What are common causes for a fridge working but not cooling?
One of the most common causes for a fridge that is running but not cooling properly can be a malfunctioning thermostat. The thermostat is responsible for regulating the temperature inside your fridge, and if it’s faulty or incorrectly set, it can prevent the compressor from running when needed, leading to inadequate cooling.
Another possible reason is a blocked air vent. Proper air circulation is crucial for maintaining the right temperature. If the vents inside the fridge become obstructed by food items or frost build-up, cold air may not adequately circulate throughout the appliance, causing it to feel warm even though it’s powered on.
How can I tell if the compressor is the problem?
To determine if the compressor is the issue, listen for unusual sounds coming from the fridge. A clicking noise or a complete lack of noise could indicate that the compressor is stuck or malfunctioning. Additionally, check if the compressor is hot to the touch; if it is overheating, this is a sign that it may not be functioning properly.
You can also inspect the compressor’s start relay—this small device is responsible for turning the compressor on and off. If the relay appears burnt or damaged, it may prevent the compressor from functioning effectively. If you’re unsure, it’s best to consult a professional to diagnose and repair the issue.
What should I do if there’s frost build-up in my freezer?
Frost build-up in your freezer can impede airflow and cause cooling issues. To address this problem, you should first unplug the fridge and allow the frost to melt completely.
