My furnace stopped blowing warm air and I saw four blinking lights which is for a limit switch. I reset it by whacking it, and it worked for a little while again, maybe an hour or so, but then stopped again. I bought a new limit switch and replaced it, and that seem to work again, but then failed. I still have the four blinking lights. Is there something else I should check? Is there a way to reset the entire system other than turning it on and off as I've already done? Any help would be great! Thanks all, John
