I have at least a 10 year old Goodman gas Furnance. The past couple of days the burner and blower did not come on. I do not see any indicator lights come on. The inducer comes on, but nothing else. I took the air pressure switch out and blew air into it and the air hose. I reinstalled the switch and everything worked fine. I've done this twice in two or three days.
My question is - does this seem like a faulty air pressure switch or is it an indication of a bigger problem? I can easily buy and swap out the switch which would tell me the answer, but before spending $25 on the switch - I thought I'd ask here.
