hi have looked at your site and error codes I think my problem is the oven temperature sensor but not sure oven does not start to heat at all as soon as i push bake or broil I get the f4 and beeping on my display. I have opened the back of the oven and i see where the sensor connects to another wire that goes up to the clock display but i'm not sure how the two plug separate i pulled gently but the two did not come apart I was afraid to pull to hard and rip the wires out of one side or the other is there some kind of pressure sensitive release on the two plugs?
