Symptoms of a bad Defrost Timer include:

• Frost buildup in the freezer compartment
• The refrigerator or freezer is not maintaining the set temperature
• The fridge or freezer sections are too warm
• The defrost cycle does not activate, leading to reduced cooling efficiency

This OEM GE part can also be used on Hotpoint, RCA, and Kenmore/Sears appliances.
