Unfortunately, electronically controlled equipment is not 'intuitive' and knowledge about one heater is not very helpful in troubleshooting a different one. I've never worked on a Jandy so I can't help you.
The manual is here:

I'd recommend working through their trouble shooting guide, and then calling Jandy AFTERWARDS. That will help you move up to a Level 2 tech -- the Level 1 guy will likely just work you through that manual, but over the phone.
You might also post your question at poolspaforum.com . That site has a lot of pool guys -- just ignore their chemical advice, since you're likely to get pool-stored, electronically. (Waterbear from here also is active there; his chem advice will be OK).
