Welcome to Just Answer, my name is ***** ***** I will do my best to help you with your issue. If my initial response doesn’t answer your question then let me know and we can

continue our conversation.

What you describe sounds like a problem with the furnace not the thermostat. You need to call a heating tech to troubleshoot this problem.
