Im getting error light, pressure switch stuck open.

I have a York Diamond 80. I have two units in my house, upstairs and downstairs. Im more worried about the downstairs unit.

So I went to the upstairs unit and took the pressure switch and replaced with the downstairs unit. Worked for a few hours and now getting error stuck open again. The motor is not even coming on.

Is the motor suppose to come on before I get the error code? When I hit the switch the error code comes on without the motor coming on. So what I did now is went to the upstairs unit to replace the motor as well. Still nothing. Im thinking my upstairs unit was working so I don't know what could be causing this.. Any ideas?
