Aqua Hot Control Unit
Well, once again, Aqua Hot problems. just had to replace the high limit sensor and still wont fire up. Local repair guy (factory trained) thought it might be the control unit. So he replaced it with his and burner fired up. When he replaced mine and gave it a "slap", it too fired up.
So, apparently one of the relays in the unit is hanging up. Question: has anyone found a source for "rebuilt" units? Or can the box be opened and the bad relay "fixed"? New one is $770.
Looks like I can leave the system case open and go slap the control unit when it hangs up, but don't know how long this will last until the relay goes totally kaput.
