Raypak Model P-R406A-EN-C NOT Lighting....

Hi everyone!

GREAT SITE !! So GLAD I found it......

Newbie pool owner here, and need a little help. I have already looked at various threads on this, and tried as best I could before asking for help here.

Raypak MODEL P-R406A-EN-C Natural Gas heater. I think its 400k +/- BTU.

Purchased/Installed end of last August with new pool. Only used a few times last year before closing pool. This year since pool was opened, NO PROBLEMS with it ! All of a sudden, not firing.

I have gas, pilot LIGHTS! I hear click PRIOR to pilot lighting - but when its lit, I just hear clicking, clicking, clicking. ERROR CODES were Ignition Failure. I cleared codes, reset to factory defaults, no visible rust/etc on burner tubes. Nothing around heater changed in way of wind, etc. Simply just won't fire. I'm pretty mechanical, so if any suggestions, please advise. I guess if any of them I get do not work, I will have to bite the bullet and call a tech.

Thanks in advance for ALL of the knowledge on here, and the time everyone takes to answer my question!!! Greatly appreciated!!

Best regards - Bill
