My uncle put in a whole new a/c unit in my house but is not familiar with the wiring. He did not want to try and wire it and mess it up. Could someone please help me with detailed instructions on how to wire this unit together? The serial number is: 0506199403 and model number is: ARUF048-00A-1A and this is a Goodman unit. I need to know what wire gets connected to what.

In this picture these red,white, blue, green, and yellow wires are coming from the ceiling along with the copper piping. I know only red and white are seen but the blue, green, and yellow wires are in the brown rubber tubing that cover the wires.

This picture shows the same set of wires only these are coming out of the wall, which I believe connect to the thermostat.

This picture shows two wires coming from that box. I don't know if one is positive or negative or whatever so please explain how to figure it out if there is a difference

These pictures show a bunch of wires coming from the unit going into a small plastic box and coming out only red and black wires.

This picture shows red, white, blue, green, and brown wires coming from the top of this unit.

Someone please write back and explain to me how to connect these wires. My email is [email protected] or just post some directions please!

Usually there is a 24 volt AC transformer in the furnace with the secondary winding connected to a red wire running to the thermostat and a blue wire, common, to the gas valve, A/C relay, and fan relay. From the thermostat there will be white wire to the gas valve, yellow to the A/C, and green to the fan. The thermostat is wired to switch the power from the red to the white, yellow, and green as needed with the blue completing the circuit. Most thermostats and furnaces have the contacts labeled R, B or C, W, Y, and G for the corresponding wire colors. It may be wired to have the A/C control wires return to the furnace and its controls and then a second wire goes to the A/C unit. Internal wiring may replace the green wire if the thermostat does not give you the option of fan only or continuous fan. Digital or programmable thermostats may need the blue wire connected to them.

If you just have the red and white wires running to the thermostat, you must add at least a third wire if the thermostat is going to control the A/C. You may be able to use the old 2 wire cable to pull in a new 5 wire cable from the furnace to the thermostat. If you have access to where the wire goes in the wall, it may not be too bad. The 5 wire cable should work if you ever upgrade the thermostat.

You need 5 wires going out to the outside unit. 2 small ones connect to the Y and B terminals on the control board, and the coil of the relay. If you have blue and yellow wire, connect them accordingly. Since it is AC, does't make any difference at the relay. The 2 heavy black wires along with a bare or green ground need to run from a 2 pole, 240 volt breaker to the line terminals of the outside relay. They don't to run to the furnace. The shortest, most direct route from the breaker box to the outside condenser is best. Usually the A/C unit is an add on to a furnace, and uses its blower. If not, you also need 120 V to the blower. The black and red wires labeled high voltage may connect to the blower. You may need to post back with some more details since I am unfamiliar with the Goodman unit if this isn't enough for you to figure it out. All electrical power connections must be in a UL approved box and accessible.
