My drum sander's conveyor recently quit. We were able (with help) to narrow down the problem to a component on the speed control. My husband said he is willing to attempt to solder on a new component (a new circuit board is over $240) but after considerable web searching, I have been unable to find one. It might help if I knew what it was called so I could more easily narrow the search.
Here’s a photo. Can anyone tell me what the square, gray component on the lower left of the circuit board (indicated with an arrow) is called?
Thanks for any help you can render.
