Hi all, I hope you're well? We've just bough a treadmill cheap as it had a fault and we want to repair it. After investigating the circuit boards I can see that 2 resistors are burnt out. I have attached pics. Problem is, how can I identify what resistors they are to replace them? All help greatly received.

 

You can probably still measure them. They do not look destroyed. More like they overheated and burned up the pcb and traces..

What is the fault? Some feature not working, no power? You are going to need to do some more work then just those resistors.

Thank you for your reply. Yes we agree we have several jobs after this. The resistors are bad and need replacing, we're just not sure how to identify the correct replacements. The fault was the motor would start to run and then stop. Thanks again.

 

I can not tell the colors well enough to give you an idea sorry. Might be a good idesa if you listed out the colors as you see them.

 

What is the model number of the board?
Max.

Thanks for your reply. Here's the model with number.

Cheers, Robin

 

Unfortunately I don't have anything for that number for the Horizon, Did you measure them, as they look the same value?
Are they connected to any power device?

They were both open circuit. They appear to be connected to the height motor.

 

In the absence of a schematic, you may have to do some reverse-engineering, starting with the motor technology for the incline motor.
This will give an idea as to the type of semiconductors used.

did you remove them to check them or checking them in circuit?
