Treadmill repair Testing The LCB Lower Control Board

Treadmill repair Testing The LCB Lower Control Board...
I am a retired fitness equipment installer and repair technician. I will be producing a series of videos on safety, maintenance and some repair on treadmills. The treadmills I have on hand are a Nordic Track, Horizon, Sole and a cheap off brand. If you or anyone you know (please, for them, consider sharing) has a treadmill, consider subscribing so you or they can get updates to the videos on safety, maintenance and some repair.
There is a few things to narrow down that will help you decide if the LCB (Lower Control Board or Motor Controller Board) is bad.

You just saved me some money!! That hair dryer worked like a charm.

[@blightreign]

Super glad i came across your channel!

Mike, Great diagnostic tip with heat gun. Always pays to think outside of the box!

[@johnwoodburn6182]

Mike - good video, keep it up! I have a DC motor Proform that starts the walking belt and it stops 2 seconds a Or so later with no load. I loosened the belt, not it.

[@jayr4413]

Will a bad capacitor cause the treadmill not to power on ? I open the cover up and you can see it blew its in little pieces ?

[@markymark3730]

Hi Mike, I'm troubleshooting a Sole F63. I've unplugged the cord from the LCB going up the console and checked for voltage on all pins in reference to ground and got zero on all pins. I know there is good voltage going to the board and I do have one green LED. Should I go ahead and replace the board ? Thanks

my pro form ifit top LCD Controll panel had no power won't turn on, but the bottom control board did had power, what the isssue ? please help

[@jaym48]

Do you get a LS1 error when it does not start? Are you saying you found the Root Cause being the Capacitor; however, the Control Board is not able to have replacement parts so an entire board is required? Here is my current issue. Any feedback would be very appreciated: I have the F63 (SN 56381415....). It counts down from 3, 2, 1 and then the display says 0.5 mph but the motor/belt is NOT moving. 5 seconds later the console reads LS1 error. ALL Console controls (fan/incline) work/display before the LS1 error appears. The Control console can also alter the speed display but does not do anything to the motor. I disconnected the motor from the Control Board and used a 9V battery as a source of power for the motor to determine if the motor is bad. The motor runs. I then validated that the incline Up / Down lights on the board work as the unit is calling for an Incline command. I then found the PWM light and observed it when I pressed the Start button. The PWM light turns ON but then turns OFF about 5 seconds AFTER the 3 second countdown hits Zero. I attached my Multimeter to read voltage off the Control Board, after I disconnected the Red/Black motor wires for the Battery Test and did NOT read any D.C voltage when Powered On, during the Start/3 Second Countdown, or up to the LS1 error. I do not hear any "clicking" during /directly after the 3 second count down and not sure if there was a Relay that should do that or not? Note: I noticed a green LED light all the time above the motor connection on the board. It appears to read Motor DRV. There is another LED light, not on, next to it that reads "Shut Down". Any recommendations would be greatly appreciated.

I have a pacemaster pro elite motor willstart but real slow and wont speed up. Any load causes shut down and error code

[@gm32801]

Hi Mike. Do you have a replacement lcb, model T-335HR, Trimline

[@marshaharp9958]

Would you recommend trying anything else besides this? This procedure produced the exact same results you show in your video. I assume that means the control motor board is bad. But would you suggest continuing to try other sensors or wires?

[@davidho1590]

Thanks for the video Mike, I used a hair dryer to heat up the capacitor and it worked 😊 but have you figured it out the reason for this?

[@WhatIsMikeMakingNow]

I have not. The boards are throwaway, so I just bought a new one.

[@rickc2222]

@@WhatIsMikeMakingNow there are a couple repair shops you can send them to, sometimes saves a bit over new. sometimes they upgrade components too and it's better than new.

[@kevintaglich5659]

Hey Mike, thanks for the video. My Nordiktrack treadmill starts and belt moves for a few seconds then stops. Incline motor and display screen work fine. Tried this suggestion and unfortunately no luck. Any ideas? Thanks I would appreciate it

[@WhatIsMikeMakingNow]

Look up Treadmill Doctor's website. I think it is your lower control board. They will confirm it for you.

[@martinlutherkingjr.5582]

Why not just replace the capacitor?

[@onemoreboat]

What would cause the red motor wire to burn itself off of the control board where it attaches?

[@luigicirelli2583]

the transistor might be faulty, like shorted, so won't act as per instructions from the PWM and pass unrestrained all available current to the motor, effectively overloading the connector, wires, traces; take the transistor off the board, follow a test procedure accordingly to model, replace it with a matching model.

[@stephen8304]

I have a nordictrack T6.5s almost identical to the machine your working on in the video. I was hoping you could help me or shine some light on my issue. I moved my treadmill, plugged it in and nothing at all--wont turn on. I took the hood cover off the bottom and I see a red LED and a green LED lit up but the top control panel will not display or light up, any help is appreciated

[@WhatIsMikeMakingNow]

You most likely have a bad motor controller.

[@stephen8304]

@@WhatIsMikeMakingNow thanks Mike! I tested it and it seems good. I do have power it seem to the top console but no power to saftey key. How would I rule the console being bad

[@WhatIsMikeMakingNow]

@@stephen8304 how did you test it?

[@CoLdBLaDe]

Where is the best place to buy a control board? I need one for a nordictrack e3200. Amazon’s treadmill doctor listing has it for $270. Seems high to me

[@WhatIsMikeMakingNow]

Try going directly to Treadmill Doctor

[@grithog5399]

Could it be a bad capacitor if it always runs, but the speed slows down intermittently?

[@seadude4869]

No, that's something else. The cap is there just to start the motor, it does help the motor runs.

[@myenglishprofessor9189]

I have a NordicTrack Commercial 1750 about ten years old. Yesterday, she pooped out on me. No power at all. Checked the outlet, popped the canopy, and the LED on the controller board does not come on. Is that a sign that it’s time for a new control board?

[@serialmahogany]

Would love some help too. Having the same issue Nordstrom T6.5z. Brought a new cord, the whit connector looked burnt. New cord installed and lcb still doesn’t light up. Treadmill still doesn’t work lcb or console.

[@myenglishprofessor9189]

@@serialmahogany new controller board fixed mine. Super easy to replace.

[@dukedadson774]

Hello Mike are you still Training i want to signup for the kindly reply me

[@seadude4869]

just solder the cap out and replace it with a new one. it's very easy to do and a lot cheaper.

[@briangbur8743]

What happened to the national Assembler network

[@WhatIsMikeMakingNow]

I sold it and the new owner ruined it out of greed and not giving back to the techs.

[@btcruiser31]

You can't just replace the capacitor on the board??

[@seadude4869]

yes, you can. It is easy and much cheaper than to replace the whole board.

[@richardparis8738]

Mine doesn't have a capacitor

[@WhatIsMikeMakingNow]

They all have a capacitor.

[@mrbroons]

Hi Mike, great video, learned a lot. I have a funny issue with my Sole F63, the motor will start and run for a second and then stop. I have a video I've created on this, any thoughts, is it the control board? kzbin.info/www/bejne/parPhmZorbx2hq8

All I can see basically is your silhouette next time you do a video try not having your garage door open behind you.
