The yellow wire is used to run your air cond. inside the air handler at the transfomer should be a row of wires that have r, c , w, G, Y hook the yellow wire to the y terminal.

Hi, yes this is your cooling wire. Connect it to the Y terminal on the circuit board if this unit has one, or to the yellow thermostat wire coming from the stat. You will either have a board with these marks on them, R for hot, Y for yellow and cooling, W for heat which is heat, and G for fan which is green. If no board, look for all of these wires as they have to be there and they may be connected by wire nuts. Just connect the yellow to yellow and the outdoor unit will run. Very easy for you. Please be kind when rating me for my help.

Carrier 48NMX042 IFM wont stop, condenser fan motor and compressor wont run


Ok first thing is it sounds like a wiring problem. So first step is to make sure the thermostat is properly connected. Which... the main thing here is there needs to be 24v dc power coming from your control board (transformer) going to the thermostat..generally that is the red wire. All the thermostat does is connect that "red" wire (power) to one of the other wires to complete a circuit. So make sure you have 24 volts... (generally about .5amps) . if you have power than switch thermostat to fan only should energize the green wire only. then switch to ac and move temp low enough that the ac should turn on and that should energize the yellow wire. for sure one of those wires is incorrect now or the fan wouldn't be on OR THE THERMOSTAT IS NOT CONNECTING THEM AND IT IS BAD. Now about the compressor and fan.... those same wires run out to the compressor unit... ok the yellow for ac.. greeen does not go to compressor unit that is for fan only (vent).. red carries the same 24 volts... one difference here is that most carrier units only have the one transformer....so you run the red wire is the +pos 24 volt..and then a "common " wire is needed which is the Ground or neg... that wire on a carrier is brown usually but could be different depending installer. The orange wire goes to the pump reversing valve it is always energized when on ac mode...when heater is on in the winter it is heat pump and is not energized so just connect the orange and yellow together... tell me more specifics if this doesn't help and i'm sure I can help you... thanks Chuck

Low voltage wiring for thermostat and condensing unit


wiring from thermostat goes to furnace/air handler "R"=24volt primary, "G"=blower/fan, "W"=heating, "Y"=cooling/outdoor unit, "C"=common/blue wire. The "Y" and "C" from the furnace/thermostat wiring go to the outdoor unit and does not usually matter as to which one goes where unless there is a control board or timer in which case "Y" to "Y"=yellow. Common to "C"=blue or black. This will provide cooling.

How to wire condenser and air handler to the t-stat


Assuming this is a standard unit the thermostat connections you will use: Y, R, G, W and possibly C.

Run two conductor thermostat wire to the condenser. The condenser will have two wires to connect. Connect the two conductors to the condenser wires and run them in to the air handler.

At the air handler, connect the two condenser wires to: Y (yellow) and C

Run 4 or 5 conductor thermostat wire from the air handler to the thermostat. At the thermostat, connect the yellow wire to Y, the white wire to W, the green wire to g, and the red wire to r.

At the air handler, connect the thermostat wires: White to w1, yellow to Y, green to G, and red to R

*Y will now be connected to the thermostat and the condenser
*If you have 5 conductor wire to the thermostat, connect the last wire (which is probably blue) to C
At the air handler, connect the last wire (blue) to C. This will enable you to have 24 volts at the thermostat in case the thermostat actually requires 24 volts to operate it.

R=hot
G=fan
Y=cool
W=heat

I just had a new Goodman 13 seer installed on 6/5/10 and the unit wont turn off and doesnt seem to cool down the house had new duct installed also they changed out the fan but it runs all day without...


CALL AN EXPERT......THE WIRES AT THE CONDENSER ARE NOT CONNECTED PROPERLY.THE UNIT SHOULD HAVE BEEN VACUUMED/PUMP DOWN BEFORE STARTING UP .POSSIBLE LOW ON REFRIGERANT ALSO.

Hi I have a goodman it wont turn on , the only


check voltage at the contactor (coil) when the thermostat calls for cooling and see if you still get 28vac; if you do, it has to be a bad contactor coil, if not, which i suspect, you either have a short in the thermostat wire going to the contactor coil or a faulty control transformer; check for loose or broken wires

Hi Proper way on wiring furnace.


I can give you a start, For heat only, R terminal on furnace to Red wire to R or RH terminal on thermostat. W terminal to White wire to W terminal on thermostat. G terminal to Green wire to G terminal on thermostat. This will get you heat but not air conditioning.

I need wiring manual for goodman mini split.


outside unit L1 and L2 are load (input 240vac)
then you have control voltage, usually yellow and blue (24vac) this connects to some 18/2 thermostat wire which goes inside as white and red.

note: this unit may only need 24v control which is 2 wires from the inside unit and also 3 wires 2 hot 1 ground for line voltage.

STANDARD WIRING
on the inside unit you have green, white, blue and red control wires.

on your thermostat you have white, red, yellow and green

you run the wire from the outside unit to the inside unit. then run a 18/4 wire to the thermostat if wired and join the following wires.

inside unit thermostat outside unit
green------------------------green
white-------------------------white
red----------------------------red
blue-------------------------------------------------------blue
yellow--------------------yellow

Goodman GMP75... keeps blowing fuses only in A/C mode. Only when I connect yellow wire from thermostat to line going to condenser contactor (24V side).


Are you talking about the small 3 or 5 amp fuse in the furnace? If you are then the control voltage circuit to the condenser is shorted, Maybe dogs or rodents chewing it or the insulation is cut by a sharp piece of metal. Sometimes the contactor will go bad and cause the small fuse in furnace to blow. Look for the simple things first, like control wires shorted. Make sure the yellow wire from the thermostat goes to the outside unit and not to the common.

Heatpump A/C not working


First,Turn on the heat cycle (Not Emergency)and see if the outside unit come on,If not,and you don't have low voltage outside,Go to the inside unit and test the transformer,If you have low voltage from the transformer but not outside,It is the low voltage wires,If you don't have low voltage from the transformer,It's the transformer.If you have low voltage outside when in heat mode,but the unit won't come on,It's the contactor.Let me know if you need more help.


Please take time to rate this fixya
