Not long after purchasing our Samsung range, one of the knobs broke. After trying unsuccessfully to get a replacement from Samsung, I gave up. After a couple of years, I ran across AppliancePartsPros.com, and found just what I needed. The parts were inexpensive, so I replaced all the knobs. It was an easy transaction, and the parts arrived within just a couple of days. Thanks AppliancePartsPros for making an easy job easier.
