This DIY repair guide gives step-by-step instructions for replacing the dishwasher vent and fan assembly. The vent opens during the drying cycle, and the dishwasher fan exhausts hot air through the vent opening at the bottom of the dishwasher door. If the dishwasher fan fails, the control panel goes blank and the dishwasher stops in the middle of the cycle. Replace the vent and fan assembly with a manufacturer-approved replacement part.
Use these steps to replace the vent and fan assembly in Kenmore, KitchenAid, Whirlpool, Maytag, Amana and JennAir dishwashers. You also can use the same basic process to replace the vent and fan assembly in some GE, Frigidaire, Electrolux, LG and Samsung dishwashers.
