A functional air conditioning unit is an integral part of most households, especially during summertime. When your AC unit stops operating at your workplace, your staff members and your customers will suffer due to the heat waves. This may hinder the effective operations of your business. Therefore, you need to diagnose the issue quickly so as to ascertain the next course of action. The following are the reasons why your air conditioner won't turn on.

Your AC Machine Air Filter Is Filled With Dirt

The air filter's primary role is to shield dust and debris from getting into the system's internal compartment. For that reason, air filters require frequent replacements since dirt and debris accumulate on them over time. A blocked filter restricts airflow causing the AC coils to freeze. As a result, the unit has to use a lot of energy to cool your home or business premises. When changing the filter, turn off the breakers that supply the AC with power, and then install the new component. But after replacing it, do not turn on the system until all the ice defrosts.

Your AC Machine's Thermostat Is Defective

A faulty thermostat will not display anything on the screen since it cannot detect temperature variations. If you have a thermostat that operates on batteries, you should routinely replace the cells. On the other hand, a dysfunctional electricity-powered thermostat could signify dirt accumulation inside the thermostat cover. In this case, cleaning the cover could remedy the situation. Additionally, wiring problems within the thermostat can cause its malfunction. If you experience this, you need to hire a professional AC repair technician to examine the issue extensively and replace the thermostat if need be.

Your AC Machine Capacitor Is Faulty

The AC's capacitor is susceptible to excessive heat and power fluctuations. If your AC starts making weird noises and then suddenly stops functioning, the motor might have failed. This situation can arise when the capacitor overheats. In this case, your AC repair technician will carry out a capacitor test using a multimeter. If the capacitor is not relaying any resistance on the multimeter, then the capacitor is dying. A defective capacitor might necessitate an immediate replacement since it poses the risk of an electric shock.

As seen, the AC can fail to turn on for varied reasons. When you detect this problem, it's best to call an AC repair technician right away. They will diagnose the issue and offer a suitable remedy to avoid dreadful failures in the summer.
