My bottom-freezer refrigerator has an L55-30F thermostat. Can I replace it with an L140-30F thermostat that I happen to have?
Answer Chris, No, don't use the L140 -30 F thermostat. Use the proper part WR50X133. The range is triple the temperature range, you'll create other issues with the defrost cycle and cooling of the refrigerator if you do.
