I have found this forum to be extremely helpful to troubleshoot my system, but need some feedback from experts. My pool is 5 years old and my Jandy system is the original equipment, except that I replaced the cell and only the cell last summer.

My system has stopped generating chlorine, and is giving error codes 180, and 172.

We removed and inspected the cell, it seems fine. We removed the sensor, and one of the three sensors was a little oxidized, so we cleaned it with a green scouring pad, and replaced it but this did not solve the problem.

Now thanks to the troubleshooting help found here, I followed the instructions for determining if the board is bad or if the sensor is bad. When I pushed the R-temp and salinity buttons (w sensor disconnected) while pushing salinity button on front, I did not get the 2.8gpl readout - I still had the chlorine production setting displayed; likewise, when pushing the other button combinations, I did not get the temp readouts indicated, but still the chrloine production setting readout.

This leads me to believe that the board is bad per the troubelshooting forum. However, just would like some confirmation from those in the know.

I am also debating whether the $320 investment in a new board is the right one given that the other components may fail in the near future as well. Thoughts?
