The numbers had worn off

I didn't have a part number or a model number, so I went on line and googled 'General Electric thermostat knob', and the first selection was PartSelect. It was easy, fast and most of all, a lot less expensive than I had found at the local hardware stores, even after shipping. The part was exactly what I needed. PartSelect's site is very user friendly and easy to get through. From now on, I'll go to PartSelect for any parts I need for my appliances.
