The most common reasons AC won’t turn on

It’s common for homeowners to experience a problem with their ac unit occasionally. Before you rush to avail the services of an HVAC technician, follow the steps outlined below to identify and solve the problem.

Faulty motors:

Have you heard the unusual sounds before the unit stopped working altogether? If yes, then it is more likely the issue lies on the motor. To be surer, do a capacitor test to find out whether the problem is actually with the motor or not.

Faulty compressors:

The defective or broken compressor often makes the air conditioner to shut down. Timely cleaning and maintenance can go a long way to help prevent these problems.

The thermostat needs to be replaced:

A broken or outdated thermostat that either needs a battery or has some other technical fault can immediately stop the ac from turning on. If you have the basic knowledge for HVAC, you can conveniently identify the issue by yourself or go through the various settings of the Thermostat to make sure it works properly.

Dirty condenser lines:

Condenser lines that have mold, algae grown-up can sometimes be a reason for the air conditioner's sudden breakdown. The AC condenser unit is generally outside the home, and you can clean all the mess inside with white vinegar.

The fuse is not working:

You can do a continuity test with a multimeter to find out whether the fuse is working correctly or not. If you hear no beep in the multimeter, then the reason behind AC not turning is: “blown fuse”.

Tripped circuit breaker:

When there is a massive electricity overload, it is very likely for the circuit breaker to trip and interrupt the power flowing. The reason behind breakers tripping can be using too many appliances at the same time or having outdated equipment that consumes more electricity.
