Customer Question
Our heat recently stopped...

Our heat recently stopped working and we are having a hard time getting the warranty company to send someone out before Friday. Yesterday we noticed the battery had died in our Honeywell thermostat. after replacing the batteries using the battery compartment, now nothing comes on. no heat, a/c or fan runs. is there any way to fix it?

Contractor's Assistant: Did you double-check the thermostat's settings? And what about the filters?

Everything worked beautifully before the batteries died in the thermostat checked the settings. have it set at target temp of 75* but it reads that the house temp is 58* as of this morning. filters have been changed within last month

Contractor's Assistant: Do you plan on doing the work yourself?

Depends on what needs to be done.

Contractor's Assistant: Anything else we should know to help you best?

I think that's it...we do have an infant and a cat in the house if that is of any importance

Lets make sure whether it is a thermostat or a furnace issue. Remove R and W wires at thermostat and touch the wires together .Tell me if heat comes on.

Ok one sec
HVAC Technician: airheatman, HVAC Technician replied 1 month ago

Can you look inside the burner compartment on label on side panel and get me the model on your furnace? Then look in blower compartment and see if there is an error light blinking that will guide us in determining what is failing with the furnace.)Not if no peep hole and you have to remove blower panel to see control board, it will be necessary to hold door switch in to have power to board)

We have a heat pump. Does that matter?
HVAC Technician: airheatman, HVAC Technician replied 1 month ago

Having a heat pump will make a difference in some troubleshooting steps but the heat strips should still have come on when we connected R and W

I am afraid you are going to need to get an onsite tech as soon as you can. Too many wires for me to deciper to tell you which ones to test. Was hoping it would be something simple like a fuse or something you as a lay person could fix without having the hvac background.
