Breakers are a safety device. It is designed to protect not only the equipment but the wiring and the house as well. So when it trips, there is a reason and it should be taken seriously.
One very common cause for breakers to trip are loose electrical connections and can easily be corrected by tightening them. Try one time to reset it by turning it to the “off” position and then back to the “on” position. Do not just keep resetting it and try to ignore the situation. It is trying to tell you something.
And while it may be just a weak breaker or the result of a thunderstorm, always remember that you are dealing with high voltage, high amperage and possibly high temperatures which can cause serious damage to life and property. Note that breakers should not feel hot to the touch. If it is hot, it indicates a problem and not to be ignored.
For example, if when you reset it, it immediately trips, that is usually indicative of a direct short. Do not even try to reset the breaker again.
Sometimes the breaker for the outside unit trips because the compressor is having a hard time starting and will require a “hard start” kit to get it going again or it may be as simple as replacing a defective capacitor.
Below is a list of possible causes and things to check. Items in
Low voltage to the house as in a brown-out
