Vicki N Medford , MA March 06, 2016 Appliance: Model GE RANGE JGB918SEL3SS The middle section of the knobs were broken and we couldn't turn on the burners The replacement parts (control knobs) fit perfectly. 2 minute fix. The online Chat person assisted me in finding the part. I had tried several other websites and stores that did not have the correct part and could not help me find the correct knobs. Parts arrived in 2 days. Excellent service Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
