Customer Question
My Honeywell thermostat is...

My Honeywell thermostat is blank on the screen. Furnace is not working. Tried the fuse to the furnace and nothing happened.

Contractor's Assistant: Just to clarify, do you think this is a larger HVAC problem, or something specific to the thermostat?

I don't know. Had trouble with the thermostat a few weeks ago and a tech walked me through setting it up and it has worked great until tonight. Came home about 15 min ago and the house is cool and the Honeywell thermostat is blank on the screen.

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

If you walk me through it

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

No, I don't think so

There are no batteries in my thermostat. Is that possible? I remember the tect saying it operates on wi-fi. Is that true?
HVAC Technician: airheatman, HVAC Technician replied 7 months ago

You should be getting power from your furnace.The issue could be as simple as a float switch in your drain that could be blocked. Look and see if there is a float and if so lift it up to see if we get power to thermostat.

Let's continue like we were. I really can't afford any added expenses right now. The furnace cost $196 last week to clean two components. $70 just to walk in the door
