Our VIP98 oven just refused to do anything this morning, no previous history of problems. Conveyor and heaters do not start up. None of the Solid State Relays in the back of the unit are operating, although we can make them switch by wiring up to t

Simon, In a previous life, I came upon a maintenance tech that had an old vapor phase oven control cabinet half ripped apart for a main power problem. I asked him if he had checked to see if any of the E-Stop swtiches had been hit. One had been ac

Tough call without seeing the board, but here's my best guess. You don't say if the glue dot is greater in height or diameter in the locations where you have printing (silkscreen), but I would guess that you might get either, or both, depending on ne
