Good day! I opened my pool last week, got everything working including the heater (had to clean out the tubes before it would stay lit, but was working fine yesterday). I have an older (17? years) Hayward H250 propane heater. I went to turn it on this morning, as the pool is still pretty cold, and it ran for a couple of seconds and then poof, went dead. Seemingly no power at all (digital display dead, no error codes, no lights). Checked all the breakers, and they are fine. Any ideas what might have happened? Is there any srt of internal breaker? There was something that looked like an automotive fuse on the control circuit board, but it seemed intact. I DID replace the control panel keypad last year with a non-hayward one (I had done that 4 years or so before, too, as the buttons had gotten very touchy). Is it possible that has died and it is causing this? I can replace that easily enough. I realize the heater is due for replacement some time soon, but if I can avaoid replacing it right now (and be able to swim sooner than I can get a replacement) that would be great! Also, the new hayward heaters have the inlets at just over 13" and mine is at around 18" so I'll also need to redo the piping and fittings, which is another reason I'd like to fix it for now. Any thoughts? I am reasonably handy. I was trying to get voltage readings internally and I only seemed to get them in a few places, but I was unsure what might be switched and what was unswitched and therefore would not be affected by a wonky control panel. I attach a photo for reference.
