Fresh water sentry problem

[aggies09]

My fresh water tank sentry alarm is screaming at me. The tank level is fine (full). My limited diagnosis is telling me that I have a problem with the Headhunter Tank Sentry. Is there another area that I should be focusing on? Is there a way to test to see if that is indeed my problem?

I turn my switches off to shut off the alarm.

Not enough info to help, but if you have the level sensor book that will help with trouble shooting. I had to clean the sensor tube and recalibrate the one in my holding tank, did it per the book and it was easy to do.

I did not empty and fill my whole tank, but used a deep small container that only took a few gallons of water to calibrate. It works on the pressure of a column of water, not volume.
