With the doors fully opened, lift up the base grill. Tilt the top of the base grill away from the refrigerator. Set the base grill aside.
Attach the 1/2-inch socket to the ratchet.
Inspect the arrangement of the bolts located in the area where you removed the base grill. The bolts located to the inside of the door hinges are the leveling bolts. The top bolts adjust the back of the refrigerator, and the bottom bolts adjust the refrigerator’s front edge.
Adjust the leveling bolts as necessary with the 1/2-inch socket attached to the ratchet. Turn the bolts clockwise to raise the corner or counter-clockwise to lower the corner. If you notice the head of the leveling bolt pushing away from the face of the refrigerator as you loosen the bolt, re-tighten the bolt until the head pulls back flush. Switch to the other corresponding bolt to adjust the level of that side of the refrigerator.
Install the base grill after you have leveled your Whirlpool side-by-side refrigerator. Set the bottom edge of the grill in-place and push the top edge of the base grill toward the refrigerator. Slide the base grill down to lock it into position.
