AC Not Turning On? Look at These Possible Causes

Warm weather ends everyone running to turn on their air conditioners. It can be difficult to survive indoors without conditioned air. However, an air conditioner that refuses to turn on can become a major problem for you and your family. Fortunately, there is no need to panic since air conditioners not turning on is a common problem. You can get it running again if you know exactly what is wrong with the air conditioner.

1.Circuit Breaker

Circuit breakers are known to trip for several reasons. This can be because of an electricity overload as well. Your air conditioner will not turn on if the circuit breaker responsible for powering your air conditioner has tripped. The solution is to find the circuit box and turn on the breaker that is in the off position. However, before doing this make sure you unplug or switch off all electronic devices. Sudden power surge can damage your appliances and electronics in your Bay Area home. Call an electrician if the circuit breaker keeps on tripping.

  1. Fuse

Blow fuse can create problems in your air conditioner. You should conduct a multimeter test to determine whether the fuse is working as it should or not. Make sure you turn off all electrical appliances as soon as you suspect a blown fuse. Turn off the main power as well. Install a new fuse in place of the blown one. Make sure it has the same amperage rating.

  1. Ice Layer on Coils

An air conditioner absorbs humidity and moisture from the house when running normally. However, water droplets freeze when the air filters are dirty. These droplets eventually become an icy layer on the condenser coils. You should turn off the air conditioner and check all air filters. You should replace the filters if they are clogged or dirty. Don’t turn on the air conditioner before allowing the ice to melt away completely.

  1. Clogged Evaporator Coils

Your air conditioning system becomes less efficient when debris accumulates on it. This includes condenser and evaporator coils. Dirty evaporator coils can cause a total system breakdown as well. You need to ensure the air conditioner is turned off and then remove the access panel. This will expose the evaporator coil. Use compressed air or a brush to clean the coils. You can also make use of a detergent soap solution for cleaning. Use a wet cloth to wipe down the coils.

  1. Leaking Refrigerant

Your air conditioner won’t function or start if there is a freon or refrigerant leak. This can cause refrigerant poisoning as well. You should get in touch with a qualified HVAC technician in this case. They will find and repair (if possible) tiny holes in the coil. You may have to replace the entire coil if your air conditioning system is old with multiple leaks.

  1. Motor Troubles

Another significant reason for an air conditioner to not turn on is faulty motor. You know the motor is giving problems when the air conditioner stops working entirely after producing strange noises. Try replacing brushes with new owns if they are the problem. You may need to get in touch with an HVAC professional if the faulty motor has worn-out bearings.
