Found Oven unit off, customer advised that conveyor sped up after being on for awhile - they shut unit down and later turned unit on and worked okay, checked wires at pick up and speed control board, did not find any loose, ran unit for 1/2 hour - please get price pick up and speed control board ( top oven ) Note: gave price of parts to John, he is not sure if he wants parts ordered yet. Closing out this work order.
