Jeff H Grand Rapids , MI January 24, 2016 Appliance: KitchenAid Gas Range KGRT607HBT6 Kitchenaid Range Kgrt607hbt6: Error code on kitchaid stove. How to replace Microcomputer. Went online to ApplicancePartPros.com. Webchatted with a specialist. Gave him my error code and stove model number. And within 5 mins. I had the replacement part ordered. This was on a Sunday and the part was at my door by Wednesday. By wednesday night the parts were switched out and our oven was working again! Probably saved us 200-300 dollars by doing it ourselves! 3 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
