I have a old Kenmore range and I am looking for a burner valve. Part #7253 which is the burner control valve. The part was manufactored by Frigidaire but has been discontinued. Does anyone have one a shelf or in an old stove? The stove was purchased in 73 and came with the house. It is a gas, four burner stove or range, Kenmore brand, other model numbers are 119.7457310 or same number but ending in 320 or 340 or 360 which are just different colors of the same stove. I know it's a long shot, but I just have to try.
