Product details
The CMP 25280-100-930 is the dial assembly for the PowerClean chlorine feeder. The dial is what sets the feed rate, metering how much water flows across the tabs in the chamber.
Why it fails
The dial is the one part of the feeder that gets handled regularly, and it does that while sitting in direct sun above a chamber full of chlorine. Over a few seasons the plastic goes brittle and the drive detail strips or cracks. The symptom is a dial that spins freely without changing the feed, or one that seizes at a single setting.
Fitting note
It is supplied as the dial assembly, so the whole control comes out and the new one goes in. The listing covers the PowerClean Ultra and Mini, and the manufacturer text names the Ultra, so on a Mini it is worth comparing the part against the feeder before you commit to the swap.
