Welcome to our forum.
It's inside the filter area, little octagon shaped doohickey. 6600-166 part # if I remember right. You can use a crescent wrench and unthread it from the shell of the spa. Pull the wire out cut and splice the new one on like speaker wire. Screw it back in and away you go. Sounds like the problem though. Other route you can take is open the front. Thin grey wires on the left, one is a flow switch, one is high limit, other is temp sensor. Splice the one in and toss the sensor end in the spa run for a few days to confirm that's the problem. If so, go up to previous instructions.

Looks like the HL sensor for mine is 6600-168.
No worries, and I should have said hope all is well life wise and welcome back it's been awhile! I don't remember the part# for the HL, doubt it's the problem rarely is in Jacuzzi's. Good luck on the fix, it's pretty easy. Let us know how it works out.
