My Jandy Legacy heater is not working, and the display shows "Fault - Shorted H2O Sensor" and "Water:212o Set:104o". I understand that means that the temperature sensor is bad and needs replacing. It's a salt pool and the manual lists two parts: R0477300 (salt) and R0456500 (regular). I tried to find the the salt part online and several sites said it had been discontinued and replaced by the regular part. Is this true and is there really a difference? Also, can someone point me to instructions or a video on how to test to see if it's really the sensor and how to perform the replacement? I have a multimeter but have no idea where to start! Thanks.
Jandy Legacy Heater Temperature Sensor Replacement (what, how, etc...)
- Thread starter pooldadd
- Start date
No difference between either of them. Not even sure why they thought back in the day they needed one for salt. No other company ever did that. Just replace with the regular one.
Thanks! As for actually replacing the sensor, will it come with instructions or what is the best source for how to do it?
No I don't recall it comes with instructions. Here is the manual to help you.
