    Leslies copper therm heater. ( Raypak RP2100)

    My heater displays a SNS on the LCD.
    After some research i determined that this is a bad temp sensor.
    I went to leslies a bought a new one for 100 bucks .
    Removed the old one and noticed it was split.
    Installed the new raypak part, the connector was different, had to use the old one , soldered and heat shrunk connections. Now i still have the SNS error !!!!!

    Any body got any ideas ??? PC Board ????
    Thanks for any help !!!!

    Heater back on line !!! Got the correct temp sensor online ..
    I Forgot we had the PCB replaced a few years back .. It maters on what sensor you use ...

    Bought a new PCB for my raypak rp2100 digital , on E-bay for $ 85 bucks and it works !!!
    My LCD was going out .. They still have some more if anybodys looking .. He had a case of them new old stock.
    And also i used silicone to seal the bezel , it's plastic and the sun warps it a little letting rain water in ..
    And it gets on the board .. The boards are going for around 300 in the pool stores .
    Might get a spare !!! A few years back we had Leslies fix the heater he changed the board out for around 700 bucks , 5 min job .... For me.. And that was my first one ..
