I have an Hayward H400ED1 pool/spa heater that has been bullet proof for the past 14 years. This week it seems to have stopped working. It does not ignite. Water pressure is good and I have confirmed that the unit is getting power. I am assuming that there is some fuse or switch that is faulty because the unit stopped working one night, then worked fine the next day, then again it worked then stopped working with no other changes to the system.
Guess I am just looking for some items to test before I call a pool company out to fix it.
