just FYI - the new 2024 Raypak 406A has slightly different dimensions than my old 2006 406A...

Thanks. The previous owner professionally maintained (~$2K/yr) the pool for 6 years after construction, but the copper heat exchanger was leaking well before the end of that time based on the extensive corrosion and the salt system had completely failed. My wife has handled the chemistry in...

Thanks; so far I've found no standardization of the vendors' geometries. I've been unable to find any other vendor that might be a drop-in fit except possibly an elevated Lochinvar ERN402. Does anyone have experience with those? Are they much more reliable than Raypak or Pentair? While...

My Raypak digital 406A heater was professionally installed in 2006; when I bought the house in 2012 the 406A was already leaking and very badly corroded, I have had to repair it many times for a variety of failures. My experience with Raypak support has been extremely poor. It is now time to...

It was fairly easy to modify an igniter from my old broken Craftsman propane barbecue to replace the 007864F for my 406A; now the PC board gives no error messages. The other issue, where the main burners would sometimes cut off at random times when heating, then immediately relight after the...

One uses the tools one has at hand. I'm well aware of the limitations of the tools I use, whether it's a $10 DMM or a $500M linear particle accelerator; in this case a $800 DMM wouldn't serve any better. I once taught an undergraduate course that covered that issue. At NASA I had better...

Thanks again J. You're quite right - if there's a "Flame w/o CFH" message there should be a current and there is. With the igniter connected to the board, my red DMM reads 0.8 uA while the board is reporting "Flame w/o CFH"; so the board is behaving perfectly, doing what it should. With the...

Just minutes before this problem appeared, when the pilot was running flame strength showed 8 (good). Intermittently, though, the pilot & main would turn off and flame strength would say 0 - those occur so close in time I can't tell whether the board lost rectified current 1st and then shut...

Thanks for your replies. It is the same heater, but having just been laid off due to sudden large NASA budget cuts to space radiation research, I'm trying to squeeze a little more life out of it while I look for another job. With the whole igniter entirely removed from the heater, if the...

A very weird problem with the Raypak 007864F igniter in my Raypak 406A spa heater has arisen; I'm wondering if anybody else has seen it. The control board always reports "Flame w/o CFH" even with the bare igniter entirely removed from the heater & pilot assembly and grounded only at the small...

According to the Raypak instructions, the Fireman Switch is an optional switch installed across pins 13 & 14 on board connector P2 required in certain jurisdictions and is not the same as the 2 remote Demand Heat inputs on connector P1. Perhaps other vendors use different terminology; this is...

Thanks again for your advice. There never has been a Fireman Switch installed, but it's a very good idea to check that the nothing has broken @ the P2 connector - thanks. The original board from 2006 failed in 2015 such that it always reported Demand Heat even with P8 to the Jandy system...

Thanks for replying. Just to be clear, this Raypak board has separate settings for SPA Set Temperature, SPA Max Temperature, POOL Set Temperature & POOL Max temperature. The SPA & POOL Max Temperature are safety limits and have never been changed from their default 104F value. The SPA &...
