Hi all!

A few weeks ago, our timer stopped working. I had an extra set of trippers, so I changed them out. No help. Changed the on/off time. No luck. Ordered new trippers. Nada. The timer will go trip ON, but not off. It’s like the timer just stops working when it gets to the off time (but the pump stays on). Our pool will be 3 years old in the fall, so the timer isn’t what I’d call “old”.

Any ideas? My next step was to buy a new one. But wondering if I should upgrade or change brands. After some very basic Googling, it seems like this *may* be a bit of a problem for others.

As a side note…when the pool was being built, they did accidentally cut some type
Of electrical line (that was pool related). We were told it was fixed. But not sure if this sounds like it could be a side effect of that? Just so strange that it worked up until a few weeks ago.

Pic of the timer blurb in our pump housing box attached.

Thanks for any thoughts/advice!
