Nordictrack C1900 5 years old. Had been squeaking a little when on incline. About 4.5 incine would make it stop squeaking. 2 days ago the belt stopped for a split second while at 4 miles an hour.It was so quick I thought I tripped but knew it stopped.There was a slight smell after that happened.Sort of an electrical smell but also similar to a new macine when it first starts running.The next day abot 3 minutes into my walk ,again at 4 miles an hour the belt stopped.It didn't slow to a stop, it dead stopped.The smell was there when it started also. The entire control panel, fans etc... are working fine. Had the motor checked and it is fine also

Hi and welcome to FixYa,
Your description of smell and stopping after some time into the walk are very significant as both indicates that this is a heat related problem. Although the controller board and the 1.5HP motor drive have been checked, they would still be the primary suspects as they are the only 2 component that passes/uses high current to cause the smell and/or to stop the belt. Both should be load tested or checked in operation (not only passively). The proposed way of determining which (or truly eliminating both) would be to monitor the input / output voltage of the controller board and likewise the input voltage of the drive motor while the C1900 is in operation. The consistency/presence or absence of the voltages would point to the culprit when the belt stops.
Good luck and thank you for asking FixYa.
Hi again and appreciate your postback and additinal information.
Though the sub board may be faulty, it is doubtful if it carries that much current compared to the controller board. And if so (lesser current), then it would not heat up as much as the controller board and therefore would not cause the 'smell'.
I still am of the opinion that monitoring the voltage(s) on both the controller board and the drive motor would be the best indicator which causes the "twitch" (momentary stopping) and therefore by process of elimination would help you determine the faulty component. It is also possible to include the sub board in the monitoring. The only challenge in this fault finding method is the use of multiple voltmeters (at least 3). Determining the faulty component would be based on when the belt/drive motor stops:
- there is still voltage going into the motor, then it would be the motor;
- there is no voltage going into the motor but there is voltage output from the controller board, then it would be the connection from the controller board to the motor;
- there is no voltage going into the motor and there is no voltage output from the controller board, then it would be the controller board.
Similar monitoring / fault finding method may be applied to the sub (lower) board and all others.Hi,
Please double check all your connections. Check to see if you may have pinched any wire. Also check to see if you have accidently unplugged or pulled a wire loose. If that's not the case it sounds like a lower board issue. Place a regular 9 volt battery to the motor wires with the unit unplugged from wall and see if it moves. if not it's the motor, if so it's the lower board.
Thank you for contacting Fixya.com
Hi, the problem your having is with the belt itself often people think its the motor that has started failing but it is that the belt needs replacing.
The belts tend to stretch slightly over time causing them to slip on the motor this is the smell you can smell.
If their was no smell when it stopped then this would tell you that the motor has packed up but the smell is from the motor still turning with the belt slipping it causes heat and this is the smell you can smell.
With out the incline you wont have a problem as their is not much pressure on the belt.
Without anybody on the machine take it up to the incline your having problems at and you should see that the belt wont slip unless their is any actual wait pressing onto the belt such as a person on it.
The problem is replacing the belt and getting a new belt if you are not trained in replacing the belt then it can be a diificult task as you have to get the tension just right else it will slip exactly the same.
The best thing to do would be to try and contact the makers if you can and explain the problem tell them you need a new belt and see what they suggest.
You could also try a local electrical repair shop look in your phone book for these as they would be able to source the part for you and could work out cheaper than buying direct from the makers also they can fit it and offer you some warranty on the work they have done.
Sorry their is no easy fix for this as it is parts that need replacing their may be the chance of tightening the belt so as to take up the extra slack that has occured over time. This would need to be done by a profesional as it could cause you harm if it wasnt done correct and it could place to much pressure on the motor causing the motor to over work and fail.
I would contact local repair shops first and see what they suggest as they might be able to take up the slack and solve the problem but without actually looking at the machine it would be impossible for me to say if this is possible or if it is beyond repair.
Please contact repair shop as they can tell you for sure if it can be adjusted or if it means the belt needs replacing.
Let me know if you need further assistance ok.
This sounds very much like a loose connection. This could account for the 'electrical smell' too. Especially when under load (4.5 incline). The machine needs a good inspection of all connections feeding motor and associated circuits. When motor is pulling amps through a bad, loose connection it will create heat, and have a smell, that hot electrical smell...

Check if the floor is at level, or that will cause squeaking noise.
If this model has level adjustment at the back, then adjust threadmill level.
If the floor and the threadmill is at level, then the belt will need lubrication. Use the lubricant recommended by manufacturer.
If the problem is still there, then you will need a technician disassembling the threadmill to fix the problem. In that case better ringing the number listed on the owners documentation.
Yuor cheapest way out right now would be to lift the running belt as high as you can and shout some Pledge furniture polish under neath as evenly as possible. Then pull the belt around 180degrees and shoot some in from the opposite top side. Run the machine without anyone on it. And try it out. Thanks Dana
Your belt is either loose of off center. I could tell you but it is much easier if you see it done. This link will provide you with all you need to fix this. Follow the directions to the letter. http://www.iconservice.com/nordictrack/faq_tread.html#a2
Your machine is due a close look over and some maintenance. here is the link to nordic track which will tell you exactly how to proceed

One of 2 things, chances are its the bearings that support the belt and allow it to spin freely (should be able to buy parts). When a bearing goes bad it normally starts to squeak followed by a slight grind/rubbing then when it failes completly lock up. Usually when its going bad its not spinning smoothly and causing extra stress on the motor/belt assembly and the binding causes your burning smell from the motor.. When it seizes it will cause the belt to stop turning and the motor to slip/shut down due to not being able to spin the belt. This can also cause the motor to burn up as its trying to turn but not able to move. Most treadmill have system built into it that will shut the motor down when it senses a surge in current ( motor pulls more juice to try and turn when restricted). It could be one/both of these. I would go for the bearing first. When you pull the treadmill apart your may be able to apply power to the motor and see if it turns (or use a volt meter to test for reistance). Hope this helps
I noticed you had not accepted my answer, was my info not helpful? Did you have other questions that I can help answer?
Check to make sure belt is not stretched out and may have slipped It is also possible that the rooler may have stuck for a second. The smell could be very possible that belt was turning and roller wasn't and brunt for a second. You can grease roller edges or bearings with spray silicone, WD40, or equivelant.
