Product review (1 stars): Quit after 5 months
I bought this part in August, 4 to 5 months ago. It quit working a week or two ago.  When I installed the thermostat I had to dial it in all the way to the left below the 1 on the dial to keep everything from freezing and it worked fine until now. This is not a Whirlpool part it is a "ERP exact replacement parts" part no. ER2198202.
