Slant-fin CHS 110 boiler wiring harness repair

My Slant-fin CHS 110 boiler starting vibrating and making a horrible noise. As it was no surprise the combustion fan was shaking violently because parts of the impeller broke off. This shaking caused the speed sensor wiring to break at the connector. Of course I can't get one from the company because they went belly-up and I haven't found a parts supper listing one. The repair guy took one from a boiler back at the shop to get the new fan going. The harness was off a different model and just the motor end was correct. I spliced the two harnesses together to get one usable one. What I need is: A) to find a correct new harness, and B)find the proper female connectors so I can make a new one piece harness for both. C) An impeller wheel to replace the broken one and D) the rubber shock mount bushings that got beat to hell from all the vibrating. Please point me in the right direction on all or any of these.

    There is a recall notice for your unit - for a rubber grommet repair. Have you done this already? Basically straps the grommet in place so it can't get dislodged.


    NTI should have taken over Slant-Fin for this recall as they sold it to them. Have your tech call them up for the kit.

    Also confirms the above comment that they were both the same units.
