Product review (3 stars): range sensor

Let me preface this by saying the new part did not fix the oven problem.  What was  disturbing was that the new sensor made the problem worse.
The temperature difference with the new part is greater than with the original(old) part. The actual oven temperature with the new sensor is 125 degrees less than the digital temperature setting you set.  Didn't want to go through disassembling so left the new sensor installed.  The initial difference in temperatures with the original sensor was a 75 degree difference.  Wonder about the quality/functionality of the new sensor.
