Or, perhaps the spark happens but does not light the pilot. In this case, you need to wait until the cooktop cools down, and the light will go off immediately. Hey everyone. Most furnaces use an igniter and flame sensor to ignite the gas and supply heat to the home. Both systems are designed to be energy-efficient. This means if the cooktop is hot, the temperature light will stay on, preventing users from accidentally burning themselves or getting hurt in the process.. Some of these conditions are dangerous. Usually, electric cooktops have built-in heat sensors that are designed to keep the unit safe. I have a rheem 90 plus furnace and the ignitor stays lit but the main burners will not ignite,the blower stays on and ... Is this spark ignition (lights a pilot and then main burners) or hot surface (a glow plug lights the burners)? LifeTime Supporter. The ignitor turns off about 3 seconds after the gas valve opens and times out after 3 attempts to light (goes into lockout mode).There are led monitors on the control module and the flame sensor stays off also, confirming there is no combustion. I installed a new igniter which solved my problem but I would like to know if the igniter should stay on while the oven is heating, it is 5 years old and I never paid any attention to the working of it, you know how it is, get a range, hook it up and use never paying attention to how it runs until you have a problem. The hot surface ignition type, however, uses electrical power to heat up the area. The majority of gas furnaces, both natural gas and propane, are fired by an ignitor rather than a pilot light.The ignitor (or igniter) is typically a hot surface ignitor (HSI). It is also referred to as a glow plug or glow bar because electric resistance causes the ignitor to glow red-hot, about 1200 F, to ignite combustion. As the igniter draws electric current it will heat to a high temperature and glow, as well as cause the bi metal in the oven safety valve to warp and open the valve releasing the gas to be ignited. You indicated that the light finally turned off when you lifted that top. It works like a light bulb filament, heating up when electricity is passed through it.
