James P Bowdoinham , ME December 09, 2016 The oven heating element failed during preheat I removed the oven door by removing two screws, shut off the circuit breaker, unscrewed the element from the oven wall, withdrew the element to be able to disconnect the power leads, and then installed the new element and reassembled the oven. Easy. Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
