Replaced a 10 hour timer, but the shorter 6 hour interval has not caused any problems and is the current recommended, manufacturer specified replacement for my Kenmore 253.68882018 refrigerator. Easy to replace - watch the online videos; the defrost timer is in the front of the refrigerator section on this model.
When your timer doesn't advance anymore, it can be stuck in either the defrost mode (no cooling) or refrigeration mode (ice buildup in freezer section which also clogs the vent to your refrigerator section, making it warmer). The manual fix is to turn (advance) the defrost timer with a flat screw driver blade to get it out of the current mode. I had to do this until I got the part.
