What is the voltage of a millivolt oven ignitor?
The voltage is very small, measured in millivolts. This is the basis for a millivolt oven ignitor system. All that's needed is a safety valve that will sense this tiny voltage and open the valve if it is present. If the pilot is out, there is no millivoltage and the safety valve will not open. See figure 6-B.
How does a pilot flame work in an oven?
As in the other spark system, the pilot flame provides a path that drains off the spark current, so the ignitor stops sparking while the pilot is lit. As long as the oven thermostat is turned on , the pilot valve switch stays closed, so the pilot valve stays open and the pilot stays lit.
How does a spark ignition work?
Spark ignition systems use a spark module to generate a pulsing, high-voltage spark to ignite the gas. The spark module is an electronic device that produces 2-4 high-voltage electrical pulses per second. These pulses are at very low amperage, measured in milliamps, so the risk of shock is virtually nil. But the voltage is high enough to jump an air gap and ignite gas. The spark ignition module is usually located either under the cooktop or inside the back of the stove. The same module is used for both the surface burner ignition and the oven burner ignition.
Why won't my millivolt burner start?
If the burner in a millivolt system will not start, typically the problem is the gas valve. Occasionally the problem might be the pilot generator or thermostat. The thermostat in these is just a temperature-sensitive on/off switch. To test, turn it on and test for continuity.
What happens if you test a low voltage valve?
If you try to test a low voltage valve by putting high voltage across it, you will burn it out. Do not confuse the oven gas thermostat valve with the safety valve. The oven gas thermostat valve is a valve you set by hand (the oven temperature knob) to control the oven temperature.
What happens if a gas valve does not ignite?
If it does not ignite, you certainly do not want the gas valve to stay open. This would dump raw unburned gas into the oven and create an explosion hazard. To avoid this, designers use a gas safety valve that does not open until ignition is assured.
What is a gas safety valve?
The gas safety valve, on the other hand, simply prevents gas from flowing to the burner until ignition is guaranteed. In systems with an electrical thermostat, the safety valve opens and closes to cycle the burner on and off, but it still will not open if there is no ignition.
