Have a Evcon model #GCGD36S21S2A Puppy chewed wired and now compressor won't kick on nor will thermostat turn on. Three wire system but looks like only white wire was hooked up. Nothing when rubbing white...
There will be 2 wires hooked up in order for the system to operate, the color of the wires are not really stanard, allot of installers will use colors of their choice, it usually is yellow and blue, but the only way to know for sure is to remove the thermostat from the wall and see what colors are hooked to the "Y" and "C:" terminals... then make sure that those two colors are connected to the 2 wires that are out in the outdoor unit - air conditioner, at the outdoor unit, it does not matter which color goes to the wires.
example: lets say the outdoor unit has 2 yellow wires, and lets say that the 2 wire that are connected to the "Y" and "C" terminals at the thermostat are yellow and blue, just hook the blue wire to one of the yellow wires that come out of the outdoor section of the air conditioner, then hook the yellow fron the thermostat to the other wire coming out of the air conditioner. All it is doing is energizing a coil in the contactor in the outdoor unit, like a light switch that gives power to the compressor. Now........
If the 2 wires coming from the thermostat were touched together, that would creat a direct short in the 24 volt circuit in the furnace - inside of the house, hopefully the model of furnace or air handle will have a spade type automotive fuse located on the computer board in the furnace, if so this would save the board from shorting out, so look on the board, find the fuse and see if it is blown, if so replace it with a automotive spade fuse of the same type, usually 3 or 5 amp. If there is no fuse it is a good chance that the 24 volt transformer of the board itself is shot - this will require a AC tech.
NOTE: Turn of power to the furnace and the A/C outside, before looking at anything. The thermostat wire to the out door unit is a 24 volt line, this is usually a pencil or smaller sized wire, "Brown" or sometimes "White".
I wish you the best, and hope it helps, I am new to this site, so I am still getting use to it.
