Tizzle I have a top mount Whirlpool refrigerator that I've changed the timer and put the black jumper onto connecter 1. I've noticed the freezer would melt everything and freeze it back up again so I changed the timer again but to a universal one with no jumper. Would this be okay and what does that jumper do and do I need it for this refrigerator or not. Thank you
Answer Hello Tizzle, This is more likely to be a defective defrost thermostat. The job of the defrost thermostat is to open the circuit to the defrost heater when before the items in the freezer are melted, (normally about 50°F). The defrost timer will just cycle the defrost circuit in and out for a specified period of time. The defrost timer matters as long as it is for the same defrost intervals and defrost times.
