The defrost timer was defective David D. • Sherman, TX • July 08, 2014 Appliance: General Electric Refrigerator TFS26PPDABS My Repair & Advice Got on AppliancePartsPros.com and they had the exact part number. Ordered part on Friday via second day shipping and I got the part on Monday. Finally I did not have to manually turn the switch on the timer every so many hours to defrost the refrigerator. Thanks to the Pros my refrigerator is defrosting itself now... Easy to look up part and model numbers with their system. Excellent. Was this review helpful to you?
