Jack H Jonesborough , TN April 03, 2021 Appliance: Whirlpool 30" Electric Range Ceran Cooktop Convection Oven GR450LXHT2 Whirlpool Range Gr450lxht2: Our oven was turning out underdone baked goods. How to replace Bake Element. The stove is about 19 years old. We had a difficult time getting baked goods to be cooked on the inside as well as outside (bundt cakes especially). I replaced the oven temperature sensor probe, used a digital oven thermometer (as well as the older type) to measure the oven temp. The older, dial thermometer hit and pretty much stayed at the set 350 deg F. The digital one showed a plus/minus 20-degree fluctuation and all seems well. We haven't baked a bundt cake to test, yet, but we will soon. I believe it will turn out as it did in years past. 4 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
