Your refrigerator might be running constantly due to a dirty condenser coil, low refrigerant levels, or a faulty thermostat. Check these common issues to improve efficiency and save energy!
Have you ever wondered, “Why is my refrigerator running constantly?” It might not be a problem at all! Refrigerators typically cycle on and off to maintain their cold temperature. For example, a 500-watt refrigerator usually consumes only 150 to 175 watts. However, if it is running constantly, there may be an underlying issue.
Top Highlights
- Warm rooms and opening the fridge often make it run longer. Keep the door shut and the room cool to save energy.
- Cleaning coils and checking seals can stop overworking and save power. Clean the coils twice a year for best results.
- If your fridge keeps running after cleaning, check for broken parts or clogged vents. Call an expert if the problem doesn’t go away.

Why Is My Refrigerator Running Constantly? Normal Reasons
High ambient temperature
Does your fridge run more in summer? That’s normal. When it’s hot, your fridge works harder to stay cool. It’s like how we sweat to stay comfortable in heat. Newer fridges with variable speed compressors handle heat better. NEEA says these compressors save 10-30% energy. They don’t turn on and off as much. Instead, they adjust to the heat efficiently. So, if it’s hot and your fridge runs a lot, it’s just doing its job.
Frequent door openings
Do you open the fridge often to decide on food? I do too! Each time the door opens, warm air gets inside. The fridge then works harder to cool down again. If kids or guests open it often, it will run more. Try keeping the door closed as much as you can. This helps your fridge and saves energy too.
Variable speed compressors designed for energy efficiency
Not all fridges are the same. Some newer ones have variable speed compressors. These don’t turn on and off all the time. Instead, they change speed to keep the temperature steady. They may run more but use less energy overall. NEEA says these compressors work better in heat. If your fridge runs constantly and has this feature, it’s being energy-efficient.
Why Is My Refrigerator Running Constantly? Common Issues
Sometimes, when a refrigerator runs constantly, it’s not just working harder—it’s signaling a problem. Let’s dive into some common culprits that might be causing this issue.
Dirty condenser coils
Have you ever looked at the back or bottom of your fridge? That’s where the condenser coils live. These coils release heat, but when they’re covered in dust or grime, they can’t do their job properly. The fridge has to work overtime to stay cool, which means it runs constantly. I’ve seen this happen in my own kitchen, and trust me, cleaning those coils made a huge difference.
- Dirty coils can lead to higher electricity bills and even shorten your fridge’s lifespan.
- A quick clean every six months can prevent this problem. Just unplug the fridge, grab a coil brush or vacuum, and get to work!
Faulty defrost thermostat
The defrost thermostat keeps frost from building up on the coils. When it stops working, frost can take over, blocking airflow and making the fridge run non-stop. I’ve read that this is a pretty common issue, and it’s one you don’t want to ignore. If you notice frost buildup, it might be time to test or replace the thermostat.
- Frost buildup restricts airflow, forcing the fridge to run constantly to maintain the right temperature.
- A faulty defrost thermostat is often the hidden culprit behind this issue.
Damaged or worn door gaskets
The door gaskets are those rubber seals around the fridge door. They keep the cold air in and the warm air out. If they’re cracked, loose, or worn out, your fridge has to work harder to stay cool. I always check mine by closing the door on a piece of paper. If the paper slides out easily, it’s time to replace the gaskets.
- Damaged gaskets let warm air in, causing the fridge to run more than it should.
- Replacing them is a simple fix that can save energy and extend your fridge’s life.
Incorrect temperature settings
Did you know that setting your fridge too cold can make it run constantly? I didn’t until I checked my own settings. The ideal temperature for a fridge is between 37°F and 40°F. If it’s set lower, the fridge will keep running to maintain that unnecessary chill.
- A fridge running constantly might just need a quick adjustment to its temperature settings.
- Always double-check the settings if you notice your fridge working overtime.
Blocked air vents or improper airflow
Air needs to circulate freely inside the fridge to keep everything cool. If vents are blocked by food or containers, the fridge can’t do its job efficiently. I’ve made this mistake before—overloading the fridge and wondering why it’s running all the time.
