Bernard E Weeki Wachee , FL September 05, 2016 Appliance: Maytag 30" Built-In Electric Combo Convection JMW9530DAS30 Maytag Oven Jmw9530das30: Fan was making noice. How to replace Oven Tangential Cooling Fan Motor. Replaced control unit fan. Note on this particular model (Jenn Air combination oven and Microwave wall unit) the entire unit had to be removed from the wall. In addition the Microwave top had to be removed to get access to the control compartment that housed the fan. Not a job for the fainthearted. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 1-2 hours
