My dog ripped the 2 control wires out of my outdoor a/c unit. i have no idea which wires are needed to make the compressor and fan work again. i understand that every installer may do things differently just looking for some direction on determining what wires may be used. or how to test which wires run the outdoor unit i do have a multi meter .

There are only two wires, it doesn't matter which are connected for a straight cool a/c.

Really, you need to replace the low voltage cable from the point where the exterior insulation got damaged. Would have to splice it properly and use heat shrink on the exterior, or do a splice inside the house, putting a new cable outside.

18/2 wire is required. There are many ways to splice, for your I would recommend crimp style connectors.

In the states try a place like radio-shack for the connectors.

im not worried about the wire repair i have done plenty of that my concern is hooking up the correct wires. there obviously has to be wrong and right wires. whoever originally ran the wires ran 18/6 outside as well so i dont know what wires were used for the cooler.

Trace the 18/6 back to the airhandler and see what they used at the circuit board.

OR you could strip all the 6 wires and carefully hang them in the air. Then turn on the AC. Then put your meter across each wire until you find the two that have 24 volts. Hookup the AC to those. Does not matter which of those 2 you connect at the AC as the contactor is not polarity sensitive. Be careful the wires do not touch or you could blow a fuse on the circuit board or damage the transformer. Get a helper to hold them. Not high voltage ( 24 volts ) and unless standing in wet grass it safe. Wear gloves if you want to be safer.

On your T/S the "Y" terminal with the yellow T/S wire needs to go to your contactor outside- (note yellow may change color @ AH) Then you will need a "C" common 24 volts ac to go to other side of contactor. To find a "C" common 24 volt ac wire -you may need to look inside of your AH

T/S on cool/auto/temp#s low--- ck wires outside until you find 24 volts ac - I would try first yellow & blue --lots of tech's use blue as common 24 vac-- If cannot find voltage, may have pop fuse- check for 3 or 5 amp fuse @ control board inside AH and or inline fuse--- on transformer high volts coming in /24 vac coming out--If no 24vac coming out TR might be burnt out?? Do you need help finding a "C" 24vac wire???? Look @ TR might be written on TR????

I appreciate the help. Sunday I'll check for voltage at the ac unit if nothing works I'll head up into the attic and check out the air handler check fuses and get pictures of wiring. Will post an update

Looks kinda frustrated now with having to wear the cone.

My Sister's lab/Husky cross chewed the foam insulation off the freon lines on the AC when a pup. They follow their nose and if it smells interesting then "chew". At least for the first year.

Glad U got it going. That was a simple procedure.:smile: You should see the fun you have when you get 2-3 chunks of tstat wire cobbled together and they start mixing and matching colors and you have to trace it with a ohmeter and jumpers.:vs_mad:
