Inspection required Does the oven gas valves terminals show continuity?
Hot Surface (‘Glow Bar’) Ignition System Glow (most common) This is the most popular system currently in use and is comprised of a control mechanism (whether thermostat or electronic control), the oven ignitor and an oven gas valve. What happens in this style control system is that the thermostat or electronic control supplies power to the oven ignitor and gas valve which are connected in series (one after the other). As power flows through the ignitor it heats and allows a specific amount of current to flow to the oven valve which is in the same circuit. If the oven valve senses the proper current flow, it opens to allow gas to flow to the oven burner where the glowing hot ignitor (glow bar) ignites it. Example gas oven ‘hot surface’ ignition system circuit It should usually only take in the area of 30-90 seconds for the oven ignitor to reach the proper resistance to allow the gas valve to open and for the ignitor to ignite the oven burner. Example gas oven valves – single and dual Ma
