Hi Everyone,
I have an 8 year old heater that does the following; can only be turned on and off by the breaker, when turned on, the temp display, pool light come on, it purges, lights (service heater light comes on) for about 20 seconds purges shuts off and the fault light on the underside of the board is AGS. I have put two calls in to pentair tech services, the first gentlemen did not inform me there was an error code on the back of the board, he told me to take out the thermal regulator and asked if it was corroded which it was, I put the plug back in and ran the heater without the regulator and had the same result, he asked me to hold down the pool button after the cycle, and because it showed the flue temp dropping he told me he was sure it was the membrane, ordered a new membrane and a new thermal regulator (since the old one was corroded and I had it out anyway) and installed both with no effect, same exact problem.
I called again and the first question the second guy asked me is the color of the display screen, he said red screens have the error code light on the underside of the control board, we ran the heater through a cycle and the AGS light lit up. He said the problem was the AGS shut off switch. I ordered the switch, today the switch came and although it has the correct number on the outside of the package the switch inside is the wrong one so I could not change it.
I looked at the diagnostic flow chart diagram and line diagram for the wiring, it says AGS replace auto gas shut off switch or high limit switch, since these are both normally closed switches I went out and jumped out the AGS with no result, I left the AGS jumped out and jumped out the HLS with no result. Since these are just normally closed switches and there was no impact bypassing them it seems like they may not be the problem. I hesitate to call Pentair again, so I thought I should turn to the real experts here at TFP, which obviously i should have done in the first place. The on off buttons do not work when it's running through it's cycle. I have put everything back together but I'm unsure what to do at this point, I could just call someone to fix it but would prefer not to. Since the buttons don't work and the membrane has been replaced could the problem be the control board? Any help is greatly appreciated.
