Ok, here goes! My gas furnace keeps kicking on and going off several times in one cycle, and it seems to do it at night only and does it all night! The blower comes on and then the gas lights the burners then the big blower comes on and the gas goes out! it runs several times and after about 5 times it will kick off! Then by 7 am its running fine and runs fine all day! Please help, I need some sleep!
