Question about Jandy Laars Lite2 Ld 400,000 Btu Heater
All test points have acceptable voltage except will not energize igniter. Power control board is expensivr to replace on a guess.
If all voltage test points are within range, then it's 1 of 3 problems: Power Conversion Plug is faulty; Power Control Board is faulty; or Controller is faulty. Jandy says there is no way to test any of these directly. They recommend that you replace both the Power Conversion Plug (~$35) and the Power Control Board (~$230). Apparently when one fails, it can cause the other to fail as well. They said that unless the Controller has a lot of corrosion on it, then it probably is not the issue.
