9 Most Common Reasons Why Your Air Conditioner Won’t Turn On

It can be pretty unpleasant and frustrating if your air conditioner does not turn on, especially as summer approaches and the temperatures that occur throughout the summer days increase. You’ll want to know what caused the damage and who can provide AC repair services near you.

Common Reasons Why Your AC Might Not Turn On

Broken Thermostat

For specific thermostat models, batteries are necessary. It is essential to replace the batteries at regular intervals if you possess one of them. Other causes of a broken thermostat display include the presence of dirt on the thermostat cover or other electrical issues.

Unplugged Condenser Unit

The failure of your air conditioner to turn on could be due to something as simple as the unit not being plugged in. It would help if you observed a small cord running from your air conditioner to the exterior panel. Replugging the cord into the air conditioner will restore its functionality in these situations.

AC's Capacitor is Broken

The capacitor is crucial to the operation of your HVAC system. It is connected to the motor’s circuit and provides a kickstart so that the motor may begin functioning. The capacitor is removed from the circuit after the motor reaches the predetermined speed.

Contaminated Evaporator Coils

The evaporator coils, condenser, and air conditioner’s filter may become clogged with dander, grime, dust, and other undesirable particles. Debris that collects on various components of your air conditioning system not only reduces the system’s efficiency but also has the potential to cause total failure.

Clogged Filter

Your air filter may be becoming dirty because you are not replacing or cleaning it according to the manufacturer’s instructions. The airflow of your heating, ventilation, and air conditioning system will decrease over time as the filters become clogged with dust and oil.

Expended Fuse

The fuse box is located on the exterior of your home, near where the condenser unit is situated. After finding the fuse box and turning off the power supply, remove the fuses from the crate and test for continuity using a multimeter.

Degraded Motor

Your air conditioner’s motor is probably faulty if it began making odd noises before entirely stopping to operate. Performing a test on the capacitor of your motor may enable you to evaluate whether or not it has any remaining useful life. AC contractors in Lynnwood, WA, can help replace your motor.

Clogged Drain Line

A lack of maintenance makes the air conditioner progressively clogged with dust and saturated with moisture. If the air conditioner drain line does not clear with hot water, you can Google AC repair services to find the right company to have it repaired effectively.

Refrigerant Leak

If your system’s refrigerant levels are low, the air conditioner may not turn on as it regularly does. It is a regular occurrence if the refrigerant is not charged correctly after installation or if there is a leak.


AC systems require maintenance or repair at some point. It is therefore essential to hire a trustworthy AC contractor.
