Product review (5 stars): Replace it yourself and save MONEY
Worked great. My oven was running 50 degrees low.  My wife ruined 2 baked items and told me she was done cooking until I fixed it. This gave me plenty of motivation to getter done.  I removed the 2 screws holding in the sensor and a few on the back center cover.  Un-plugged the old one and removed it.  Feeding the new plug through the insulation was the toughest part.  Taped it to a screw driver and pushed it through and plugged it in.  I put it back all together and now the oven temp is dead on what ever temp is selected.  Don't pay for a $150 service call, do it yourself!
