Kenneth C Tolland , CT July 28, 2015 Appliance: Jenn-Air Self Cleaning Slide-In Electric Range JES8850AAB Jenn-Air Range Jes8850aab: Range dual surface unit would only go on in "high" setting not on any other settingsje. How to replace All Purpose Appliance Cleaner. Replace dual infinity switch. The only difficulty is the terminal labels on the new switch did not match at all with the terminal labels on the original switch. The enclosed instructions were NOT helpful. But I contacted your representative, Johnny, and he was most helpful and patient. From my model number he located very specific and detailed instructions for how to wire the new switch. The rest of the job was easy. Your representative was outstanding. Thanks. 25 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
