Question about Nordic Track T9SI Treadmill Walking Deck
Hi. I have a Nordicktrack T9si. Teg problems started with the walking belt hesitating whilst I was running. Recently the unit went dead and was tripping my fuse board. I have replaced the main controller board and the unit now runs but has no torque at all. I have cleaned and lubricated the surface. Any ideas what next?
1) you must LUBE the deck belt and rollers bearing with wax or silicone.
2) if the problem persist, TIME to replace the old board deck belt. Since you must lube the deck about 150 miles aprox.
God bless you

Likely the cover of one of the motor brushes popped off. Unplug the machine before you pop it back in place, then try it again.
If that doesn't work, most likely it's the motor control board, or possibly the console, or finally just a loose connection behind the console.
But most likely, it's the motor brush cover. I've been seeing that alot with this model.

My EXP000 is doing the same thing. But it is doing it when it is cold also.

Unplug the unit remove the motor shroud inspect the drive belt if the rubber feel slick then my recommendation is to replace the drive belt. Adjusting the drive belt may take care of the problem if you do not need to adjust it too tight. If you choose to do the adjusting and feel you have adjusted the running belt thinking it would resolve the slipping, then back the tension down until it the running belt is slipping then adjust until the slippage is resolved.

You have a wire harness that attaches the upper board to the lower board. You may have to pull that harness thru the uprights ( Attach a fishing line so you can either pull a new harness thru or the original one ) and inspect it for snags crimps or broken wires also use a meter to a continuity check on the harness ends. Since the the command signals travel thru this harness also check all connections on the lower board. Its starting point

Tighten the rear roller bolts evenly with the unit off. The correct tension is when you firmly lift up on the right and left edges in the middle of the walking belt and get 2-3 inches gap above the walking board. If one side is looser than the other, the walking belt may wander sideways. Turn the rear roller screw on the side that it shifted to in a clockwise manner(1/2 turn at a time). Test on a low speed and adjust as needed. (you may manually recenter the walking belt with your foot if it shifted too far to one side and is rubbing on the plastic edges.) You likely have a worn motor belt that needs changing or even a pulley on the front roller that is slipping and needs replacing. They all cause slippage.
