Steve M Boca Raton , FL January 07, 2017 Appliance: Model MODEL NUMBERS ON THE INSIDE OF THE DOOR. Broken control knobs on dryer Ordered the replacement knobs from Appliance Parts Pros and the knobs were the exact match. The repair could not if been easier. Also I noticed the replacements were reinforced to resist cracking around the slot ring connections. Top quality! Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
