Do not worry about the colors, rather the terminal markings.
Usually R_Rh will get Red G will get green the may used brown on Y

I have an A.O. Smith f48l47a50 blower motor, and I need help with wiring. First it's a 460v,1phase,1/2hp,975rpm,3spd motor. My question with the wiring is do I need to supply a wire for line power? I know the brown and purple go to the capacitor. The green is ground. I guessing the blue and orange are to designate low/med speed, but that's all the wires that are attatched. I think I need to supply a wire from the blower motor relay to the motor's hi spd terminal. Could you confirm this?

Are you SURE its 460volt single phase??? that voltage is normally a 3phase motor voltage,and color of wires is right for 480/277, but that would be 3 phase.....not saying your wrong,just make sure ... Air Conditioners

The heat strip was never hooked up, there is three wires on top of the heat strip, grey, brown, and white , the thermastat is only hooked up with green yellow and red. There are two wires not hooked up a white and blue. There is a blue that is not hooked up on the unit. this is a package unit. I know that the three wires activate a relay to turn on the strip, and the white goes to both the grey and brown relays if they are some sort of relay. So I hope you can help me. drew

Thermostat wiring I have a Frigidaire Model R4GA FWA and Central A/C system. I am trying to replace the thermostat with a programable Hunter model. I do not have the original wiring diagram and the old thermostat is no help. The wiring colors I have is Green, Red, Brown, Yellow, White and Orange-(not used). The terminals on the new thermostat are RH, RC, Y/O, W/B, G, and Y1.

Your best bet and where i would start is to identify where the coulors are conected at the fernace. in the industry we use standard wireing coulors wher green is g for fan and red is rh=switched trans power for heating . rc=switched transformer pow ... Air Conditioners

I installed a new Honeywell Programable thermostat, When I turned on the AC it turned on the Heater... I followed the wiring but some of it is not making sense... G=Green, Y=Yellow, R=Red, C=Blue, W2=White, Y2=Brown... The problem is that I have an Orange and Black Wire left over, Which one do I connect to W? and do I have the wiring right... my unit is a central Heat & Air, not a heat pump.

Hi, the problem is you have bought the wrong thermostat for the unit if it is not a heat-pump. A heat pump will have W-1, W-2 for heat strips, and Y-2 is for 2nd stage cooling. G is Green for Fan, R is Red for Power, Y is Yellow for cooling, and W wo ... Goodman Air Conditioners

I was installing a new thermostat and in the process lost power to the thermostat. I crossed the red and green wires and the fan didn't turn on. I check the outside compressor and inside air handler and found no 5 amp fuse. Does it have one or did i short out the transformer in the air handler and need to replace it?
