I have a burnt resistor I can't make out.

I already took a look at this schematic and it is not the exact same for my treadmill. The R21 on my board is 510 while R21 on the schematics is 100. Does anyone happen to know values of R21?

 

There a many versions of the MC2100, so you cannot go by the print.
I will see if I have a LS-30rev

The colour code on the R22 measures around 110 ohms, the colour on R21 jives with the measured 500ohms.
