No LED lights on for my Aquarite SWG t-15

[dlbondy1]

Hi there. I have a Hayward AquaRite Goldline SWG . It is 11 yrs old. My problem is no LED lights show up in the display. I have just replaced the "display board", and replaced a new T-cell 15 and still have no LED lights which means that my SWG is not functioning. I am using chlorine tabs for now.
My question is why? Would a faulty flow switch cause the problem of no LED lights or do I need a new Main PCB? I have replaced the main PCB board once after 5 yrs. I live in MA and open my pool end of April thru mid Sept. Any thoughts, suggestions are greatly appreciated. I'm thinking I may need a new PCB board. Thank you so much!

When you say display board, do you mean just the LCD screen or whole main board?

If you are getting no red/green lights then most likely same issue I had, need a new thermistor.

Hi thanks for getting back to me. No lights at all on display screen. The thermistor is the round piece that needs to be soldered? I don't know how to do this. Is it easy? It's a much cheaper fix!

Look at the Wiki linked above for the Thermistor location.
