Pool Timer Running Erratically

[Sparrow910]

Hey pool masters. A few weeks ago I noticed my pool pumps coming on at akward times of the day. When I checked the timer, it was not set to the correct time of the day. Reset it, and checked it once a day for a few days. Seemed to be about 10 minutes slow per day. But somewhere around day 7, it jumped to being several hours off. I'm working with a grasslin (Grasslin by Intermatic FM1STUZ-240U 24-Hour 21A, SPDT, 240V Electromechanical Timer Module - Wall Timer Switches - Amazon.com ). Do you think if I get this replacement from amazon and install it, my problems will be fixed?
Thanks!

Welcome to TFP.

Yes, just replace it. The mechanical internal mechanisms wear out.

Ok great thanks. Looks like an easy install. I should be ordereing a 240V timer right?

I have not seen what you have installed to say. You need to match up with your existing wiring.
