The fan works on...

The fan works on my White Rogers thermostat, but the screen is blank. I have changed the batteries, but wince the fan works, I doubt that is the problem.

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.

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

I'm not sure I'm able. What happened is the thermostat was stuck at 68 which is the usual setting I keep. When I tried to raise the temperature, it would not respond. There was a "battery" sign on the thermostat. I then changed the batteries, but then the screen went blank.

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

Well, there was a black emblem on the lower right corner, but since I saw the battery sign, I did not look at the emblem closely.

How can that be the problem since the thermostat turns down the fan.

Just to make sure there is good contact of batteries

1 don't know. I am checking terminals now.
Customer reply replied 3 months ago
That did not help

while you have t-stat appart, check if there is a wire on the C terminal.( 24v Com ) from furnace. if no C terminal or no wire on C term. means its battery powered only

There is a wire on both ends of the battery termnals

Not battery terminals, t-stat wiring terminals, like R, W, G, Y , C,

check if there is a wire on the C terminal.( 24v Com ) from furnace. if no C terminal or no wire on C term. means its battery powered only

I thought this might be a simple fix, but I'm not sure that I can do this. I'm an 81yearold widow lady who likes to try to do things herself.

I see

T-stat will probably need to be replaced.
