Jandy Lite2 controller blinking and can't program

I opened my 24' round pool last week and when I started up the Lite2 it worked. The next day I noticed that every graphic on the controller panel was blinking. I tried some of the keys and none of them worked. There are no error codes flashing (because all the graphics are blinking).

    Bad controller was my problem. From now on I will be disconnecting my controller and will be bringing it inside my house out of the cold climate here in Canada. It's just 4 screws and a ribbon cable. Hope this helps other Jandy lite 2 owners.

I had the same problem and a friend of mine told me that the board is shot and needs to be replaced. I got a new board and installed it just now and everything is working fine now. The back of the board looked a little fried. If you can take the board out which is connected by a ribbon cord and plug and 4 screws on front. It might be possibly fixed by an electronic person or else you will have to get a whole new board $275. Sorry

My heater is turning on automatically without the Jandy controller being switched on. It was working for the last two years, and now this starts happening. Is it the computer board on the heater or is it...

I would call the Jandy technical support line at 800-822-7933 and they may be able to help you determine the next step. I hope this helps.
