I use a 2477SA 240-volt controller to turn my dust collector on and off. It recently went silent and dark, with no indicators, no indication of life. I cycled power to it to try to reset it, but there was no change. I did a cursory visible inspection of the circuit board and didn't see anything overheated or discolored. Does anyone have experience working on this model and/or suggestions on things to try to bring it back to life? I checked with Insteon and they no longer make this model.
Thanks,
Jim K.
