Ron Y Millsboro , DE July 24, 2015 Appliance: Whirlpool Refrigerator GR2FHTXTB00 Whirlpool Refrigerator Gr2fhtxtb00: Leaking water filter housing. How to replace Refrigerator Water Filter Housing Assembly. It's bit of a chore in that on my Whirlpool Refrig you need to remove the grill on bottom front and the Utility Panel on bottom rear. Then unscrew the original filter housing and pull it out through the back of utility opening. Remove the two water hoses and put them into new filter house. Reverse the disassembly process to reinstall new filter housing. I'm old and slow so the process took me about 45 minutes. (Note: Unplug electric and turn off water inlet before starting.) 20 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
