How to Troubleshoot & Replace Samsung AP5727517 / DA81-05884A Refrigerator Water Filter Housing Assembly

I replaced it, along with the Water Inlet Valve for good measure. The how-to video was amazing with the details I needed to ensure I didn't miss any steps. Without the video, I'm sure I would have missed something or at the very least, the job would have been harder. Something as simple as putting a hose connector on correctly (hey, you have a 50-50 chance), was not a concern when having the video to reference during the work. It took me about 45 minutes to complete and that's taking my time to be thorough. There have been no leaks and for the first time in a long time, the fridge is working correctly, with a filter installed. 

Replaced the water filter housing assembly with a new one from appliance parts pros. 

I disconnected all three water line on backside of refrigerator and water line to water dispenser, removed old water filter housing assembly located at the bottom interior compartment of the refrigerator. I installed the new filter housing assembly, new filter and reconnected all four water lines. turn water supply on, checked for leaks and vented air from new assembly. Perfect 1/2 gallon per minute water flow discharge from dispenser. Problem solved 

I replaced the water filter housing with a new OEM unit that I ordered from AppliancePartsPro.com. I followed the video instructions provided at the referenced website. There were two differences in my refrigerator (from what the video showed) that made my job a bit more difficult. (1) The orange tubing for the ice maker was routed with the tubes for the filter housing assembly through the conduit. The orange tubing then bypassed the filter housing and passed with the tube for the water dispenser, down and out to the opening behind the kick plate. Because the orange tube was secured with small cable ties around the thermal/air insulation around the 3 other tubes, inside the conduit, it was necessary to pull that back out, cut the cable tie, and cut away the old insulation. The same had to be done where the orange tube and tube to water dispense passed into conduit on the floor of the refrigerator. I used small crosscut snips to cut the ties, and then scissors to cut away the old insulation. (2) The new assembly came with a clear molded cover over a step at the top front of the assembly that I didn't notice until I was finished. (The old unit didn't have that cover.) The clear cover blocked the full insertion of the bottom drawer, so I had to partially remove the filter housing in order to pry off that clear cover to allow the drawer to slide all the way in. This is not a complaint, just a "heads up" to others doing the job. 

With my hands.
