Outdoor unit won't come on?
This is a very common problem, whether it's an air conditioner or a heat pump. And there are many things that can prevent the outdoor unit from starting, some of which can be quite serious. Unfortunately, many times a service technician is dispatched only to find a simple problem that could have been addressed, even fixed by the homeowner.
Below is a list of possible causes. Please note that this is only a partial list of common possibility's. I hope they can get you headed in the right direction!
* Faulty contactor or capacitor
* Faulty time-delay relay
* Faulty thermostat cable or burnt wires
* Unit off due to an open safety device (low pressure, low temp, high pressure, high temp...)
* Faulty control module
* Thermostat not set properly
* Emergency or shut-off switch turned off
* Blown fuse in panel box
* Circuit breaker tripped or off
* Outdoor disconnect off
* Condensate pump unplugged and/or safety switch open
* Outdoor reset button tripped
* Unit "locked-out"
* Faulty thermostat
