The tech should use a manometer and see how much pressure the switch is seeing.
He has a fancy meter hooked up to the burner box now where the hose to the switch usually runs - I thinks hes testing the pressure.

It runs with the burner box open and the pressure swtich hoses hooked up properly.

Looking like an intake problem maybe, he thinks there might be a blockage.

Update

He left and I am right back where I started.

He wants to come back tomorrow after he talks to the manufacturer and get their advice.

Another guy came over and they both checked everything they thought might be the cause but found nothing but maybe something is in the intake pipe.

He wants to come back tomorrow and cut the intake pipe to look into it to see if its blocked.

The other guy read thru the install manual and said there is too many bends in the pipe that make the overall pipe length 10 feet too long based on the install manual and maybe that’s the problem.

They also said the inducer motor is at .5 something and the book said it should be .7
Right now they left it running with the burner box open just a crack and the hoses hooked up to the pressure switch because it runs that way with no error.

So that’s it for now.
