Common Reasons Your Air Conditioner Is Not Turning On

With the weather getting warmer by the day, people are finding it difficult to stay indoors without turning on their air conditioning systems. If your air conditioner refuses to turn on in this scorching heat, it can be a major cause of worry for your whole family. However, no need to panic because air conditioners not turning on is not an uncommon problem. Read on to learn about the steps to identify the root cause of the problem.

Why Your Air Conditioner Is Not Turning On

Here are the most common reasons why your AC unit won’t turn on:

Tripped Circuit Breaker

A circuit breaker can trip due to several reasons including an electricity overload. Regardless of the cause, if the circuit-breaker providing power to your air conditioner trips, your AC won't turn on.

Blown Fuse

Your AC will not turn on due to a blown out fuse. A multimeter test can confirm whether the fuse is working correctly or not.

Icy Build Up

Your AC would absorb moisture from your home under normal circumstances. However, dirty air filters will cause the water droplets to freeze and eventually form an icy layer on the coils.

Dirty Evaporator Coils

When debris accumulates on various components of your AC, including evaporator coils, condenser, it makes your system less efficient. This can ultimately lead to a total AC breakdown.

Refrigerant Leak

If you have a refrigerant or freon leak, your AC won’t start or function as expected. It can also lead to refrigerant poisoning.

Faulty Motor

A faulty motor is another significant reason for your AC not turning on. When your AC produces strange noises before it stops working entirely, the problem can be a faulty motor.

Faulty Wiring

The wires in your unit or the one that connects your unit to an outlet can get eroded or damaged. These faulty wires can be a significant reason for air conditioner breakdowns.

Bad Thermostat

A thermostat can become blank, broken, outdated, need battery replacement, or develop other similar issues. Any of these thermostat issues will prevent your AC from turning on.
