The AutoPilot has died, not just the cell. We've replaced the cell twice, the power cord once (could be the problem again-"amps low" message) but the plastic viewing panel has broken and water got inside, we think. If it was just one problem we'd try to repair or fix it, but it's 6 or 7 years old with multiple injuries. We were also looking at the Compupool system but have seen some bad reviews. Sure is a good price, though.
