I removed my Suburban furnace to check the sail switch, then reinstalled it. Now it won't respond at all to the thermostat settings... totally non responsive. Also the air conditioner as well. What am I missing?
Welcome to RVF, @Bob h; glad to have you join us here. Sounds like either something in the thermostat circuit was not reconnected properly, or the thermostat is either turned off or has failed.
Double check what you have done before things quit working. Also, check to see that you are getting 12V at the t'stat. Is this a three wire stat or a five wire?
