Watched your repair video for Oven temperature sensor.
Ordered new GE sensor from your site.
Replacement made according to video, including door removal.
Tested oven to 425 degrees, opened door to bring temp down to 390 degrees.
closed oven door and temperature rose back to 425 degree setting, as it should.
Issue resolved.
Oven temperature sensor received was a exact replacement for older GE Profile Spectra Convection Oven.
The Video was simple and straight forward.
Next repair will be the convection fan motor.
