I have a wood worker and last night I went to turn it on and nothing completely silent I checked the power cord for power , checked all connections, pulled out the switch as I have in the past for dust build up and it’s clean , checked the in line fuse and appears to be good but I noticed in side on the big silver box there is a real faint green light that flashes slowly any help would be appreciated as I have a cribbage board to complete for a customer

Hi Mike - Welcome to the forums. I don’t know for sure, but I think the “big silver box” is the power supply. Are you sure the estop is not engaged? Recommend you check the incoming power and the output power from the power supply. Report back – hopefully we can help.

-Tom
