Robert J Kingston , TN June 26, 2015 Appliance: Model JENNAIR 42" SIDE BY SIDE (JSF42SEFXDA)? Freezer defrost was not working I checked continuity on the thermostat and it was closed at room temperature when it should be open. I ordered a new one from AppliancePartsPros and I hope it solves the problem. Since the icing sometimes doesn't start for weeks after thawing and deicing the freezer, it's too early to tell if the problem is fixed. I do want to take this time to say the AppliancePartsPros website and their handling of my order is the best experience I've ever had with Internet shopping. The website works vey fast and effective, and with standard shipping the order was received the next day! THANK YOU!! Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
