The refrigerator compressor is the heart of your appliance, responsible for circulating refrigerant and keeping your food cool. When it starts failing, your fridge may not work as efficiently, leading to spoilage, higher energy bills, or even total breakdown. Knowing the signs your refrigerator compressor is failing can help you catch the issue early and save money on repairs or replacement. In this guide, we’ll walk through the key signs and DIY fixes homeowners can try before calling a technician.
1. Loud Noises from the Compressor
One of the most common signs your refrigerator compressor is failing is unusual noise. If you notice loud humming, knocking, or clicking sounds, the compressor may be struggling.
How to Fix It:
- Check for loose parts: Sometimes, the noise is due to loose components. Tighten any screws or bolts.
- Clean the compressor: Dirt and dust can block airflow, causing noise. Use a vacuum or soft brush to clean the area.
- Call a professional: If the noise persists, it could indicate motor failure, which requires professional repair.
2. Compressor Running Constantly
A properly functioning compressor cycles on and off. If you notice your fridge running non-stop, this is a clear sign something is wrong.
How to Fix It:
- Check the thermostat settings: Make sure the fridge and freezer temperatures are set correctly.
- Clean the condenser coils: Dusty coils force the compressor to overwork. Clean them using a vacuum or coil brush.
- Inspect the door seals: If the door doesn’t seal tightly, cool air escapes, causing the compressor to overwork. Replace any worn seals.
3. Fridge Isn’t Cooling Properly
If your food isn’t staying cold or takes longer than usual to cool, your compressor may be failing. This could be due to refrigerant leaks or a compressor that’s losing efficiency.
How to Fix It:
- Check the evaporator fan: If the fan isn’t working, cool air won’t circulate properly. Replace it if needed.
- Inspect for leaks: Look for oil spots around the compressor, which may indicate a refrigerant leak. In this case, it’s best to call a professional.
- Test the temperature control: Use a thermometer to confirm the fridge’s internal temperature. If it’s consistently warm, the compressor may need replacing.
4. Overheating Compressor
The compressor should be warm, but if it becomes too hot to touch, this is a warning sign. Overheating can lead to motor burnout.
How to Fix It:
- Improve airflow: Ensure the fridge is placed in a well-ventilated space with adequate clearance around the compressor.
- Clean the fan: Dust or debris in the fan can lead to poor airflow. Clean or replace it if needed.
- Unplug and cool down: If the compressor overheats, unplug the fridge and let it cool down for a few hours before restarting.
5. Higher Electricity Bills
A failing compressor can cause your refrigerator to consume more energy, leading to higher electricity bills. If you notice a sudden spike in your energy usage, the compressor could be to blame.
How to Fix It:
- Inspect the compressor: Check for signs of strain such as loud noises or overheating. Address these issues immediately.
- Replace worn components: Replacing old or worn components like the fan motor or thermostat can help reduce energy consumption.
- Schedule a maintenance check: If the problem persists, contact a technician to perform a thorough inspection and repair.
6. Compressor Shutting Off Too Soon
If your compressor shuts off too soon after starting, it may be due to a relay failure or overheating.
How to Fix It:
- Check the start relay: If the relay is faulty, the compressor won’t start properly. Test it using a multimeter and replace it if necessary.
- Inspect for overheating: As mentioned earlier, overheating can cause the compressor to shut down prematurely. Ensure proper ventilation and clean the fan.
- Call a professional: If the compressor still doesn’t stay on long enough, it may need to be replaced.
7. Leaking Refrigerant
A refrigerant leak can cause the compressor to lose efficiency, leading to cooling problems and potentially damaging the entire system.
How to Fix It:
- Look for leaks: If you notice oil or refrigerant around the compressor, it’s likely that a leak is present. This should be handled by a professional, as refrigerant can be hazardous.
- Avoid DIY fixes for leaks: Refrigerant leaks require specialized tools and knowledge. Call a licensed technician for repairs.
8. Unusual Smells
If you notice a burning smell or any unusual odors coming from your refrigerator, the compressor may be burning out or there could be an electrical issue.
How to Fix It:
- Unplug the fridge immediately: Electrical issues can be dangerous. Unplug the appliance and avoid using it until it’s inspected.
- Inspect wiring and components: Check for visible damage to the wiring or electrical components. Replace damaged parts if you’re confident in your skills, or call a technician.
- Get professional help: Burning smells are often a sign of major electrical faults. Contact a repair expert as soon as possible.
