    The Saga of the Sta Rite Pool Heater... continues! :)

    Hello, Trouble Free Pool'ers! For those of you who have been around for a little while, I moved into a home in 2014 with my first ever pool. It's an older, massive in-ground concrete job. Anyway, the pool has come with a Sta-Rite 400NA heater which has been tons of fun. :) Background thread...

    Pool Pilot Salt cell not generating

    Hi all - sorry for the delay. I used to use strips, but found them unreliable, so I take my samples to the pool shop for testing. Most recent results (2 days ago): 0.0 fc 1.0 tc 7.4 ph 3200 salt 28 stabilizer (I added a box after the test) I had a test done a week prior and it showed 0 free...

    Sta Rite Pool Heater

    Hey - thank you as well, f3justusc - you saved me $200 with that "return to Amazon" idea! Without that, I'd have replaced the control board needlessly.

    Sta Rite Pool Heater

    Just a quick update: I've ordered the manifold bypass as well as two really neat brushes that look like they will do a great job. They're meant for cleaning aquarium pipes, and they have springs on the end instead of hard steel. I ordered one with stiff bristles and one with soft bristles, and...

    Pool Pilot Salt cell not generating

    Hi all, I have a Pool Pilot Digital with an RC-5 salt cell. I'm unfortunately making 0 chlorine even in Boost mode. Unsure of the age of the components as I've only been in the house for just over a year. Visual inspection of the salt cell shows things are clean - no build-up. I did a cell...

    Sta Rite Pool Heater

    Just a quick update: The bypass has been ordered and will arrive in a few days. My local dealer doesn't stock it and wanted $74 (!) plus 2 weeks to get it in, so Amazon got the business for $30 USD and 3 days shipping. Hate like heck to not support local businesses where I can, but the local...

    Sta Rite Pool Heater

    Nope... the pump is a 1.5hp single speed Sta-Rite.. The system runs at 21-22 PSI when the filters are clean, and around 25 when the filter is really dirty... except for when I have the system set 100% to the spa, and then it runs at around 30 PSI, as there's only one outlet for water in the...

    Sta Rite Pool Heater

    Nope, darn. She just died out again after about 45 minutes. Noise still... some chunking/banging after a while, and then "Service Heater" with AGS light underneath. Hm. So, let me recap what I've done so far, and what I have not done. Maybe there's something that I'm missing, here: - AGS...

    Sta Rite Pool Heater

    Hey everyone! Just checking back in... at long last, I had the opportunity to take the thing apart. It's cramped working in there, so it takes a fair bit of time. When I squirted water into the nozzles, there wasn't much of anything in there, but there may have been some sediment in the two...

    Sta Rite Pool Heater

    Today's the day - I'll be taking the bugger apart after work. Is there a "proper" technique for cleaning them out? Should I try and get a small brush (stiff wire / soft wire / etc) and use that to clean the tubes, or am I best off just using a garden hose with a spray nozzle? Last thing in...

    Sta Rite Pool Heater

    OH - sorry - you were asking about the regulator, not the bypass. It looked good, but it had that wrap tied around it so it wasn't moving freely. I did replace the regulator and spring 2 months ago... when I moved in, there was no regulator in there at all!

    Sta Rite Pool Heater

    Thanks a lot, Paul - I appreciate the reply! When I took the manifold off, the thermo regulator had that filter tie all wrapped around it. I took that off, but it seemed to work just fine and I couldn't see any breaks or anything. In addition to the two pictures above, I have these two that...

    Sta Rite Pool Heater

    So - control board received... though an interesting thing happened. My wife wanted to use the spa, so I turned the heater on (have not yet replaced the board). Ran for around an hour, then the heater gave the clunking noise again and died out, AGS light. I thought this was meaningful as I...

    Great idea. I'll be receiving the control board Friday!

    Sta Rite Pool Heater

    Thanks, Paul. So, I suppose we're past checking $30 parts and into rolling the dice on more expensive parts any way we look at this. My local service dealer only stocks a very limited amount of these and has told me that he needs to order either the ignition control module or the main board...

    Sta Rite Pool Heater

    Did you play the video I posted - and was that the sound you were hearing? I should note that the temperature didn't change when the noise was there, near as I could tell...

    Sta Rite Pool Heater

    Aha - found it - ignition control module, got it. Okay - so, given the order of part expense in ascending order, I'd like to check the thermal bypass first. Is this the same as manifold bypass, and is there anything beyond the obvious "wow, that's broken into three pieces" stuff I should check...

    Sta Rite Pool Heater

    Sorry for the delay - was out of commission for a few days. Thanks very much to you both for the replies. So, my question: How do I know if the bypass valve is bad? I took it out, there were no cracks and the thing pushed up and down properly, so it seemed like it was "good", but I really have...

    Sta Rite Pool Heater

    Rats. It ran for about an hour, then tripped to "Service Heater". I didn't hear the noise, which I suppose is progress, but something's not quite right, obviously. Pulled off the top - AGS light is on again. I have replaced both the HLS and AGS switches over the past year, and the previous...

    Sta Rite Pool Heater

    Okay! So, looks like we have a potential winner. Pictures attached... :) First - the backside of the manifold. Looks like there's something inside... Undoing the back part of the manifold, you see this: That's removed. Popped off the valve just to check - I think it looks okay - would...

    Sta Rite Pool Heater

    So - experiment conducted. The thermal regulator is pretty much brand new (I replaced it myself a month ago). I pulled it out and it didn't come straight out, but it was because something was caught - it looks like the wrapping on one of the pool filters (the paper cloth band that runs...

    Sta Rite Pool Heater

    Thank you! The heater was installed without a bypass in the system at all (seems kind of dumb), so water which is flowing from the filter *always* goes through the heater. I checked just now, and pressure out the returns is good. I'll do as you suggest and pull out the thermal regulator...

    Sta Rite Pool Heater

    Hi, everyone. Last year, I moved into a home with a pre-existing concrete pool and spa (both connected to the main system, separated with Jandy valves). Among its equipment is a Sta Rite Max E Therm 400 heater, which is the problem child today. The heater runs correctly when the system is...

    Sta Rite Heater Troubleshooting - part recommendation please

    *ARISE, DEAD THREAD!* :) So, I was unfortunately mistaken... my problem continues to exist. I went ahead and replaced the high limit switch and put a thermal regulator in as well just to be sure, but I still have a problem. Additional troubleshooting has revealed a few things: 1) I have a...

    Sta Rite Heater Troubleshooting - part recommendation please

    Looks like the AGS was my problem. Heater has been running for about 5 minutes without issue. The AGS looked like it was a little gunked up inside - I'm guessing that might have been what the culprit was. My pool place didn't have a thermal regulator in stock, but they could order one. I'll...
