Loved the hot plate so as long as it was just me and my husband, I was all right with the lack of a cook top. When I cleaned up the cook top, I observed that one of the Control nobs has a piece of plastic protruding from the sleeve. Dah! I ordered a brand new set of Control Knobs and Knob Skirts to match and after I placed my order, I checked with Amber to see if the items were compatible with my cook top. Yes, they were ... (Thank you Amber).
I installed the items I ordered with my hands, turned on the gas and plugged in the electric cord and announced to myself, "Bravo old lady." (I will be 85 in November.)
