Lori H Acton , MA October 20, 2018 Knob broke on my 13 year old Jenn Air range :( I ordered your: Gas Valve Knob, Part Number: AP6010664, Made by: Whirlpool. Yay - it is the exact part that I broke! I was assisted by an incredibly wonderful woman at your support line. I gave her several different numbers that were on the receipt for my Jenn-Air range, and she told me which one was the Model Number, AND she confirmed that the above Whirlpool part was the one to use for my range. Amazing service - thank you. Received the part in TWO days (by paying a little extra) and popped it right on in 1 second! Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
