I have a GE Monogram Advantium 240v Speed Oven and I love it (it is about 2 years old ... ZSC2201). A few months ago I got an error message saying "Upper Thermal Sensor - Service may be required". The microwave mode still worked, but there were issues with the Convection Bake function and oven temperature.

A technician replaced a sensor, but I don't think the Convection Oven is working properly yet. It takes a very long time to preheat, and a manual thermometer placed inside the oven indicates temperatures that are different from what I am trying to preheat to (sometimes hotter, sometimes colder). Questions: (1) Does anyone have experience with this particular error code? (2) If anyone has the Advantium 240v, can you time yours and tell me how long it takes to preheat the oven to 350 degrees?

I appreciate the opportunity to tap into your experiences. Many thanks.

I have the same unit and have gone through this as well. There are a number of TCO‘s.(Thermal Cut Out) or ( microwave thermostat) If you look at the attached files you will see where they are located. You will need to replace additional TCO’s to get it to start to pre-heat. I need to order more for my unit as mine no longer heats up for convection/bake, and now my speedcook has done the same. For the first 5 years the unit worked great, now every 6 months I am replacing these TCO’s. From what someone said it could be the Magnateon that is causing it to over heat as it is going bad.
