Question about Heating & Cooling
I,m trying to fit a universal pcb to an a/c split unit but cant figure out which wires to use for the speed settings on the internals fan.there are 6 wires Black=n, white & red to relay red =L, Grey,yellow and brown.
If I connect the red to any of the speed relays on the pcb it works but only on that speed. There is no pcb terminal for the Red L only for the speeds.
any help would be appreciated.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

SOURCE: Wiring compressor
The two terminal cap is only for the new fan motor. Connect the compressor wire back where you found it, on the 3 terminal cap. It's the terminal marked, "herm". The "common" terminal on the 3 terminal cap must still be connected to one side of the 220 power at the contactor. One side of the 220 goes to the common on the compressor. The other side of the 220 goes to the run winding on the compressor AND the common terminal on the 3 terminal capacitor.

You almost have it Look closer at the run capacitor. It has Herm, this is for the compressor, Com or C and F or Fan.
1 of your power wires is the fan speed so connect them accordingly usually black is hi, blue med, & red is low. You are "feeding" voltage to the selector switch on 1 side and coming out to the fan motor speeds.
Next you have a "Common" wire on your fan motor (this means its Common to all the other connections inside the fan motor to me. It is usually white. Connect this to the other line of power usually the Com on the capacitor unless it connects to a strip on the selector switch. But 1 of these 2 places will be the other side of your Power when plugged in. Lastly the brown it is usually the fan capicator only wire and it will connect to the fan "F" terminal on the capicator this terminal will not have any other wires connected to it.
This should make you a happy camper. Please rate me accordingly and good luck.

SOURCE: I am replacing the a/c
Brown wire is Start
Yellow wire is run or Power
Black wire is High Speed or Common
The other two taps are speed taps, but you have a single speed application
And high speed is what you need ,that’s why there’s not any wires
on Red and Blue if high speed was to much then you would move the
Black wire to one of the other taps RED low speed or Blue Medinm speed
White goes to the Yellow wire from the capacitor
Black goes to the Black wire you took off of high speed on old motor
Of course both Brown wires go to the capacitor and Green to ground
If a capacitor doesn’t discharge it doesn’t mean it’s bad
but the capacitors don’t last as long as they used.
Any time you put in a new motor always replace the capacitor
It will save you a lot of time and grief later on.

There should be a wiring diagram on the side of the new motor.
The brown and the brown w/ white go to the new capacitor you should have bought with the motor.
The black and white go to your L1 & L2 power source. The remaining wires must be capped off.

Testimonial: "Thanks for the info. although a day late it confirmed what a friend had told me also. Didn't see any wiring diagram on the new motor."
