I have a Goodman furnace that was installed in 2006 and was working fine until I changed out the thermastat to a programmable one, which is a Hunter model 44155C. I matched all the colors with the correct letters except the blue with I am not sure where that goes. The old thermastat was wired and had no battery and worked just fine. I can not even get the blower to turn on. Where did I go wrong? Did I blow a fuse in the furnace. I checked the breaker and it is fine and not tripped and the batteries on the thermastat are bran new lithium batteries. The themastat is only a year old too. What else can I check in the furnace that I can fix myself? I can not afford a furnace repair person to come out and fix it. We have not had heat for five days and it is getting cold. Please help! Thank you

What's the old tstat and can you wire it back up so it will work? First order of business is getting the heat back on, next is getting your new tstat mapped to the old wires. One thing at a time.

It is possible you blew a fuse or fried a transformer. Let us know what wires you have and what colors they are, and what they go to if you know.

You should be able to jumper the red and white wires together if wired rule of thumb,that will get you some heat ,if not something is wrong with furnace,, then get you a good tstat,that hunter is junk,, when you jumper the stat wires and it does work, it won`t cut off till you seporate the jumpered wires
