Check if other gas appliances are working to be sure the gas meter is on. Answered by Douglas in 4 hours 14 years ago There are two varieties of Hot Surface Controls: "Basic," in which the program waits a designated amount of time before opening the gas valve, and "proven" in which the control monitors the increasing resistance in the hot surface element and thus "proving" the temperature of the igniter. Sensor is the round element part with wires attached to it and the burner flames heat, when burners are on. Hot Surface Igniters: These igniters glow red when voltage flows through them. The gas hits the hot surface ignitor, and whoosh, your furnace is firing up. Once the thermostat signals a need for heat, the furnace ignitor springs into action. The intermittent pilot unit comes with an electric spark that switches on the pilot light. You can check for the 24vac from the control board to the gas valve. I determined the cause was failure of the 10-amp rated, 12 volt, SPST inducer motor relay on the control board. At various times, one burner comes on but the other does not, sometimes both come on at a reduced flame, and it is taking a long time to heat up the oven.

Disconnect the push-on wire connector powering the ignitor. Intermittent pilot: These ignition systems also use electric sparks, but they light the pilot flame as needed instead of the burner. After the ignitor gets hot enough, the sensor calls for the gas valve to open and supply the gas, which ignites the furnace. Do not ignore this problem because it is a serious safety issue. In general, studies by the API on the ignition of hydrocarbons by a hot surface suggest it should not be assumed unless the surface temperature is approximately 182 °C (360 °F) above the minimum ignition temperature of the hydrocarbon involved. The blower runs for a time dissipating the heat in the furnace and then shuts down. This is the lynchpin for the rest of the components to activate, so if you see a glow, it’s normal. It will do this a few time, sometimes burners come on and sometimes not. The igniter will not glow until the pressure switch has proven. Figure 1 is an example of a very simple application of hot surface ignition using silicon carbide igniters. Hot surface ignition sources glow red hot when the thermostat calls for heat.
