Your refrigerator is a key appliance in your home, keeping food fresh and safe. However, when the compressor starts to fail, your refrigerator can lose its cooling efficiency, which could lead to spoiled food and wasted energy. It’s essential to identify the early signs your refrigerator compressor is failing so that you can take action before the situation worsens.
This guide will walk you through the most common symptoms of a failing compressor and how you can fix it with simple step-by-step instructions. Acting fast can prevent further damage and help you save on expensive repairs or replacements.
Common Signs Your Refrigerator Compressor Is Failing
The compressor is the heart of your refrigerator, responsible for circulating refrigerant and maintaining the cooling cycle. When it starts to malfunction, several key indicators can signal that your refrigerator compressor is not working as it should.
Refrigerator Not Cooling Properly
One of the most obvious signs that your compressor is failing is when the refrigerator isn’t cooling as effectively as it once did. You might notice that your food is spoiling faster than usual, or that the interior temperature feels warmer than it should.
This happens because the compressor isn’t able to circulate refrigerant efficiently, resulting in reduced cooling power.
Unusual Noises from the Compressor
Another common symptom is a refrigerator compressor that is noisy. If you start hearing loud knocking, humming, or clicking sounds coming from the back of your fridge, this could indicate a problem with the compressor’s internal components.
A compressor that makes excessive noise might be overworking or on the verge of failure. These noises often worsen over time, so if you hear them, it’s time to inspect the compressor.
Compressor Running Too Often
While it’s normal for the compressor to cycle on and off throughout the day, if you notice that it’s running constantly without breaks, this could mean trouble. A failing compressor might struggle to maintain the desired temperature, leading to overuse and eventual burnout.
Overheating of the Compressor
Feel the back of your refrigerator where the compressor is located. If it’s unusually hot to the touch, this can be a warning sign. An overheating compressor can be the result of faulty wiring, a refrigerant leak, or a failing motor.
Refrigerator Leaking Refrigerant
A refrigerant leak is another sign that the compressor is not functioning correctly. If you notice a strange, oily liquid pooling under your fridge, this could be refrigerant. Without proper refrigerant levels, the compressor can’t maintain the correct cooling levels, leading to spoilage.
Refrigerator Tripping Circuit Breaker
If your refrigerator is tripping the circuit breaker, this could point to an electrical issue with the compressor. A faulty compressor can draw too much power, causing electrical overloads that trip the breaker repeatedly.
How to Fix a Failing Refrigerator Compressor
Once you’ve identified the signs your refrigerator compressor is failing, you can try to address the issue with these step-by-step instructions. If the problem persists, it may be time to call a professional technician.
Step 1: Unplug the Refrigerator
- Before attempting any repairs, always unplug the refrigerator to ensure safety. Working with electrical components while the appliance is powered can be dangerous.
Step 2: Clean the Compressor Area
- Dust and debris can accumulate around the compressor over time, causing it to overheat or function improperly. Use a vacuum cleaner or a soft cloth to clean the area thoroughly, especially around the coils and vents.
Step 3: Check the Compressor Relay
- The compressor relay helps the compressor start. A faulty relay can prevent the compressor from operating correctly. You can test it by unplugging the refrigerator, locating the relay (typically next to the compressor), and using a multimeter to check for continuity.
- If the relay is faulty, replace it with a new one.
Step 4: Test the Capacitor
- The capacitor works alongside the compressor to regulate the start-up process. A defective capacitor can cause the compressor to fail. Test the capacitor with a multimeter, and if it’s faulty, replace it.
Step 5: Inspect the Refrigerant Levels
- Low refrigerant levels can strain the compressor. While this step typically requires a licensed technician, checking for refrigerant leaks and refilling the system can restore your compressor’s efficiency.
Step 6: Replace the Compressor
- If all else fails, the compressor may need to be replaced entirely. This is a complex and costly procedure that requires professional assistance. A technician will need to discharge the refrigerant, remove the old compressor, install a new one, and recharge the refrigerant.
Wrap-up
The signs your refrigerator compressor is failing are important to recognize early on to avoid more extensive and expensive repairs. From poor cooling to strange noises, catching these signs early can prevent further damage to your refrigerator. While some fixes, like cleaning the compressor or testing the relay, can be done at home, others may require professional help.
