York furnace 3 red lights and cutting out

[tinto99]

Hello, pressure switch seems to open while inducer is running. Heat shuts off. I get 3 red blinks. All hoses look clean. I feel air venting outside. Water condensate seems good. Any ideas?

Anybody know what might be wrong? Inducer comes on, pressure switch closes, furnace ignites. Then the pressure switch opens after a few minutes operation stopping heating but inducer still running. Is the switch glitchy?

u need to put a manometer in the line to see what the actual pressure is, then compare to the switch rating. without a pressure number at the point it cuts out, you are just guessing.

Update, swapped pressure switch, still fails.

Looks like I have an inducer problem. I removed the motor assy, and the spin seems to be eccentric so the impeller hits the housing and even punctured it, as well as visible damage to blades.

Can you please let me know what the part number / source for this part is? Thanks.
