Steven S St. Joseph , MO September 29, 2014 Appliance: Model HMG213727A Refrigerator wouldn't get cold I replaced the defrost timer. It's a 27 year old Montgomery Wards refrigerator and I couldn't find the correct timer anywhere until I contacted AppliancePartsPros. Great service. 5 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
