4 yr old all Jandy system
Aftwr replacing the salt chlorinator i found i couldnt control my JXI heater with my iaqualink I could turn on the heater manually but when in remote mode nothing And the heater light wont turn on the motherboard /electrical panel i replaced the thermostat on the heater but nothing
Salt chlorinator wont turn on because it isn't getting message the water is warm enough to work
The Jandy support said it was likely the 7790 Temperature Sensor. (I checked all cables nothing frayed or broken so guessing just worn out inside)
Has anyone replaced these before? It sticks into the pipe - is it as easy as pulling out the old and sticking in the new? How do you ensure it doesnt leak? (I see how to do the electrical part and it looks easy)
will the non oem ones fit? They are about 1/4 the price but I just worry about leaking
 
It one of the easiest parts to replace. The new one should have a seal on it.
Tune off power to the AquaLink system and remove the old one from the board and the pipe.
After removing the old, lightly clean the pipe and around the hole to remove any build up. Lube the new one and insert it. Ensure the clamp is in good shape or use a new one. Make the 2 wire connection on the AqualLink board.
