Flora F Carson , CA June 26, 2015 Broken knob made selection of timed drying impossible To fix, a new knob was ordered. The knob was received within a day or ordering (excellent service) and the old was pulled off and the new put on. It works like a charm. I will definitely return as a customer as needed and will refer to family and friends. Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
