I'm having an issue with my treadmill , it worked fine for 2 hours then blew the electrics, when I turn it back on it blows I've. Checked the plug and it is fine , I unplugged the motor and the treadmill turns on but shows lines on the screen , I've changed the carbon brush and still no luck , I've also plugged the motor into a car battery and it runs slow with no issues , could someone help please ? Thank you !

 

So first, what is the board type?
Post photo .
It could be a myriad of reasons different makes, different problems !??

 

It's a MAXXUS run max 7.1
I've included some photos of the circuit board i can try and take it out if better ones are needed ! Thank you !!

 

Not familiar with that model, unfortunately,
If it blows right away without any control issued, I would check the DC rectifier circuit etc.

 

No problem , thank you very much !
