Old Thermostat

I have an Old Thermostat White-Rodgers 1F80-40
It suddenly stopped working.
I replaced batteries - no display - nothing happens.
Any ideas if there is another aspect which would cause it to just stop working very suddenly!

Welcome to the forums.

As far as I can tell..... that thermostat is strictly battery powered.
That means the display should be active even if the equipment was shut off.

Check and make sure the battery contacts are clean.
Confirm your batteries are good.
