Beverlie Y Emmaus , PA October 10, 2021 Appliance: Model 13057400 Washer timer knob broke. This is an old Kenmore (Sears) unit. That knob was made out of plastic. The replacement is made out of metal. It took us seconds to put the new one on! The best part was that we received the replacement knob the very next day!!
