I have a heil furnance model # 867.768242 when i turn it on it lites up normaly. then after about five minuts the burner turns off, and relites itself 20 seconds later. this action will go on repeatly over & over for twenty mins or so. then finally the burner will stop liteing all together. please advise i am freezing!.
look at the circut board,,,is it blinking a code,,,if not it might be the flame senser needs cleaning,,,might be anticipater in tstat need reset,,,let us know
