Why does my fridge keep running?
5 most likely reasons your fridge is constantly running 1 Door gasket - worn out gaskets tend to be the biggest reason why your compressor runs non-stop. When your gaskets are worn out or warped, the gaps allow warmer, more humid air to travel through them. The compressor has to run more often to cool down that warm air and maintain the proper temperature setting. We recommend that this be the first item you check when troubleshooting a fridge that runs constantly. 2 Dirty condenser coils - these coils are usually found at the bottom of the fridge. Their purpose is to condense the gas refrigerant into a hot liquid. As the gas is converted to liquid and travels through the coils, the excess heat is dissipated through the coils. The problem arises when the coils become covered with hair, dirt, and other debris that collects over time. Because the condenser coils cannot dissipate heat efficiently nor properly, the compressor will end up running constantly in an effort to cool the individual elements.
Why does my fridge compressor kick on?
Amount of time the door remains open - every time your fridge door is opened, it allows warmer (sometimes more humid) air to enter. This causes your compressor to kick on more frequently and for a longer duration as it has to compensate for the sudden change in temperature .

Why does my refrigerator door leak?
The door of your refrigerator has a gasket around it which helps seal the food compartment so that the cold air outside cannot escape . However, due to age or improper maintenance, the adhesive keeping the gasket glued to the door’s edge may start to come off. The result is improper seal being created when the refrigerator is closed, and cold air escaping through the resulting leaks. This means that in order to maintain the internal temperature of the refrigerator to the set thermostat value, the compressor will need to cycle constantly. To correct the issue, replace the rubber gasket around the door as soon as possible.
How does a refrigerator thermostat work?
This works like the eyes of your refrigerator, letting it know when to start and when to stop, so that the temperature inside is maintained at a constant value preset by you.
