I have a Jandy LRZ40EN heater on my pool. I've had issues with keeping the heater running until it reached the desired water temperature. On most occasions, the heater will initially turn on, but after a short while, it will turn off and not go back on. I've recently replaced the Flame Sensor -- so I know that's not the issue. I don't see any error messages on the heater and our water temperature sensors are reading the correct temperatures. If I open up the heating unit and wiggle random wires (I know --not the most scientific thing to do) -- the unit starts back up. Go figure!! Anyone have some thoughts on what this could be? Is it the pressure switch? Any troubleshooting advice will be greatly appreciated!!! Thank you.
