pilot light won't light on pool heater

[Isshin]

I'm with Poconos on this one. The first thing I would try is cleaning out the tube and orifice. This has happened to me twice before and that was the fix - best of all if it works its free.

Other issue might be the pressure switch, you might want to try jumping it and see what you get.

I'm not 100% sure but I think the pressure switch and all the other interlocks should prevent the main burner from firing but the pilot should still work. I may be wrong though.

No Al, you're right - the pilot is before the safety switches.

A spiderweb in the pilot tube could be enough to prevent the lighting.

HOWEVER! When I run into this at work - I back off and have the pool owner call their gas company to find/ fix the issue! I know some about this stuff, but I don't want to be responsible for blowing up someone's house!

I strongly suggest NOT to play with the internals/ gas piping, unless you are a qualified professional!!

Let's all be safe!

well guy's you were right :-) the pilot light tube and/orifice was clogged. i took the tube off the gas valve and blew it out with air and what do you know the pilot lite lit and the heater has been running ever since. thanks again for the help. Randy

Yippee ! Another no cost and easy fix. Just took time to find it.
Happy Heating.
