First I want to thank everybody for the help and suggestions fixing my Jet 16/32 drum sander. Yesterday I called a local electronic repair shop and spoke to the owner, a retired electrical engineer. After explaining my issue I took the SandSmart controller to see about a repair. Not sure if everybody knows but the PCB has a fuse on it.He said that was blown, didn't give me a reason. After about 45 minutes it was repaired and he said it was functional. Total coast: $53.63 and about an hours time. Cost for the board through Jet: $303.86 + S/H. Just an FYI if your conveyor quits working...
