Question About York Furnace York Diamond 80
No Heat...

I'm getting 3 flashes as an error code, which the panel tells me is the pressure switch. I changed it out but am still getting the 3 blinking lights and the furnace still not coming on. Can anyone advise me what to do next. I'm working on this unit (learning process I know) so I want to try every possible remedy before going to a technician.
