With some furnace systems, even the slightest breeze can cause the pilot light to go out, leaving a homeowner with no heat when the thermostat is turned up. Luckily, learning how to light a furnace pilot light is a simple matter.
Furnaces have a tendency of not cooperating when you need them most. Of course, if you think about it, this makes sense because winter is the time when furnaces are working the hardest and can show their age, and their wear and tear.
Here, we'll explain the basic steps for re-lighting the pilot light of a gas furnace.
Every furnace should have a label on it that tells you how to light a furnace. Sometimes, however, the printing may be small or the furnace area may be dark. In these cases, the label may be difficult to read. Keeping the following instructions near your furnace or in another safe spot where they can be located easily will make the task much easier.
Near the bottom of your furnace is a switch that normally says "Pilot," "On" and "Off." Find this switch and turn it to the "Off" position. Wait at least five minutes. This is important because it gives the gas time to dissipate, which is necessary to avoid possibly starting a fire. While you are waiting, take note of the location of the reset button, which should be near the dial you just turned to "Off."
Once the gas has had time to dissipate, turn the knob to "Pilot." Then, hold down the "Reset" button and bring the flame of a long lighter close to the pilot light opening. This should light the furnace pilot light. Once you are sure the pilot light is on, release your pressure on the reset button.
Sometimes, seeing a job being done can help if you're doing it for the first time.The video below shows you the step-by-step process for re-lighting a pilot light to help you get started.
Here are some important things to remember about re-lighting your furnace pilot light.
