Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
Please identify your treadmill a little more completely. I'm having trouble identifying its manufacturer for sure... though it may be the 'Fitline' type that was released on a limited basis 11 years or so ago, possibly explaining why parts are so hard to find... few of them were made? perhaps.
Also if you could give me the part # ***** the defective board, that would help me (or anyone else) locate that specific part.
There are admittedly few supplies for a 'Fitline' offered anywhere I can find.
But you might get something if you contacted these treadmill parts suppliers:
Phone:(###) ###-####br />Fax:(###) ###-####/p>
I'm very sorry to say, there are absolutely no hits on that board's part number. I tried finding any trace of it any number of ways, but ultimately calling parts providers and asking if any of them have it (starting with the one I recommended) may be the only recourse (aside from posting on craigslist.com's WANTED section, asking for either this board for this Fitline t400 machine, or asking for a 'junked' or to-be-discarded machine of that model that a working circuit board might be gotten from.)
(If this answers your question fully and completes the case, please rate my answer. Thanks, ***** ***** luck.)
