I have Pacemaster SX-Pro with electric incline that has quite working. It has been used very little considering its age. I have some electrical knowledge and have performed some checks. I have confirmed power up to the lower circuit board. There does not appear to be any power beyond that point - nothing illuminates at the upper controls/circuit board. Can your company test both upper and lower circuit boards and determine as well as repair the problem? I can send both circuit boards as I have them disconnected at present. My plans are to sell the treadmill after it is repaired unless it cost of repairs make it not feasible. I would like a cost estimate before repair(s) are made.
