WP12729128 - Whirlpool Refrigerator Defrost Heater

This Whirlpool Refrigerator Defrost Heater (WP12729128) is a genuine part designed specifically for Whirlpool, KitchenAid, and Maytag refrigerators. Also known as a "Defrost Heater Assembly," it plays a crucial role in your refrigerator's defrost cycle. By melting frost from the evaporator fins, it ensures proper cooling efficiency and prevents the buildup of ice that can impair refrigerator performance. If you notice your refrigerator is not cooling evenly, frost is accumulating rapidly, or the fridge is cycling more frequently than usual, it might be time to consider replacing the defrost heater. It's important to unplug your refrigerator and, if possible, safely store any perishable items elsewhere before starting this replacement. Remember to wear work gloves to protect your hands during installation. To ensure compatibility, please check your refrigerator's model number before purchasing this part.
