I have a FV4ANF002 indoor unit and a carrier tstat CCPRH01-B on board and this number 3101N026720. The display has gone blank. It has no battery. The bfan kicks on at low speed and runs 30sec. then stops. Has my stat croked or is it something else? My unit looks brand new insisde and out. 410A system. with electronic air cleaner. Screen just went blank on stat. Please help me.

You probably have a blown fuse or tripped breaker. Check for breaker and/or 3 - 5 amp mini fuse in furnace on control board. If the fuse is bad, you may have a low voltage short. Have you cut your grass around your outside unit lately? You may have cut a wire. Hope thi helps.
