Sensi-Temp
Ben,
When I bought my house back in 1996, it came with my 1966 GE 40-inch P*7 range. The Sensi-Temp burner was not operating correctly. The burner size selection buttons worked, but the burner had only 2 settings -- off, and full on (red hot). Unless you were boiling water, it wasn't very useful.
I decided to try fixing it in 2000. Back then, GE had a dial-in help line where you could pay for appliance troubleshooting. They first recommended replacing the sensor, which did not fix the problem. They then recommended replacing the responder, which did fix it. I wonder now if the sensor was okay, and only the responder was broken?
