I've picked up an older Cornelius Ice maker and want to put it into my shop. It begins making ice but never actually stops and goes into harvest. The one time it did actually go into harvest it never shut the water pump down so I just ended up with watery ice, while it was doing this I was able to check the outputs on the board and I found that the relay controlling the pump was stuck closed when it should have been opened. My question is this: Are there any Cornelius guru's on here and where can I find aftermarket parts for this thing? I've spoken with the factory and a new board is going to run me around $350 and I didnt even pay that much for the machine to begin with LOL. Any help would be greatly appreciated
