GAS OVEN BURNER IGNITION

If the unit is a gas unit and is giving an F9, F19 the main needs to see approximately 3.3 Amps before it will open the gas valve. The range of resistance for the igniter is approximately 45 ~ 400Ω,  3.1 ~ 3.3 amps.

Gas Valve: 1 ~ 3Ω

The valve is in series with the ignitor (glow bar).

When 120 VAC is applied, the ignitor requires a minimum of 116, leaving only about 4 volts to operate the valve.

The ignitor will remain energized at all times the burner is operating.

As Ignitor Heats – Resistance Decreases

116 VAC minimum & 3.3 amps
