I have a Payne Model PY1PNB036090ABAA Hvac system (gas furnace). The thermostat stopped functioning properly (fan would not shut off) so I bought a Honeywell non-programmable thermostat
and installed it. now I have nothing, no digital display, no fan, nothing. so, I removed the new thermostat, reinstalled the old one, and again I have nothing. what did I do wrong, and how do I correct it?
JA: Did you double-check the thermostat? And what about the pilot light?
Customer: Well, I am not worried about the pilot lite as it is 80 + degrees now. neither ac nor furnace seems to work.
JA: Do you plan on doing the work yourself?
Customer: well, I would like to
JA: Anything else we should know to help you best?
Customer: that is all I know
JA: OK. Got it. I'm sending you to a secure page on JustAnswer so you can place the $5 fully-refundable deposit now. While you're filling out that form, I'll tell the HVAC Technician about your situation and then connect you two.
