My freezer is freezing up and will not get cold enough.I replaced the defrost thermostat in the freezer compartment and the defrost heater element works great, it glows red, but I have to start the defrost cycle manually holding down the temperature controls inside the refrigerator compartment to get my electrolux/frigidaire model LECR23EFE0 refrigerator to go into defrost cycle.
