Aquarite - replaced varistor - now stopped again

[KNIGHTCAP]

I have an Aquarite SWG. I've replaced the mother board twice in 8 years. It went out again this summer - no power light but the display works. This time, I bought the varistor or inrush current limited from Digikey and soldered it on. This worked -- the power light came back on and it generated chlorine. However, it only lasted about 10 days -- now, the power light is out again.

Could I have another problem? If so, why did the initial part replacement work? Am I looking at another board replacement? Any reason why I would replace 3 in 8 years?

Thanks for any advice!

It could be lightning taking it out.

Have you looked at the limiter to see if it's burnt or broken?

Perhaps your soldering skills were not up to par ?

I would take the circuit board out and double check the soldering job, then the Inrush Current Limiter.
