Can you trace it back to breaker box? I'm thinking green and yellow are not needed but only way to tell for sure is breaker box. Volt Ohm meter would be helpful also.

How to connect a thermostat to a bryant 80+ furance.


First thing is to turn off the switch on the side of the furnace, next remove the old thermostat and the wires from it. On the new thermostat you should have y, c,w,g,r therminals. The yellow wire goes to the Y terminal, the white wire goes to the W terminal, the red wire goes to the R terminal, the green wire goes to the G terminal and the C is comonly not used.

I replace the blower motor with a MARS 10585 4 wire and my unit only has 3 wires. I think I have wired wrong because it runs for 15 minutes and cuts off but the outside unit still runs. The motor I...


Sounds like the old motor only had 1 speed. You will only need to connect one of the speed wires, probably the Hi-Black. Tape up or put wire nuts on the other 2 speeds. Connect the Hi to the red you have and the yellow to the white. The green should be a ground wire. Look at the label on the motor to verify what I have said. Let me know if it doesn't look like it matches this.

Replaced fan motor for outdoor ac unit old fan has blue,black,red,and green wires new fan has brown,black,yellow,brown/white and green what goes where


Hi, the 2 - brown wires are for there own run capacitor they should have sold you. One of the browns will have a white stripe. The new cap has only 2- terminals and you put a brown on each side. The black and yellow wires are both hot which 1- will go to 120 volts on the load or out side of the contactor, and the same with yellow, 120 volts. This gives you 220 volts to run the motor. Look on the new motor and you will have a diagram or on a paper that comes in the box. The old motor used the dual cap to run the compressor to. The green is just a ground wire. Screw it to any metal part or screw. You should be able to put the black and yellow hot wires where the old black, red, or blue were as long as they are 120 volts which I am sure they are. Get a cheap tester when you go get the cap for the new motor, and check the old blk, red, and blue terminals to ground and you should have 120 volts on at least 2 of them. Put the new yellow to 1 and black to another, browns to the new cap and your off and running. Keep me posted. I do this everyday. Please be kind when rating me, thank you.

R-Red is power
Y-Yellow is cool
B-Blue is cool as well
G-Green is fan leg
W-White is usually heat Leg


If you have no indoor unit and this is a ac/gas or
electric outdoor unit try this.

R to R/Red to Red
G-G/Green to Green
Y-Y/Yellow to Yellow
W-W/White to White
-Dont Hook up Blue.

Turn power back on turn the fan to on,fan should run
Turn to Heating, heating should come on
Turn on Cooling,if cooling does not come on switch yellow with blue.

Low voltage wires


I just tested a mastercool control box and found these 4 control wire colors:

Red (24v supply)
White (pump)
Green (low blower)
Yellow (high blower)

The yellow acted as a common for testing when the blower was not on high.

Blower on low just green has 24v.
Blower on high green and yellow have 24v.

If there was a fifth wire added hopefully it would be a ground wire.

There was also the low gauge wires that were black, white, and ground that were not control wires and delivered power to the control box.

Motor Wiring
Old Motor
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
New Motor
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.
