Lennox Air Conditioner won't turn on. How to troubleshoot?

Today, an air conditioner has become such a common device that many people perceive it as ordinary appliances like a TV, refrigerator, washer, etc. But in reality the attitude to maintenance is different. It is rather simple to clean a washer or an oven when they get dirty. Most owners do not violate the rules of proper maintenance about the air conditioner. Unlike the rest of devices, the conditioner - is a complex appliance which demands special treatment, service and regular diagnostics. Of course, equipment that does not break has not yet been invented. And at some point, each of us may face the fact that the air conditioner will not turn on or will be bad, not functioning properly, or even without signs of life. If your AC unit won't turn on, the first thing you should check is if there was a blown fuse or a tripped breaker. There's a good chance that the problem is a tripped breaker if the circuit was overloaded. You can look for this problem in two places. First, this is a fuse box. If it’s a fuse box, look for a blown fuse. On a circuit breaker, look for a tripped circuit and flip it to “off” and then back to “on”. Then, some models of air conditioners have a fuse at the previously mentioned safety shutoff box. Try replacing this fuse, even if the fuse does not appear to have blown. If the air filter is clogged, air cannot flow properly through the air conditioner. If the coils are significantly dirty, the air conditioner will not be able to maintain the proper temperature, and the compressor will run continuously in an attempt to cool the room. As you see, your Lennox air conditioner requires professional service at least twice a year to function efficiently.
