The 6 Most Common Reasons Why Your AC Won’t Turn On

In the summer, your air conditioner is of the utmost importance. Without it, you wouldn’t be able to escape the stifling heat and humidity. That’s why when your air conditioner breaks down, it pays to know what to do to fix it. In this post, trusted local plumbing services and HVAC provider A-1 Comfort Care Heating, Cooling & Plumbing shares some common reasons why your air conditioner won’t turn on and possible solutions. 

Power problems. Although this might sound self-explanatory, you may sometimes forget to check the most common cause for your air conditioner not turning on – power issues. First check the breaker box for any tripped breakers. If there are any, flip the breaker off before flipping it back on again.

Faulty control board. Most air conditioners these days have something called a control board or PCB assembly. This effectively controls all the different small elements of your air conditioning unit. Because of this function, it can be extra tricky to figure out where the issue lies.

Temperature control issues. The temperature of your air conditioner is usually controlled by a sensor that scans the room to monitor the temperature. If this connection from the sensor to the electrical unit is faulty, the temperature will never cool down. 

Clogged AC drain line. Lack of maintenance will cause the AC to eventually become overloaded with moisture and clogged with gunk. Be sure to keep your condensate drain line clean by pouring a cup of boiling water down your drainpipe every month. Consider hiring a plumbing service provider to make sure you eliminate the clog.

Thermostat is defective. The thermostat is your way of communicating with your air conditioner. So, if the thermostat isn’t working properly, there’s no way for your AC to know that it should be switched on. If your thermostat is off or your thermostat is showing a blank display, try to switch it on. If the thermostat doesn’t turn on, it could also be a case of dead batteries. 

Air filter is clogged. An old or clogged filter can cause your air conditioner to turn off or perhaps even freeze up. Before checking to see if this is the issue, set your air conditioner to ‘OFF’. Turn off the breakers that supply it with power and replace the air filter. Once you’ve changed it, you’ll have to wait a while for the ice to defrost. Don’t turn on the air conditioner before this happens, because you could damage the unit.
