I have a Keeprite furnace, model C9UHX100L 20AE. I was going to start it but no reaction was heard from the furnace. I checked the LED code. It said the pressure switch open when should be closed. I did a further check. The inducer motor was not running. Could you advise me what is the possible problem?

Thank you!

Bird in vent motor? Or maybe motor is just burnt up. Remove motor and check for obstruction
