Product review (1 stars): UPDATE - part only lasted 4 months
UPDATE -  Part only lasted 4 months.  Ordered another part that was OEM.  Had to pay a little more for the OEM part
My fridge wasn't cooling but if I tapped the control knob it would kick on.

Fixed my problem.  My refrigerator was intermittently not staying cold.  Was relatively easy to change after finding videos online.  Took a day or so for the new thermostat to settle as it initially was too cold.  All is well