- Blocked vents disrupt airflow, making the fridge work harder.
- Keep vents clear and avoid overpacking the fridge to ensure proper airflow.

Malfunctioning condenser fan motor
The condenser fan motor helps cool the compressor and condenser coils. If it’s not working, the fridge can overheat and run constantly. I’ve heard that a noisy or silent fan is often a sign of trouble. If you suspect this issue, it’s best to inspect the fan and replace it if needed.
- A malfunctioning fan motor can lead to overheating and constant running.
- Regular maintenance can help catch this problem early.
Weak or failing compressor
The compressor is like the heart of your fridge. It pumps refrigerant through the system to keep things cool. If it’s weak or failing, the fridge will struggle to maintain the right temperature and run non-stop. Unfortunately, a failing compressor often requires professional repair or replacement.
- A weak compressor is a serious issue that can’t be ignored.
- If you’ve tried everything else and the fridge still runs constantly, it might be time to call in a pro.
Tip: Regular maintenance can prevent many of these issues. Cleaning the coils, checking the gaskets, and keeping the fridge organized can go a long way in keeping it running smoothly.
Troubleshooting a Constantly Running Refrigerator
If your refrigerator is running constantly, don’t panic! I’ve been there, and with a little troubleshooting, you can often fix the issue yourself. Let’s walk through some steps to get your fridge back to normal.
Cleaning the condenser coils
When was the last time you cleaned the condenser coils? If you’re like me, it’s probably been a while. Dirty coils make it harder for the fridge to release heat, so it keeps running to stay cool. Cleaning them is easier than you think.
Here’s what I do:
- Unplug the fridge for safety.
- Use a coil brush or vacuum to remove dust and debris.
- Plug it back in and see if it runs less.
I try to clean mine every six months. It’s a small task that makes a big difference in energy efficiency.
Inspecting and replacing door seals
Have you checked the door seals lately? Those rubber gaskets around the door keep the cold air in. If they’re damaged or dirty, warm air sneaks in, and the fridge works overtime.
I like to test the seals with a simple trick. Close the door on a piece of paper. If the paper slides out easily, the seal isn’t tight enough. Cleaning the seals with warm, soapy water can help. If they’re cracked or worn, replacing them is the best option. It’s a quick fix that saves energy and keeps your fridge running smoothly.
Testing the defrost system
A faulty defrost system can cause frost to build up on the coils, blocking airflow. When this happens, the fridge runs constantly to maintain the right temperature. I’ve learned that testing the defrost thermostat and heater can help identify the problem.
If you’re comfortable with DIY repairs, you can use a multimeter to test these components. If not, it might be time to call a professional. Either way, addressing this issue promptly can prevent further damage.
Adjusting temperature settings
Did you know that incorrect temperature settings can make your fridge run non-stop? I didn’t until I checked mine. The ideal setting is 37℉ for the fridge and 0℉ for the freezer. If it’s set too low, the fridge works harder than it needs to.
Adjusting the settings is simple. Most fridges have a dial or digital control panel. Once you set it to the right temperature, give it a day to stabilize. You’ll likely notice a difference in how often it runs.
Ensuring proper airflow inside the refrigerator
Overloading the fridge can block air vents and disrupt airflow. I’ve made this mistake before, cramming too much food inside and wondering why my fridge wouldn’t stop running.
Now, I make sure to leave some space around the vents. Proper airflow helps maintain an even temperature and reduces the workload on the fridge. It’s also a good excuse to declutter and get rid of expired items!
Checking the condenser fan motor
The condenser fan motor cools the compressor and condenser coils. If it’s not working, the fridge can overheat and run constantly. I’ve noticed that a noisy or silent fan is often a sign of trouble.
To check the fan, I unplug the fridge and locate it near the back or bottom. If it’s dirty, cleaning it might solve the problem. If it’s damaged, replacing it is usually the best option. A functioning fan motor is essential for keeping your fridge running efficiently.
Tip: Regular maintenance, like cleaning the coils and checking the seals, can prevent many of these issues. It’s a small effort that goes a long way in keeping your fridge in top shape.
