Elizabeth E Waterford , PA September 07, 2014 Needed new dryer knob timer I would highly recommend working with Appliance Parts Pros. Customer service was extremely helpful when I had ordered the incorrect knob. The correct knob arrived within 2 days time. A highly efficient and competent company to work with! 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
