Question about Coleman Propane Forced Air Heater w/Electronic Ignition (50,000-80,000 BTU)
Trying to turn on central air and three amp fuse keeps blowing when turning on to cool
BEWARE OF HIGH VOLTAGE! 220VAC CAN KILL YOU! That said, it sounds like you have a short in the control (24VAC) curcuit to the condenser. A mouse probably made a home in the control compartment of your condenser. BEWARE OF HIGH VOLTAGE! 220VAC CAN KILL YOU!

Turn tstat off. Outside at condenser carefully remove the low voltage wires (likely two) inside the small wire nuts. Cap these two wires back (unhooked from condenser) with the wire nuts. Turn cooling back on. If the fuse blows again you will know for sure it's somewhere in that wire you have a short, and as the guys said, likely rodents. If it does not, then you will likely need to replace the contactor, or, if your lucky it's in the small wire in between where you unhooked and the contactor. You definitely have a short, just gotta find it. Good Luck!!

There is probably a short in the control wires to the o.d. unit. Look at the small wire that runs with the copper lone set, at the o.d. unit. See if they are touching? Look inside of the o.d. unit. If there are any wires that may be rubbing on some copper. Also, if your copper line set, at the indoor unit, runs under the house, varmits like to chew their way in. Process of elimination. May be a burnt coil at the o.d. units contactor. Hope this helps and please work safe!
