Jonathan L Burtonsville , MD August 16, 2014 Appliance: Model ET20DKXSN01 Refrigerator stop running until i fiddle with the defrost timer Suddenly one day my 27 years old refrigerator stop running. I put my finger in the defrost timer adjustment slot, and tried to turn and it was running again. I had to do that almost once in 2 or 3 days. My wife told me to trash it, since we have a newer refrigerator in the kitchen. I ordered part from AppliancePartsPros.com, and it arrived in 2 days. I replaced the part, and past 3 days it runs without hitch. The part I ordered was almost same as original part except old part had two back wires to connect to selection terminals (I had to pick one terminal since new one only have 1 wire to terminaln and I pickterminal #2), and also had ground connection since it had metal cover (not like all plastic cover on new one). It was missing two nuts and I had to dig out from my old tool box. (That is why I could not give out 5 stars) Other than that it fits perfectly well and took about 20 minutes to replace the timer including about 5 minutes to find those two pesky nuts.. 20 bucks well spend, and Job well done. 13 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
