I have already talked to the manufacturer and so has the owner. They offer no assistance whatsoever. They tell us that it is some type of surge that is burning up the timer board, However, They don't have any idea of what is actually happening. They just replace the timer board and return it.
The owner now has it plugged into two daisy-chained surge protectors.
How would the isolation transformer work? Would that be a 120/240 transformer with an isolated ground, or what?
