The furnace runs fine most days but lately in the middle of the night and it only happens at this time you hear it kick on then goes off right away does this a couple of times. Then it runs but not heating to room temp. Example last night had set to 74 woke up to it running and it was 65 in here. It seems sometimes if I kick down temp to past room temp and let it kick off leave it for a few then turn it back up it will heat to set temp
