Question about Goodman Heating & Cooling

Open Question

I installed a new honeywell rthl111 series in Oct. 2012. I wired the blue wire to the RC because that was how the old thermostat was wired. The heat worked all winter but when I tried to change over to cool nothing would work. I checked the schematics online and realized I should have installed the blue wire to the B. I checked the fuse in the power panel and saw I had blown it. I changed it and rewired the thermostat the correct way. I tried again and still neither the cool or heat will work. Any suggestions?

Typically if you have a yellow wire in the "y" terminal blue is used as common or "c". As far as your jumper from rc to rh, that will depend upon what type of heat you have. If all of your heat and cooling come from your packaged unit outside, yes you will need the jumper. If this does not work maybe you have a bad breaker or transfomer.

SOURCE: Need help with wiring thermostat

first do you have a heat pump unit or standard a/c? standard a/c connections at the thermostat go like this red wire to rh-rc which is the 24v power and you don't have to remove the jumper.white goes to w which is the heating wire yellow goes to y which is the cooling wire green goes to g which is the fan wire and blue goes to c which is the common wire. so if your stat has rc- rh ywgc you should be set if the wires on the furnace correspond with the same alpha designation.orange may be used if u have a heat pump unit otherwise it may just be a spare you cap off and leave behind the subplate.

739dfb58-7a38-4a51-a7ed-ab942a7253a0.pngRH is red heat and RC is red cool, red being the "hot leg" of the 24 volt control voltage, normally you will have a jumper from RH to RC, the fact there is an RC tells me there must be an RH too?
I will look after this post and come back if any new info was found, other wise I will say call 1800 Honeywell and provide you a diagram to check out.

I bought new Honeywell non programmable,letters are different.


If you have a 5 wire thermostat then you have a two transformer system a cooling transformer and a heating transformer.
The cooling transformer wires to Rc - Y - G,
and the heating transformer wires to R - W the R terminal heating would be the #4 terminal from the old stat.

Yes, I believe that you will be fine. If the original wiring is correct then I have listed the basic wiring below. As always read the directions and make sure the wiring matches your system.

Red wire = Rh (24v power, should have an exsisting jumper to RC)
White wire = W (heat mode)
Yellow (or sometimes blue) wire = Y (A/C)
Green wire = G (Indoor Fan)

Jumper RH to RC and Y to W (Just like the old thermostat) and hook the cable wires as you have indicated with the exception of the blue wire - clip it back - it is not needed. This is a heat pump system so heating and cooling are done by the same unit. RH stands for Red Heat, RC for Red Cool, the W and Y are the neutral sides to the heat and cool control circuit. That should get you going good enough to start learning the intricacies of programming the box.

Normally, you should have 5 color wires: W-White, Y-Yellow, G-Green, R-Red and C-Blue.

The Blue wire is a common from the transformer on older systems, which is probably hooked to RC terminal.

Try this: Remove the blue wire and jump the RC to RH with the red wire and you will be fine. Blue wire should not be needed with the new thermostat.

This should also be stated in the instruction manual.
Hope this helps.
