Depending on which Whirlpool appliance, the model number can be easily found on the inside surface of the appliance. The model numbers are generally found inside the drawer or on the door of kitchen appliances, and on the rim of the door for washers and dryers.
The likely location of the model number plates on Whirlpool ranges and wall ovens is inside the oven drawer on the rim. The microwave, dishwasher and trash compactor numbers are located on the inside rim of the door. The refrigerator model number is inside the refrigerator on its inside wall. Washing machines have the model numbers beneath the lid on the rim, and the clothes dryer's number is inside the dryer door on the rim.
