    Hi folks. I'm looking for a little advice. I have a friend who's froling ran away last week doing some expected damage.She called me because I'm often the guy who gets called for boiler issues heating issues etc. I should say I've never worked on one of these but the problems seemed obvious enough to me. We found cooked control wires of course. The ID fan lead, the fan speed sensor lead the boiler sensor lead high limit control. These have all be replaced for the most part however the fan speed sensor that was sent was for a newer model. The folks at tarm usa talked me through connecting the new lead to the old sensor.
    I'm getting this screen now. I'm not sure if it the sensor the ID fan motor or maybe the capacitor? My thought is it is the sensor. Do any of you folks have experience with this? I'd like to get it functioning so I can move on to the cause. Thanks for any input tips or insight you have.

    Yes they are helpful. I've been on the phone with them. Zero complaints with them or the appliance. I'm learning about the froling as I go. Really just looking for insight. Anything I should ok for.
    The only thing I wish I could find is a detailed service manual. I'm sure there is something more than the one that came with the boiler? Maybe not.

    It's 120 to the motor and at the motor. 13v at the PCB for the fan sensor. Motor spins free.

    Yes It has been resolved. Apparently there is an extremely fine line between the sensor being in proper adjustment and being out of adjustment. I still never got that shaft to sensor gap number.
