Pilot light is on, but oven will not get hot. When I light with a lighter the pilot light will not enlarge or spread.
Answer Jones, Yes, the safety valve WB19K12 is the next logical and most likely issue. The heat from the pilot is transferred to the safety valve and opens the valve for ignition and burner flame. This is a milliamp / millivolt system and does not take a lot to become waeak and fail.
