    Easy Touch temperature sensor

    My Easy Touch is about 2 years old. The OEM water sensor went bad in March.

    I replaced it with an aftermarket versions (Optimum Pool Technologies) and replaced it in March, and the replacement failed a couple of days ago.

    The air sensor is still accurate and the on-roof solar sensor seems to still be working.

    Luckily, I ordered two to have a spare, but after installing it, I'm wondering, are these sensors problematic? or am I having bad luck? or could something be wonky with my install? or ... ?

    May be too close to the pump and getting too much pressure maybe during priming.

    And yes they fail. I have replaced mine once in three years.

    Re: Easy Touch temperature sensor

    Have no idea if blakeusa's answer is correct (seems plausible), but I experienced the same phenomena. I have all Pentair equipment - air and solar still working after 3 years - water sensor near pump failed after 2. My pool install has reasonably simple plumbing - usually running the VS 3050 @ 900 RPM, stepping up to 1350 RPM when the solar is demanded (only spring and fall here in Florida).

    They appear to be a 10K thermister in a plastic body. Can some of you tell me exactly how they fail?

    They fail to report temperature accurately. Not sure exactly how they fail since I haven't taken one apart.

    First failure reported the pool to be a steamy 105 F in march.

    Second failure reported the pool to be a tepid 70 in July when it was 85F
