Thermostat sometimes doesn't turn furnace on
The thermostat has been in the house over 8 years (was here when we moved in). Has worked great until a few days ago. It sporadically won't turn on the furnace. Sometimes it will but sometimes it will let the house get to 55 and still doesn't turn on the furnace. Playing with the buttons (don't know the magic formula yet) will get it to eventually work.

Sounds like thermostat is defective replace wall unit
Hello Kathy, The first thing that I would do is change the batteries in the thermostat. One or more may be weak and not turn on your furnace. I would put in Alkaline batteries. If that doesn't help, maybe a new thermostat is in order.
