Why Won’t My Air Conditioner Turn Off?

Possible Reasons Why Your AC Is Not Turning Off

The issue with your HVAC unit can be linked to several underlying problems such as haywire in electrical connections, dirty air filters, a frozen coil of the evaporator, and many more.

Here is a list of situations that should be taken into account.

Fault in The Thermostat

As your air conditioner ages with time, the internal system shows signs of malfunction. As a result, the thermostat accumulates a greasy substance which prevents it from circulating the air evenly. It needs to be changed every 8-10 years to perform swiftly. Or else, this dirt will act as a block between the thermostat and ac.

Condenser Coils are Dirty and Clogged

Before reaching the condenser, air passes through the evaporator coil and refrigerant pipeline. It often leaves residues of dirt and grease inside the coils. It stops the condenser from releasing the heat from the pipeline, preventing the ac from functioning properly.

The Switch Fan is not Operating Properly

Even when you have switched off the air conditioner, it might still run. Obstruction in the fan switch, when it is in the override position, can cause such a situation.

The Speed of The Fan is Declining

The speed of your fan is proportional to cool air. It means that if the fan runs at a nominal speed, your room will be more airy and cool. If your air cooling system takes a considerable amount of time to cool the room, the reason should directly link to the fan’s speed. Dirt and debris sticking onto the fan can be a reason for such a decline in speed.

Disturbance in The Electrical Connection

Every electrical device comprises several circuits interconnected to give you the utmost performance. A relay switch is responsible for operating and controlling the power. A fuse inside one of the circuits will allow the air conditioner to run continuously.

Air Filters are Dirty

Dirty air filters are not good for health. Are you also aware that it can create technical problems in the device? Filters can be accumulated with dust particles in different ways. It can also make the system run continuously even after turning the switch button off.

Icy Evaporator Coils

Evaporator coils can get frozen due to the build-up of dirt inside the coils, obstruction in the vent, or untidy air filters. It can cause the heat to stay inside the device.
