Pull the Jenn-Air refrigerator away from the wall so you can access the rear of it. Unplug the refrigerator power cable.
Remove all screws on the rear panel of the fridge and take off the rear panel. The internal components will now be exposed.
Look to the bottom of the refrigerator to locate the drip pan. Remove any screws on the sides of the pan.
Slide the pan toward you and out of the refrigerator. You can now clean and replace the pan or slide a new one in its place.
