Thank you for posting your question here on Fixya.com.


It should only take a few minutes to actually replace the part; quite a bit longer to diagnose the problem depending on the way the switch failed and overall condition of the heater. It would not be unreasonable to get a bill for an hour to troubleshoot and repair a heater with a defective high limit switch.

Yes you can jump past the limit switches one at a time. That will tell you which one is bad. Then you will need to replace it.

Jandy Lite 2 Pool Heater won't stay lit


This could be a number of things, high limit switch, temp sensor or clogged burners. If the heater does not get much use cob webs could be the culprit. To test the high limit switches you can disconnect them temporarily and use a jumper wire , if it fires and stays lit then you have found your problem. Just disconnect the 2 wires , and use a separate wire to connect the two together bypassing the switch. This is a safety feature and should only be jumped as a diagnostic tool and not left to operate this way.
