A bad Sensi-Temp burner can be repaired; new parts are still floating around eBay and John combo52 has some used ones.
The major items are the sensor, which you can see in the middle of the burner, and the responder, which is in the control panel. Neither is cheap.
However, take it from a Sensi-Temp owner, the feature is well worth having. It is wonderful to have precise heat control selectable by temperature.
This model was available in a self-cleaning version. It was not the TOL, even with the P*7, but it was a darn nice range.
If I were you, and wanted a yellow GE range and Sensi-Temp, I'd let this one go by and wait for one with P*7 self-cleaning. The luxury of not having to clean an oven is worth it, in my view. The range you brought me from Wausau has transformed my cooking habits from nil back to normal cooking now that I don't have to worry about the chore of cleaning.
A Sensi-Temp burner can be converted over to a regular one, but you have to ask John combo52 what's involved; I'm sketchy on the details.
If you found a 1966 GE 40-incher like Dean's (robinsondm) in yellow, you would probably be deliriously happy with it. This is Dean's range and Dean's photo; it's a 1966 J 486. This was either the last or next-to-last year that yellow was available, but it was available: [this post was last edited: 1/19/2014-15:26]
