How to Tell if Your Refrigerator Compressor Is Bad
Signs, Causes, and SolutionsWhy Your Refrigerator Isn’t Cooling: Symptoms of Compressor Malfunctions
Your refrigerator is a crucial appliance in your home, working 24/7 to keep your food fresh and safe. At its heart is the compressor, which is responsible for the refrigeration process. However, like all mechanical components, compressors can fail over time due to various reasons. Recognizing the signs of a failing compressor early can help prevent further damage and more expensive repairs. This article provides an in-depth guide on how to identify if your refrigerator’s compressor is bad, common causes of compressor failure, and answers to frequently asked questions.
What Is the Most Common Cause of Refrigerator Compressor Failure?
Refrigerant Issues: The most common cause of compressor failure is related to refrigerant issues. This could involve leaks, contamination (like moisture entering the refrigerant system), or an improper amount of refrigerant. These issues make it difficult for the compressor to function properly, leading to failure.
Common Causes of Refrigerator Compressor Failure
Refrigerant Leaks:
A leak in the refrigerant line reduces the refrigerant levels, causing the compressor to overheat. Leaks should be repaired and refrigerant recharged by a professional.
Dirty Condenser Coils:
Accumulation of dirt and dust on the condenser coils makes it harder for the compressor to expel heat, leading to overheating and failure.
Power Surges:
Electrical surges can damage the compressor or its components, leading to failure.
Wear and Tear:
Over time, the compressor components may naturally wear out, especially in older models, leading to inefficiency or complete failure.
Refrigerator Compressor Failure Symptoms
- Increased noise from the compressor: Unusual noises like humming, buzzing, or clicking can indicate the compressor is struggling.
- Frequent cycling: The refrigerator runs non-stop or cycles on and off too frequently.
- Warm food: If your refrigerator is not keeping your food cool enough, even when set to the correct temperature, the compressor may be malfunctioning.
- High electricity bills: A compressor that is not functioning properly will draw more power, leading to higher energy costs.
- Hot compressor: An overly hot compressor may indicate it’s under strain and close to failure.
How to Diagnose and Fix a Failing Refrigerator Compressor
1. Listen for Unusual Noises
The first thing to check is if your refrigerator is making louder than normal sounds. A loud hum, buzz, or clicking noise can indicate a failing compressor.
2. Check Temperature Consistency
If the fridge isn’t keeping food cool enough, check the thermostat settings and clean the condenser coils. If these don’t resolve the issue, the compressor might need a professional assessment.
3. Inspect for Heat:
Feel the compressor for excessive heat, especially after it’s been running for a while. A hot compressor is a sign it’s working harder than it should.
4. Test the Start Relay
The start relay can often be replaced more easily and inexpensively than the compressor. If it’s failing, the compressor might not start or could turn off unexpectedly.
5. Call a Technician:
If you notice any of these signs, it’s crucial to consult a professional. Repairing or replacing a compressor involves handling refrigerants, which can be dangerous without proper training and equipment.
5 Signs That Your Refrigerator Compressor Might Be Failing

What to Check
How to Fix
Brand Examples
1. Your Refrigerator Is Always Running
Your refrigerator is running continuously without cycling off, even after a few hours. This suggests that the compressor is struggling to maintain the internal temperature, which also causes higher energy consumption.
What to Check:
- Ensure that the vents inside the fridge are not blocked by food, and inspect the door seals for leaks. Also, confirm the thermostat setting is correct. If these are in order, the compressor may be at fault.
How to Fix:
- If there’s no blockage or seal issues, and the fridge still isn’t cooling, it’s time to call a professional to inspect and possibly repair or replace the compressor.
Brand Examples:
- This problem can occur with Samsung, Whirlpool, and LG models, especially when the compressor is not maintaining the correct cooling cycle.
2. You Hear Unusual Noises
If the compressor is making strange sounds such as grinding, clicking, or buzzing loudly, it could be a sign that the motor is struggling or components inside the compressor are malfunctioning.
What to Check:
- Listen for a loud hum or a clicking sound. Check if the noise is coming from the compressor area, typically located at the back or bottom of the fridge.
How to Fix:
-
Unusual noises often indicate an internal issue with the compressor. This usually requires a professional technician to assess and repair the compressor or replace faulty internal components.
Brand Examples:
- Common brands where this issue occurs include GE and LG, which are known for experiencing compressor-related noise problems, especially as they age.
3. The Compressor Is Hot to the Touch
If the compressor feels extremely hot when touched, this could indicate that it is working too hard to maintain the temperature or that internal components are malfunctioning, leading to overheating.
What to Check:
-
Feel the compressor after the fridge has been running for a while. A small amount of heat is normal, but excessive warmth suggests a problem.
How to Fix:
- An overly hot compressor may need to be repaired or replaced. This could be due to insufficient refrigerant, a failing motor, or an issue with the start relay. Professional repair is needed to diagnose and fix this issue.
Brand Examples:
- Overheating compressors are common in GE, Frigidaire, and LG refrigerators, particularly when the compressor is under excessive strain due to wear.
4. Your Circuit Breaker Keeps Tripping
If your refrigerator causes the circuit breaker to trip regularly, it indicates that the compressor is drawing too much power, which often happens when it is failing or under stress.
What to Check:
-
Check if the breaker trips whenever the refrigerator starts up. This could be a sign that the compressor is failing and drawing more current than it should, causing an overload.
How to Fix:
- This is a serious issue that requires immediate professional attention. The compressor might need to be repaired or replaced, as continued operation could lead to further electrical damage or safety hazards.
Brand Examples:
- This issue can be found in Samsung, Frigidaire, and Whirlpool refrigerators, which sometimes experience electrical problems when the compressor is overworked.
5. The Fridge Isn’t Cool Enough
The fridge is not cooling properly, and food is spoiling faster than usual. Even though the thermostat is set to the correct temperature, the fridge still feels warm.
What to Check:
-
Ensure that the vents inside the fridge are not blocked by food, and inspect the door seals for leaks. Also, confirm the thermostat setting is correct. If these are in order, the compressor may be at fault.
How to Fix:
- If there’s no blockage or seal issues, and the fridge still isn’t cooling, it’s time to call a professional to inspect and possibly repair or replace the compressor.
Brand Examples:
- This problem can occur with Samsung, Whirlpool, and LG models, especially when the compressor is not maintaining the correct cooling cycle.
Recognizing the signs of a failing refrigerator compressor is essential for maintaining your appliance’s efficiency and preventing further damage. If you suspect your refrigerator’s compressor is bad, it’s best to consult with a professional appliance repair technician. They can safely diagnose and fix issues, ensuring your fridge continues to operate at its best.
