James C Chandler , AZ March 28, 2015 Appliance: Whirlpool 27" Electric Double Oven RBD276PDQ4 Whirlpool Oven Rbd276pdq4: No power. How to replace Oven Thermal Fuse. Tested the power source and kept testing until I found it. Thermal Fuse was burned out after 15 years. Not bad for the amount paid for the part plus shipping ( under $25). Double Oven is as good as new ! Well worth the research on-line... Maybe it will last enough 15 years. 2 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
