Help with wiring on a Trane A/C unit please
Hey guys/gals, im new here just started looking around. I need some help with my A/C unit wiring that my dogs chewed. We have a Trane XE 1000 built in 99, model TTR042C100A3. The wiring that im replacing is the bundle of 5 wires that come from the house to the outside unit itself. The wires are about 14ga yellow, red, white, green and blue. The dogs pulled the wires out of the unit before I had a chance to see where they hooked up to which is where I need help. Inside the unit I have a blue wire and a yellow wire with bell caps on them but neither are attached to anything (im assuming this is where my blue and yellow will go). Also inside I have: A 10ga Green wire bell capped with a 14ga brown wire, a 10ga red wire capped with an 8ga red wire and a 10ga black wire capped with a 10ga black wire with a blue stripe. Hopefully someone can help me out with this Thanks check the colors on the subbase and inside the air handler your close to landing most of them,but verifying the colors back at those 2 points might help.the schematic prints on the air handler and the condenser will marry up all the wires to the final connections.it is the letters on the terminals(cond/air handler and stat) you want to match up by way of the colors.if that unit is AC only not a heatpump you only need 2 wires connected.reread your post......the other 10/8 capped sized wires sound like voltage wires for the unit power.so you might just be concerned with the 2-14 with the caps and single wires.see what color is on the Y terminal within the air handle or from the stat Y is the cooling call out to the condenser.R is the hot side of the transformer both are that pair required to run the condenser..check the condenser schematic and do this with the power off at the air handler.if you spark a wire on the 24V and it isn't fuses the TR will need to be changed.i will check back good luckBeer 4U2 This almost sounds like its three phase. Read the data plate on the outdoor unit where the voltage is it should say 208/230V 1PH (for single phase and 3PH for three phase). The 10GA wires are power but you already have a black and a red and a green for ground. The black with a blue stripe concerns me.... Check that phase! I assume your not on a farm because farms do have three phase. Normally residential doesn't. It may have just been a spare wire ran and not connected at the other end either....check that....see where the wires connect inside. The blue and yellow wires in the unit are your control voltage connections. You need two control voltage wires coming from the indoor unit to attach to them. I am surprised that you don't have 2 of the five wires that are stripped while the others aren't. You need to look inside your furnace and you will find one wire of those five tied to the C terminal or the common side of the transformer and the other wire will be on either the Y terminal on the board or tied directly to the yellow wire from the stat. I looked at the air handler and only the blue and yellow are hooked up. I found a schematic and hooked those two up outside to the unit. I hit the breaker for the ac and handler on and then tried to turn on the ac but nothing happened...tried to turn on the heat....nothing happened. Since I cut power to them both do i need to reset the unit or something? are you getting any indication that you have at last 24Vs either lights on the stat or clicking anyplace.the dog might of shorted the wires when they were pulled.the 2 wires out to the condenser have nothing to do with the heating if your running a gas furnace,the only thing is the transformer within the air handler check it with a meter if possible on both sides 115/24 . You have lost control voltage, check for a fuse on the board of the indoor unit or an in line fuse coming from the transformer. Procedure is out of order. First thing to do is take a stick and knock the dogs up beside the head real hard. After that is taken care of, replace the fuse and you you should be good. Are you saying the only wires they pulled out are thwe small ones? if so, that will likely be bundled in a brown casing with other thermostat wires. nTrace it back to the air handler and find the two that are connected and follow them back to the condensing unit and connect them to the coil sides on the contactor... likely yellow and blue. Those yellow and blues will go to the contactor coil. To test it put it in cooling mode. Sorry for the confusion earlier it sounded like the dogs pulled the power wires out as well...That would have cured thier problem fast.
