I had this fix performed today. Whirlpool set up the appointment for me. When I explained the fridge was in an RV, the tech reserved the right to back out. I said okay, let's do it, it's a 2 man job. Here's what we had to do. Bought 2 milk crates and 2 light moving blankets. Removed the fridge drawer front panel (4 screws). Removed the fridge wheels cover. Removed the 3 screws holding the fridge in place. Removed the top right door top hinge cover and hinge, Lifted the door off. Removed lower door hinge and lower right wheel assembly. Pulled the lower wooden cover off from below the fridge and unplugged it. We had to pull the cord and water feed from foam insulation/sealant. Tied a pull string on the power cord so it wouldn't sneak away. Placed 1 moving blanket on the floor and placed the milk crates at the outside edges of the fridge. Pulled the fridge out slowly and slid crates under the side frames. Placed the other blanket over the front of the fridge. When it was about 2/3 out, I pushed the bathroom side of the fridge out more than the front side. This twisted the fridge and allowed it to be carefully slid out to the edge of the back. It's really tight! The tech removed the back cover (6 screws) and installed the new P-trap. Reversed the process and it's done. Total time - Less than a hour. It can't be performed by 1 person. No more water on the floor during auto-defrost cycle. All under warranty of the fridge.
I tipped the tech $20 for sticking it out with me. He really wanted to quit twice. The hardest part was figuring out the process. The fix took less than 1 Minute!
