My Jandy JXI control pannel lights up with no errors but does nothing else. No blower fan, no lighting clicks. I opend the side pannel and dont see anything obvious (Burnt wires or burnt circuit board)
Any ideas before I call comeone out to repair? Anything I can check?

Lots you can check if you have a multimeter and know how to use it to check voltages and continuity.

May be a blown control board or Fenwal module.

@setsailsoon had a thread on diagnosing his blown JXI heater.

Also, I can hear the LED light transformer kick on but no light. Should I just replace?

Replace the light or the transformer? You need to check the voltage output of the transformer to the light. I don't believe in shotgunning parts replacement without proper diagnostics.

If the Fenwal is toasted like that chances are there is other damage as the current found its way into the Fenwal.

Let me emphasize Allen's point about shotgun replacement of parts. That can get very expensive especially on that heater. When you see a board that's like it has had a forest fire on it yes replace is likely needed. If not, do some diagnostics. Lightning can be very frustrating because it can do very weird things. If you check everything out and still can't find an error run a temporary new power to the heater all the way back to the breaker. In my case lightning had caused almost microscopic perforations in the hot wire that caused enough leakage to ground that it interfered with the micro-amp current to ground needed in the flame sense circuit. So I kept getting the IGN error even after replacing several components that were obviously fried but not the ones that tested good. I came very close to replacing the blower and the control board that would have cost well over $500 before I ran the temp power wire. When I did that everything worked perfectly. $30 of wire was a lot better. We sold the house eventually but the heater is still going strong almost 10 years now.

I hope this helps.

PS In the interest of safety and abundance of caution let me hasten to add don't mess with power supply unless you're qualified. It can kill.

There was obvious damage to the Chlorinator circuit board. Replaced with Amazon parts and is good. Timer Intermec motor replaced

Red,

I forgot to add, Welcome to TFP! Sorry you're starting with this kind of problem. Also, know you're in good company here. Most of us got here trying to find a solution to a problem and often frustrated with service providers that just want a big bite from your wallet that doesn't make sense. We have experts in everything that volunteer here to help pool owners like you. And one of the best things about TFP is we sell nothing so any advice you get is never conflicted with trying to sell you something.

I hope you solve this issue quickly and please follow up to let us know how you fixed it. We're all always learning!

Chris
