Same problem. Seems Pella has proven to be a mfr. I will not buy again. Not only not able to find parts, even from Pella, but Cust Svc. is bad (from the 1-1/2 yr old $300 door with dual cylinders that bang your heals when it drops to 30*F, and I was first told simply, "that is normal". I argued that million dollar homeowners don't put Pella on and simply accept that!; "it's out of warranty and there's nothing I can do with that." No thanks, Pella.
