I have a York unit. The A/C has worked fine all year. I went to turn on the heat this morning and nothing happened. The tstat clicks on and the exhaust on the unit runs but the heat and the fan doesn't come on. I can switch back to A/C and it comes on fine. I had my unit serviced in the spring.

yes, base on what you told, nothing we can say. Go to furnace room, remove the upper lid, watch and hear what's going on and tell us. thank you.

I like fixing everything.

Bad pressure switch, open limit, bad ignitor, bad board...

There is a lot that could be wrong with it. You're going to have to suck it up and call for a tech to come out.
