Fix treadmill motor control board of Nordictrack Proform 400 MC 2100LTS-30 How to Repair motor

The resistance value of the resistor is GREEN BLACK BROWN ORANGE (500k) 1/4 watt it is a 5 band and the tolerance is BROWN, I replaced it a little bit higher than 500k because the store don’t have exact value of 500k

Nice video, On the 2:00 minute mark of this video you were testing the voltage coming out of the board ad it was about 2 volts and dropping which determined the board was bad, what was the voltage after the repair? (on Terminals A-- and A+) Thanks!

[@kbmblizz1940]

Good work. I'll share this I learned, mine had both Control Bd and Motor problems, perhaps related. A bad motor may cause the bd to overheat leading to early death. I replaced the motor and still wont work, so I just rigged a cheap dc spd controller on it and it works now. Motor test using dc battery is very basic, mine ran too with it, but one of the rotor coil (measured by ohming the opposing contact pads) was bad. Symptom NOISY, overheat, draws too much current. Wouldve been better to buy another treadmill than replace motor and cntl bd. It was a Proform, but NT similar.

[@weecanduweet1096]

I would suggest to recoil your treadmill motor but that’s a lot of time to consume.You were right, bad motor causing the board to working harder or overheating and that’s what happened to this treadmill it starts from the motor.but Since when I fixed this treadmill until now is still running good even though we using it 3x a week.anyway thanks for the comments and sharing some of your knowledge and I learned about it.

[@kbmblizz1940]

@@weecanduweet1096 Thanks for your video man. I searched hard for this topic. Ny 2hp motor had melted insulation floating inside, but still spun-up. A new motor was $250 w/shipping, repair cntrl bd was $200. Might as well buy a new or find good used mill on craigslist. 😝

[@weecanduweet1096]

What I did so I can fix the control board was I troubleshoot all the resistor coming from the main supply(HV) that regulate into 5v who supply all the small IC’s. I hope you still can fix your control board. Voltage drop test is very helpful to me in this video that’s why I found the problem. When I do the voltage drop I found out there’s no 5v supply to those small IC’s that supposed to. I took time and patiently fix it bcoz I know how value the price if you buy bd or motor as you said $200 and $250 is not a joke I’d rather buy new one too or from Facebook marketplace 👍🏽

[@nitrousman8882]

Thanks for sharing this. I have a treadmill that the motor can, at times be easily stalled. Typically after running for a while or at low speeds. Can this be the motor controller or more likely weak Permanent Magnets in the DC motor?

[@weecanduweet1096]

it could be bad windings of motor or weak power supply. T

[@nitrousman8882]

@@weecanduweet1096 I wouldn’t think windings would be “good torque” sometimes... sluggish others. Not sure what a weak power supply is... bad caps?

[@weecanduweet1096]

Possibly. But I never encounter yet a bad capacitor from treadmill but most likely in the cpu power supply and tv’s.

[@flynbyeya]

Nice work! I wish I knew as much about this stuff as you do! I'm currently trying to fix my mc2100lts-30. Whenever I got start on the treadmill the motor would try to run at full speed for a half second before shutting down. Supposedly it's a problem with the MOSFET IRFP250N. I'm about to replace it and see what happens.

[@weecanduweet1096]

It could be the irfp250n and it is very important here to use multi-meter and do the voltage drop so we not guessing. I hope you can fix it. 🤙🏼

Hi I have the same problem can you fix for me My trade mills power board not working

[@mogomega8825]

Very unicue video, thank you for sharing. Can you tell me where the blue wires goes from the motor?

[@weecanduweet1096]

I wasn’t really pay attention on that blue wire when I was fixing it because it’s not related to the problem but what I can remember is that blue wire is a AC Line ,from input AC goin to the motor and going back to main board. If I’m not mistaken that’s the thermal sensor for the motor it goin shutdown when it reaches over temperature the DC MOTOR

Hi, I just watched your video and it is helpful. I am in process to diagnose the problem with my SOLE F63 treadmill. I used last spring and after that I did I didn’t use it. The power was connected to the machine all the time just safety key was removed. In this machine when safety key is removed the display won’t turn on. I went this week tried to put safety key but no display. I am not sure its problem with board or display. I opened the motor cover looked at it there is green led that lights up when the power is on. But no display. I am not sure if any moisture in the basement air caused it or may be power was on all the time caused it. I have little video that I can share with you to get your opinion. Please let me know if you can help me by looking at the video and give some ideas. Thanks

Try look those ribbon or line how to the display

I have a bad capacitor but having trouble finding a replacement. 1500mf/ 200 volt

[@macgyvercamacho7472]

I have the same board and I don't hear the click when I turn on the treadmill so I'm thinking it's a relay but which one ?

[@weecanduweet1096]

They didn’t use relay switch into that design they only using the optocoupler and a transistor as a switches

[@alfredjamesdemesa2586]

Boss how about some problem, like treadmill run only in 3 to 5 seconds only. Please 🙏

[@weecanduweet1096]

There are many reasons why it became like that. Try look if there’s some loose connections or maybe weak components like resistor or capacitor. I hope you can fix it

[@wisnupurwanto5322]

Hi Bro Very nice video. My treadmill Nordictrack T14.0 is having problem - relatively new, only 2 .5 years old. I wonder if it relate to the motor controller problem. 1, Initially the TM worked well for approx 15 minutes; then the walking belt (I didnt realize) move to the right and the TM stopped, re-start, loading the menu on the console and ready. 2. I tried to start again manually but the TM immediately stop and trips the breaker or blown the 13A fuse in the power cord, every time I start (manual start). Seem the motor withdraw very high current. Practically the belt does not move or move very little (mm). 3. I have aligned the belt, lubricate and reduce the tension of the belt but no success. Same happened. 4. The incline function is working well. No problem to up and down to maximum (12 deg.) 5. No problem on the other console functions. However, every time i start, the TM immediately stop and trip the breaker or blown the fuse. 6. There's very small movement (fraction of second) before immediately blew the fuse. Seem like the belt stuck. However, I can easily move the belt by rotating the motor pully. 7. I removed the drive belt from motor pulley. The problem still happen - blew the fuse but I can see that the motor pulley rotates for few seconds. Is there anyway to identify what part is exactly making problem? TIA

[@weecanduweet1096]

I wonder if it’s bcoz of the mechanical that something is tight. To determine if it’s either belt is the problem or the motor reason why the fuse is blown is try to detach the supply line goin to the drive motor and observe if it still the fuse will blow

[@wisnupurwanto5322]

@@weecanduweet1096 Thanks again, You're the man. Seem the problem from the motor. I detached the supply lines (red and black) to the motor from the controller, the fuse is not blown. I dont think it is the belt problem as the fuse is still blown when i detached the drive belt from motor pulley. The motor is Leili, 3.0HP, 130VDC / 2238 watts. Is there anything I can do rather than to purchase new motor?

[@wisnupurwanto5322]

@@weecanduweet1096 Thanks for advise. I'm not sure if I can open the motor and check the magnet. However, I did check the resistance of the motor is 1 ohm and OL to the ground. The resistance will increase if I rotate the pulley. From my understanding, this indicate the motor is okay.

Try check diodes or regulator transistor if your fuse keeps blown
