Hello everyone! I have a proform 705 cst treadmill with damage to the motor controller. The damaged component is a resistor called R42, which is burnt out.
I would like to change it but I don't know the power value and can't find any datasheet about it.
Can you help me?

 

if someone who has the same mdoello as me could post a picture of their board so I can get the little number above the resistor

 

Hi,
There are likely to be problems elsewhere associated with that resistor.

Good luck............

 

Hi, thank you for your reply.
Maybe the problem is a short circuit on U9 (I attach photo MOC3052) and Q3 (I attach photo S8025L).
I have found and purchased these two components, I will repair the faulty connections on the PCB but I cannot find the value of R42 that blew up.

 

Hi, I have a similar problem and have opened a post

That does not appear to be a MC2100 series, if so I am not familiar with too many other makes.

 

Yes it is a mc2100els.
I attach photos.

The last photo with an orange arrow drawn is where the damage is, the R42 resistor

 

I think I had mentioned that was one I had not seen, do you know what part of the circuit it is in?
Function for that part of the circuit?

 

Currently my treadmill turns on but the carpet does not move. If I press to increase the speed, it increases but the mat still does not move.
The incline works.
Checking over the two parts already changed, I noticed this burnt-out resistor.

 

Hi,
Nice pictures.
Have you looked for secondhand boards?
I'm not suggesting to purchase, but to study any pictures to see if R42 will reveal its value.
MaxHeadRoom is very good.
Good luck.........

"It increases but mat does not move"
What increase's?
Does the LED blink steady?
