My furnace blower is alway's running lately, and it won't shut off until I tap it on the side of the furnace. Than within a 1/2 hour, it's doing it again. I'm getting fed up going up and down the stair's all the time.
I am on social security total disability, and I really can't afford to call a service-man to come and fix it. Can someone out there give me some advice on how to fix it myself without calling a pro?
It's an old Sears furnace probably from the 60's or 70's.
Any help will be appreciated. Thank's, Mike
