The shipment of the replacement was incredibly fast. We found ourselves with a broken oven before Christmas. We diagnosed the Oven Thermostat as the problem. I will repeat the shipment of the new replacement part was quick. Removing and replacing the new part was less than an hour and eveything worked fine. Thank you!! 7 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
