Gas (Propane) Furnace Ruud UGRA 06emaes
I've replaced the inducer blower as the squirrel cage cracked on the old one. New pressure switch.
Not enough negative pressure to close the switch.
Furnace works when I jump the switch.
Furnace has been cleaned.

I believe the problem to be lack of a baffle/restriction on the outlet on the heat exchanger. Without the baffle there isn't enough negative pressure to close the switch. What looked like scale must have been what was left of the baffle I cleaned off. What I need is a picture of the outlet on the heat exchanger to see if indeed there is a baffle and if so how much restriction.

Tubing is new.
Heat exchanger is in good shape.
Flue is clean, Horizontal run and no restriction.
New Inducer was installed with new gasket.
No as to the silicon it is not used in this application.
I appreciate the help but am looking for specific info on the
outlet on the secondary heat exchanger.

Thanks
