Sewing machine power board

Robert A:
Hi hive mind. I’m trying to fix a sewing machine power board and I’ve found a power resistor that’s blown. I have a circuit diagram (IMG_0056) and the resistor in question is R10 2.2ohm 3W. Firstly what is its function? Is it current limiting, voltage limiting or something else? IMG_0056, for illustration purposes only, shows the type of resistor in the circuit but at 47Kohm obviously I can’t use it. Can I use, nearest value wise, this resistor that I have got, in IMG_0058? What would it’s impact be on the circuit if I were to use it?
Bryn:
I don't see the images attached (as your post was supposed to refer to them). Could you try reuploading them please?
Robert A:
Sorry about that, don’t know why it didn’t attach them.

Is it possible to get the rest of the circuit diagram?  It would be good to see what those power rails are powering.

Here’s the full circuit diagram
