Need help with Honeywell T87F thermostat

I have a T87F 1859 3 9324 (I assume it was built in the 24th week of 1993). The room temp indicator seems to be stuck on 72 since I know it went below that last night yet when I checked it around 3am it was still on 72 deg even though it was completely shut off. Is there any way of fixing that bottom indicator so it will work correctly? (There has been no tampering with this thermostat it has always been used properly).

Something is causing the thermometer to bind. There really isn't any way of repairing it. You could try to see why it's binding but that may not be easy.

It may be time for a replacement or just place another thermometer next to the stat.
