Air conditioner won't turn on - Goodman Heating & Cooling

A very common problem that can cause unit to not turn on, assuming you have checked breaker on and no other mechanical problems, is the float switch on the overflow pan. Check you overflow pan for excess water. If this is your problem, your normal drain is clogged and needs to be unclogged.

Another problem that sometimes causes the controls to turn off, is the fuse blows on the air handlers control card due to some control circuit is pulling to much power and blows the fuse. If this is the case you will need an experienced techician to find the cause of overcurrent. It could be but not limited to solenoid coils on main contactor or reversiing valve. It could be a shorted control wire or shorting thermostat wire. Hope this helps.
