Colin F Bethesda , MD June 14, 2015 Appliance: Model JBG605SET2SS Burner knob would not rotate I have a GE Adora gas stove. Its a JGB605 model. The knob for the font left burner would not rotate. After looking through the manual, the parts lists on the internet, and checking some youtube videos I decided I had to replace the valve for the burner. It took maybe 30 minutes to disassemble the stove top. You will need a Torx driver. Swapping out the valve was trivial and reassembly was quick. I am always amazed that there are instructional/DIY videos for every possible thing on youtube!! The burner is working fine now and I probably saved $200 on a repair call. 6 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 1-2 hours
