Hi all, I am new to the forum and new to S.W.G. My system in 4 to 5 years old. I just purchased the house this past january. My pool pilot ran well until recently. I replaced the SC 36 cell, now the error message reads bad temp sensor. It never gave me this error before. It actually gave the message before I replaced the cell. My question is, Is there a way to check the sensor? The cord is plugged in at both ends. Do I but a new sensor? Any suggestions?
