I emptied refrigerator and freezer, and left freezer door open for 36 hours, as an alternative to taking apart the freezer compartment to clear the ice around the condenser, and in the drain hole. I removed the back panel from the refrigerator. Be careful-- the edges of the sheet metal cover are very sharp! I disconnected the harness that was looking at me, with the push-on connectors (stick a screwdriver in middle, and push.) Took off the old duck bill check valve, and installed this kit. Take a long thin screwdriver to get at the clip holding the bottom of the old drain chute on, and push it in and down, carefully, through the fan to your left. It's a little hard to get free. Kit fits great. Note: Some of the old info has 2 different p-traps. This one fits either size fridge.
