Delmer L Dewey , AZ August 26, 2021 Appliance: Whirlpool Refrigerator WRS325FDAW01 The push button switches were hard to activate to change from water to cubes etc The new Ui assembly that has all new push buttons. I found the water shutoff and the power plug when we pulled the fridge out. I shut off the water and pulled the AC plug. The whole assembly that is being replaced, came out easily when I pushed two small tabs on the lower part of the old asm bottom left and right. I used a small screwdriver to release one and then the other tab. I disconnected the electrical connector and the old unit was free. Connect the power plug to the new unit and slide it into the space where the old one was. Easy to replace.
