Customer Question

I have a several year old NordicTracak T5.7 (model # *****). Recently, it has started making a squeaking/groaning noise when it is used with an incline. I can't be 100% sure, but it does not appear to me to be the belt itself (or the belt against the surface of the treadmill), I used to have an older one that did that... that noise was a lot more high pitched and whiny. This happens when the treadmill is fixed at a given incline and as you take each step and put your weight on it there is a fairly loud squeaking/groaning similar to the stairs of an old house creaking as you go up them, but louder and more metallic. I'm not sure if something in the incline mechanism needs to be greased, is broken, or there is something else that is triggered when it is at an incline. When the treadmill is at 0 incline, it is perfectly silent.

This could be several things. I understand you have ruled out the belt. What I would suggest doing is opening the machine and testing both the main motor and the incline motor. To do that, apply 12-18 v DC directly to the terminals. Then you can find out if the motors themselves are causing the sound.

I would also check the belt for wear though. When on an incline the can be more friction between the belt and the deck and if the belt is worn, it can make all kinds of sounds. If neither of those help, let me know and we can go from there.

The other thing I have done to confirm it isn't the belt is to simply have the treadmill go to an incline, let it stop at that incline, completely turn off all power, and stand on the belt and just flex my legs quickly without taking my feet off the ground in order to mimic more/less of my weight being supported by the treadmill. Just that action still causes the exact same noise, the belt is completely stationary and none of the motors are running.

Ok, so just the pressure on it when on an incline with nothing running causes the same sound?

Expert:  Michael Hannigan replied 10 months ago.

What if you have it unplugged when you do that?

Customer: replied 10 months ago.
nothing running, and I just stand on it and vary the pressure/weight i am applying with my bodyweight without moving the belt. I had the safety clip thing disconnected, but I will try again with the power totally unplugged when I get home tonight.

OK... sounds like it would have to be something related to the frame - or possibly the incline motor, even though it's not running at the time it's still supporting the weight. Please see if you can locate what part of the machine it might be coming from.
