Broken gas knobs Rachana P. • Belmont, CA • June 20, 2014 My Repair & Advice We ordered gas knobs from ApplianceParts. They came super quick, and we just had to take them out of the packaging and install them. We also talked with them over the phone, and their customer service was superb!! We will definitely visit ApplianceParts before going anywhere else! Fantastic experience! Was this review helpful to you?
