Hey guys let’s not go to raggin on my RV Tech he is good at what he does, I guess I haven’t relayed all the facts but the parts he’s replaced were bad ie ciurcut board had corrosion on it from moisture and sail switch was bad both tested bad but apparently there is another problem not detected yet, and it’s intermittent and we all know how intermittent problems can be hard to diagnose. Trust me he’s not throwing parts at it and I wouldn’t let him but sometimes things can be a real pain to get working right.
