I got a question. I have an old Homart gas fired furnace model # 735-201, serial # 21373-L-56 Sears Roebuck Co. Chicago, Illinois. My motor doesn't seem to work propertly, it makes that noise, sounds like its hitting something, my landlord said he ordered new motor fan and he said he got the receipt but then he told us they don't make parts for it. So I'm like how do you get a receipt on something they don't make. I need to find out if they make parts for it or not. Thanks for any help.
