Furnace Thermostat Is Working Fine & Showing Temps Etc,But Not Lighting Up Any Longer.should I Just Replace It?

[FluffyFiasco]

Everything is functioning as normal but the leds for lighting the digits no longer works,tho I can see them in the daylight or if I use a flash light on them.

I would just leave a little torch near it.

Hoppy... that could get lost in translation  🤣

To Americans, a torch would likely be a bushy stick that you set light to.  The sort of thing found in zombie movies  😁

Hoppy's  right though. You only need to change it if it's becoming a pain to check it.

It might sound a silly question but there isn't a battery which needs replacing is there?

Britain and America are two nations divided by a common language.
