I am having issues with my unit. . Damn goat chewed through my wires now that that's fixed when I turn my air on nothing happens. Checked my breaker and getting power to the contactor. Just not engaging on its own. When I manually depress the contactor in will turn on.. can the contactor be bad since dummy chewed and possibly shorted it out? Ty

I'd look in to another line being disconnected or not properly connected. If the unit works manually closing the contactor, it could be bad but I lean more toward the contactor coil not getting a signal from the thermostat.

Do you have voltage on the low voltage wires to the contacter?
Check for blown fuse in inside control unit.

I have power to the unit. Could it be the capacitor? When it turns on it don't blow air inside like its not getting relay to the thermostat

It ended up being a little breaker switch in my furnace in the control panel. . A repair man would have gladly raped me I'm sure. . Ty guys
