Sometimes we notice our fridge running nonstop, humming away without taking a break. This can be frustrating because it usually signals a problem that needs attention. We want our fridges to cool properly while also saving energy. If the appliance never cycles off, it could mean wasted electricity, higher bills, or food safety risks. In this post, we will look at the most common causes, what we can do to solve them, and when to call for help. At Freedom Appliances, we handle these issues every day and can share practical steps that actually work.
Dirty or Blocked Condenser Coils
One common reason a fridge keeps running is dirty condenser coils. These coils release heat, and when dust builds up, the fridge struggles to stay cool. As a result, the compressor runs almost nonstop. We can usually find these coils either on the back or underneath the fridge.
Cleaning them with a coil brush or vacuum often makes a huge difference. It is important to unplug the unit before doing this. We should also make coil cleaning part of regular maintenance. For homeowners looking for more detailed troubleshooting, our guide on Calgary refrigerator repair services covers advanced steps and when to involve a professional.
Faulty Door Gaskets
Another issue that often causes nonstop running is worn or faulty door gaskets. When the rubber seals are damaged, warm air sneaks inside. Consequently, the fridge keeps working to lower the temperature. Checking the gasket for cracks, tears, or looseness can reveal the problem.
We can test it by placing a piece of paper between the seal and door, then pulling it out. If it slides out too easily, the seal may need replacing. Installing new gaskets is a straightforward fix, but it should be done carefully so the door closes evenly. If ignored, this small problem quickly becomes costly because of wasted energy and food spoilage.
Incorrect Temperature Settings
Sometimes the fix is as simple as adjusting the thermostat. If the temperature is set too low, the fridge will never cycle off. We often think colder is safer for food, but that is not always true. The ideal range is 37 to 40 degrees Fahrenheit for the fridge and zero for the freezer.
We should check with an appliance thermometer rather than relying only on the built-in dial. After making adjustments, it may take several hours to see a change. Setting temperatures correctly not only saves energy but also extends the life of the compressor. This simple step prevents a lot of unnecessary service calls.
Problems with the Evaporator Fan
Inside the fridge, the evaporator fan circulates cool air. If it fails or gets blocked by ice, cooling becomes uneven. As a result, the compressor stays on longer than it should. We may also hear strange noises coming from the freezer section.
Defrosting the freezer fully often solves ice buildup problems. If the fan motor itself is worn out, replacement is usually required. This type of repair is best handled by professionals since it involves working inside the cooling system. Still, recognizing the signs helps us decide if service is needed before food spoils.
Overloading and Poor Airflow
The way we store food can also cause trouble. Packing the fridge too tightly blocks vents and reduces circulation. The compressor then works overtime trying to cool all areas evenly. On the other hand, running a nearly empty fridge can also cause issues because there is less thermal mass to maintain steady temperatures.
We should keep shelves organized, leaving space around vents and ensuring containers are not pressed against the back wall. A balanced fridge runs more efficiently and cycles off as it should. Managing airflow is one of the easiest habits we can adopt to keep energy use under control.
Defrost System Failures
Modern fridges are designed to defrost automatically, but when this system fails, frost builds up around coils. That frost acts like insulation, preventing proper heat exchange. The compressor then keeps running to make up for the lost efficiency.
Checking for frost buildup on the back panel of the freezer can give clues. If it looks like a sheet of ice, the defrost heater, timer, or sensor may be faulty. This repair requires more than basic tools, so most people should schedule professional service. If left alone, the fridge will eventually stop cooling properly altogether.
Malfunctioning Thermostat or Control Board
When mechanical or electronic controls fail, the fridge loses its ability to regulate cycling. A faulty thermostat may not signal the compressor to turn off. Similarly, a control board issue may disrupt timing altogether. These problems are harder to diagnose without experience.
If we have already tried cleaning coils, checking gaskets, and adjusting temperatures, the next step often involves testing controls. Since this requires electrical knowledge, it is usually safer to reach out for expert help. Our team at Freedom Appliances specializes in diagnosing these kinds of hidden issues and repairing them effectively. For more support, you can explore our services for appliance repair in Calgary.
When to Call for Professional Help
Some tasks like cleaning coils or rearranging food are easy for us to handle. However, issues with wiring, fans, or sealed system parts are not do-it-yourself jobs. Calling for help at the right time can prevent bigger and more expensive breakdowns.
We should also consider safety. Refrigerant leaks, electrical shorts, or failing compressors all pose hazards if handled incorrectly. In these cases, scheduling service quickly ensures our fridge is repaired safely and correctly. If you notice constant running even after trying the common fixes, it is time to let an expert take over.
Preventive Maintenance Tips
The best way to avoid nonstop running is to build simple habits into our routine. Cleaning coils twice a year, checking gaskets regularly, and organizing food properly all keep the fridge working efficiently. We should also avoid leaving the door open for long periods, especially in warmer months.
Adding a thermometer inside both compartments is an inexpensive way to keep track of temperatures. By staying proactive, we prevent small issues from becoming major breakdowns. When in doubt, scheduling a quick inspection with professionals gives us peace of mind and keeps our appliances in top shape. For immediate support, reach out through our contact us page.
FAQs
Why does my fridge never shut off even when it feels cold?
This often happens because controls are not signaling the compressor to stop. It could be a thermostat issue or blocked coils.
How often should I clean refrigerator coils?
We recommend cleaning them twice a year, more often if you have pets since hair and dust build up quickly.
Can a fridge that runs constantly still keep food safe?
Yes, but it uses more energy and may eventually wear out. Food may also freeze in the fridge section if the temperature is too low.
Is it normal for a new fridge to run all the time?
Sometimes yes, especially in the first day or two as it stabilizes. If it continues after that, a problem may be present.
Should I unplug my fridge if it is running constantly?
No, do not unplug it. Instead, check simple things like settings, gaskets, and coils, then call for service if needed.
