Question about Heating & Cooling
SOURCE: Air Conditioner malfunction
Hi, Sounds like you have a short in the control circuit to me. Turn off all power going to the unit. Write down or otherwise mark the wires leaving the control board going to the thermostat. Remove them from the control board. Replace the fuse. Turn power back on and see if the fan still runs. If it does, check and or replace the heat limit switch that brings the fan on during the heat cycle. It may just need adjusted. If the fuse blows, I would think that the control board is probably bad. If it doesn't blow, Remove the thermostat. Leaving all thermostat wires open check them with an Ohm meter. There should be no continuity between them. Twist all the wires together at one end and ohm them again at the other end. You should have complete continuity on all wires. If the wiring checks out, down power the unit. Double check your wire colors and rewire the control board. With all wires open at the thermostat, turn the power back on. Touch the RED wire to the YELLOW wire. The Condensing unit should come on. Touch the RED wire to the GREEN wire. The fan should come on. Touch the RED wire to the WHITE wire. The heat should come on. Down power the unit. Replace the thermostat. Test unit. If the fuse has lasted ok but blows now it is either wired wrong at the Thermostat or the thermostat is bad. I hope I have helped. NOTE: If you can not understand these instructions. Call a licensed Heating / Air conditioning company. kstfas

Did you plug upper unit (on roof) into lower control unit (inside). Not to insult you, because i've done it myself, in a rush situation. Breaker on? Sure you didn't mix up any wiring?

Hook up o to o/b, then in the installation programming set the change over valve to energize in cool. Then hook up w to aux. Good luck.

567C024RCU In this model number is the # 24. That stands for 24,000 btu's. This is a two (2) ton unit. Has this two ton unit cooled ok in the past? if so replace with the same size. But make sure yo change the indoor coil to match the size "and" efficiancy of the ew unit.

I think the wiring diagram is on a printed sticker on the side of the water collector, just pull it out of the right side as you look at it. There should be one on there hope this helps as i have the same unit in the other room. regards Richard
