    Just need a residio or white rodgers combo fan/limit control with the appropriate probe length.

    Measure the insertion piece. Resideo Fan/Limit. It comes with instructions when there's two different voltages, which you have. You'll have to cut a jumper.

    Probably will have to drill some new holes to mount it, don't go too deep and use short screws, you just want to drill through the cabinet, not in to the heat exchanger.

    Honeywell L4064B. They make several models. Insertion can be 5 1/2", 8" or 11" Fan/limit control
