David G Hindman , KY May 23, 2020 Appliance: Model ? Two missing knobs and one broken switch. I received the parts which were a perfect match. I turned the power off removed the burners lifted the top and replaced the switch. I checked for correct operation.Reinstalled the top and put the new knobs on. The homeowners were tickled to death.
