Question about Honeywell Programmable Thermostat Heater
The thermostat display suddenly went blank today. We haven't lost any power and we checked to make sure there wasn't a fuse blown. We can't get the heat or the fan to come on at all. We have the same unit upstairs and traded the units out. Both units will work upstairs but neither will work downstairs. If you can help that we be great as it is hot here and our Home Warranty company can't get anyone out until late tomorrow.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

I would say that you have one of two issues. Either your thermostat is bad or you do not have 24v coming from the heating unit. In this case the problem would be in the low voltage circuit of the heater. At the heater you should have 24v AC when you place an electric meter across the R terminal and the C or W terminal. If you have no vaoltage across the R to either the C or W then you have a bad transformer or a blown fuse in the furnace. If you do have voltage ther and also at the t-stat then the t-stat has gone bad, replace it.

Hi, sounds like you determined the problem is not with the thermostat. That leaves the furnace that serves downstairs. What type heating system do you have?

It actually sounds like the batteries are going dead if the 24v from the furnace are not providing the power to the thermostat.
