Problem: Goodman GMNT to Hunter 44155C Thermostat
 
1 Attachment(s)
First time poster here hoping someone can shed some light on my problem...

I have a Goodman GMNT Furnace (Manual)
I just purchased a Hunter Programmable Thermostat 44155C which looks something like this:

My problem is I cannot seem to get the wiring set up correctly. Ignore the wiring in the picture, that is not my photo.

I have a 5 wire thermostat wire coming from my furnace. G, W, Y, B, R

My AC Unit outside has a red and white wire running from it to the furnace. They are tied into the thermostat lines.

Please view my attached schematic for more detail.

I have tried a great many wiring combo's but none seem to work well. The best I can get is the AC and Furnace to turn on at the same time.

Any help would be GREATLY appreciated!

Wire nut one of the wires from the a/c unit to the blue wire. Then you should follow the r to red, green to g, white to w/b, yellow & the other a/c line to y1. Not being there, I am making an educated guess that the blue is the common connection at the control board. It wouldn't hurt to verify this. Good luck

If this is like the stat you have it is for a heat pump but will work for you so..

Red to RC/RH
Green to G
White to W
Yellow to Y1
and tape off the blue

I thought shipuppride wrote the condensing unit wires are going to the stat, thats why he needs the blue. But after further review..whoops. I stand corrected.

Hi,

I am having this same problem with a Hunter 44260. After reading the posts I checked my wiring and it is wired as suggested. I have included a photo for clarification. Are there any other options?

Thanks for responding.
