We need to replace the drive belt on our trimline T345 folding treadmill. We have the new belt but we aren't sure how to proceed.

SOURCE: MY TRIMLINE brand treadmill has power but the belt

TrimLine was part of Nautilus until they were phased out Your problem sounds like the lower board is causing the problem. Not knowing where you are located it would be hard to direct you to a servicer near you , but ultimately you will need to call and see if you are comfortable in the way they handle you over the phone. If you are game to repair this the only tool you will need is a phillips screw driver. Unplug the unit pull off motor shroud and you will see a lower electronics board get a pencil and pad make a drawing of board ( stick man drawing good enough) and make notation of where all the connection go to check it twice before disconnecting and usually their are only 4 screws holding the board. Now you may purchase this board Treadmill Doctors.com just them M# and Ser# and they should be able to help you. Good Luck!!
