Product review (3 stars): The actual part I received did not have the thermistor ...
The actual part I received did not have the thermistor connector in it.  The 220 part is supposed to have it, whereas the 210 part is not.  Luckily, I was able to pull the thermistor connector out of the old part and into this new part.  Other than that, this part worked to replace the old defective valve.
