Product review (1 stars): ERP means exact replacement part
You can get the OEM ( original equipment manufacturer) thermostat on ebay from an authorized whirlpool dealer for $17.00 and change. Don't buy this knock off that everyone is having trouble with or spend $60.00+ on the same OEM thermostat. The OEM part doesn't have the tiny adjustment screw people are mentioning, it doesn't need it because it's the proper part, made in the usa, by whirlpool for your fridge! Also be very careful not to kink the long metal probe when attaching the tubing. It's actually hollow and if you kink it, you're going to be ordering another thermostat and trying this again.
