Alan S Friendswood , TX September 05, 2015 Appliance: General Electric Free Standing Microwave SCA1000DWW03 Ge Microwave Sca1000dww03: Ge advantium oven quit working. How to replace Tco Base Hood. My GE Advantium oven would just shut off as soon as you hit any button to start cooking, whether it be microwave or advanced cooking. I narrowed it down to the TCO (Thermal Cutoff). I found the part and hot wired it to verify the oven would cook again. I ordered the part and within few days had the new part. Once I replaced the TCO the oven works great again. Wife is happy and saved me $1000 dollars. Do-It-Yourself Rating: Repair Time Estimate: 1-2 hours
