I order, received and replaced the heat exchanger for my Hayward H250FDP heater (water leaking). The heater is showing LO even after I jumped of the pressure switch to confirm it was not that. After doing some more reading it says that it's the Temerature Limit Switch. I was looking for the proper one to purchase also any advise on what else it could be if not this. Thank you.
