noise.
Bad Refrigerator Compressor Noise - Extend the Lifetime of Your Fridge
1. Failing Fan-Cooled Condenser
If you're using a modern frost-free refrigerator, the cause of those strange noises could be a failing fan-cooled condenser. It's usually located in the rear region of the fridge at the lower part. It works by circulating air over a drain pan, so the defrost water can evaporate.
It also works with the condenser coil to circulate and cool air. When the refrigerator compressor makes strange noises, the condenser fan motor which operates together with the evaporator motor could be failing. Apart from the sounds, it could also be impacting your refrigerator's cooling ability.
2. A Faulty Evaporator Fan Motor
This component is found in the freezer region of your appliance. Its role is to withdraw air over the evaporator when the compressor is in operation. When it begins to fail, it also degrades your refrigerator's ability to cool air.
Now, if the noise is emanating from the freezer region, the cause could be a damaged or loose fan blade. The strange noises would also be due to the motor not turning freely.
3. Worn Out Evaporator Fan Motor Grommet
The role of the evaporator fan motor grommet is to separate the motor from monitor bracket to minimize noise due to vibration. When used for an extended period, it begins to wear out and would finally detach. A worn out or detached evaporator fan motor grommet cannot effectively separate the motor from the monitor bracket, hence the intense vibrations, and noises.
Refrigerator Compressor Repair, And Maintenance
To solve all these issues, you'll need to unplug the appliance to access the affected regions then remove obstructions, and fix the loose parts or replace the worn out components, etc.
While some of these functions like removing dirt which obstructs the evaporator pan can easily be done at home by you, there are some sensitive operations which requires qualified servicemen's intervention.
In solving these complications, the repairmen will not only correct the faults but also propose to you some maintenance tips to keep the refrigerator in good condition. A reputable service and repair agency should perform an extensive check, and identify other minor faults which could lead to primary damage to the equipment.
In Conclusion
In case you're having doubts about the causes of bad refrigerator compressor noise, you should reach out to a professional. They will help you by assessing the machine to diagnose the fault and repair it for you. They will also answer any questions you may have about your machine's functionality, and give you valuable tips on how to make it stand the test of time.
