Any gas furnace uses a pilot light to trigger the burners to heat your home. The pilot light is a small flame that’s either lit manually and also stays burning around the clock or is attached electronically through an igniter once the machine kicks. Standard maintenance and troubleshooting are part of the maintenance on a chimney to guarantee the pilot light stays functioning.
Debris
The hint of the pilot light in which the gas comes out and ignites is a harbor for collecting soot, grime and grit over recent years. From time to time, this hint can get clogged with debris that blocks the flow of gas, leading to a pilot light that won’t stay lit. As a general rule, a toothbrush or a small, stiff brush is enough to wash the tip. If you would like to be thorough, turn off the gas for your chimney, completely remove the hint and soak it in degreasing solution, such as what is used to remove grime from stovetops. After the debris was removed, the pilot light should remain lit on its own. For best results, wash the pilot light every few months to prevent it from becoming clogged.
Flame Adjustment
Flame adjusters control the size of the pilot light’s flame. If the flame is too small, it won’t kick the burners. Not all furnaces have a fire adjuster. If yours does (refer to your owner’s manual), then it will be a small bolt or a small screw near the pilot light itself. In most cases, there should be a sticker or label near the pilot light that definitely details which direction to turn the screw to adjust the size of the fire. If in doubt, make small adjustments to the screw/bolt and examine the visible size of the fire while the pilot light is lit. Occasionally during routine cleaning, or because of vibration of the unit, this alteration can accidentally be turned down, leading to a flame that’s too tiny.
Supply
Your furnace requires fuel to keep the pilot light engaged along with the burners working. If there’s a leak, if there is no gas in the reservoir or the valve from the reservoir is turned away, gas will not arrive in the pilot light. Check to ensure your tank has lots of fuel, if applicable. Then, check to ensure that all valves along the supply line have been turned on. Finally, check for leaks. A visible smell of petrol is 1 indication, but if you are in doubt, coat any pipe connections with a combination of dish soap and water. If there are leaks, bubbles appear on the surface of the alternative. Leaks need to be repaired immediately to avoid potentially catastrophic outcomes.
Ignition Switch
If your furnace is an electronic prototype with an automatic ignition for the pilot light but it won’t mild, there may be an issue with the ignition. To ascertain this, turn off the thermostat. For best results, turn it off at the breaker box and wait a few minutes to turn everything back on. Occasionally this resets the machine. After you turn the device back on, then listen and watch to see whether the furnace kicks on and the ignition discharges. If your unit has a hot surface igniter, it should start to glow to prepare to ignite the burner. If none of these things occurs while electricity to the furnace is turned on, then there’s an electronic issue that has to be evaluated and repaired by a licensed professional.
