I have a well maintained but older laars Jandy lite 2 NG heater. I need replacement new or used for the heater control assembly R0366200. I have looked low and high and the one or two that may be in stock around $500. I have gone through the diagnostics from the manual and all voltages etc check out. The lcd screen like everyone knows who has this deteriorated over time. I can see just enough to see no service error codes and that when I go to try and turn on pool heat the symbol stays off. I have done a reset of system. I do not have it set up with timer to the pump. And no spa setup. So is pretty streamlined. The button for off/on is about gone. Not sure if anyone has any shortcuts. All I want right now is to get it heating and I will manually shut off. It worked fine one week ago. I believe I have done all the known troubleshooting but I am wide open to any suggestions from a quick fix just to fire it up or a reasonable source for replacement board. I previous post recommended a company that rebuild Jandy boards but contacted him today and this board is not repairable.
