I'm not going to spend another $24 by that time it's 60 bucks I could have had a serviceman out tell me what's wrong with it just give me a couple things you look for what would send that error pressure switch

The phone call is a computer generated offer.

I am not set up for phone contact.

Pressures switch -

blocked chimney or vent pipe

Tube to switch cracked or blocked

fitting on furnace that tube attaches to must be poked clear with paper clip sized wire.

Try those and get back to me as we continue until your good.
