Peter N Tucker , GA March 19, 2018 Old age Thanks to the excellent service provided by Edward, who researched the proper parts for my old electric stove top, I replaced the heating elements, drip pans, and knobs. It took five minutes, was easy, and the stove top looks and works great. This project started because a knob broke and I was looking for a replacement. I decided to replace everything once I had confidence I was getting the right parts. I originally purchased knobs on Amazon that did not fit. The Whirlpool site identified my model as having been discontinued but provided no guidance on part numbers for current replacement parts. The service provided by Edward was great, and the prices were lower than buying directly from Whirlpool. Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
