If it's a 90% furnace make sure the condensate drain is clear. Check for restrictions in the vent pipe.
Where is the drain?
Is your furnace vented with metal vent or pvc pipe?
Metal, it's a mobile home, checked vent on roof, does not seem to be blocked
See wiring diagram PAGE 1 on below doc. You do not have a pressure switch in that unit you have a Centrifugal Switch built into the small combustion motor/blower. This unit is a Direct Combustion burner style.
NOTE: if this unit is on LP Gas and you do not know what you are doing I highly suggest you call a professional that does. With LP gas these babies go BANG if you try and jumper out the centrifugal switch for testing purposes.
If using Natural gas it is not quite as bad but still will go bang. Just a friendly warning. The switches do stick in these small combustion motors.
