Is the safety valves sensor properly mounted in the pilot?
Electronic Ignition Systems Constant Pilot with Flame Switch (rare) This older type of electronic ignition system was popular in the mid 70’s and is for the most part no longer used but ranges/ovens employing it may still be in service. It was a fairly reliable setup. On this style of ignition system there is a constantly burning pilot similar to the pilot ignition system described above but the pilot flame does not change in size as the control is turned on. This system uses a ‘flame switch’ to detect that the pilot is lit instead of a safety valve like on the pilot ignition system. The thermostat on such a system is just electrical and does not alter gas flow to the oven. The pilot flame should heat the tip of the flame switch’s sensor bulb to a red colour. If the flame switch detects sufficient heat on its sensor bulb at the pilot, it will close an electrical contact in its base. Once the thermostat is turned on, current will be allowed to flow through the flame switch to the oven v
