Product review (5 stars): Cheaper than a service call
Just what I needed even though I wasn't sure at the start.

When I inserted a new filter I got no flow through the water dispenser on the fridge. After removing the filter I could see a slow drip coming from the filter housing. After researching a bit online it seemed like the housing itself was a common failure point so I took a shot and ordered it. I figured it was cheaper than a service call.

After removing the old housing I dismantled it and found the reason that one no longer worked. You could see the valve stop for the filter input was weakened by years of water flowing past it. See pictures for more info.

It took less than an hour to install the new part and I didn't even have to access the back of the fridge.
