Even though summer is in full swing, it’s never too warm to learn about how to light a furnace pilot light. 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. Here at Premier Heating & Air, your trusted Denver furnace repair and replacement, we understand that furnaces have a tendency of not cooperating when you need them the most.

So, how exactly do you light a furnace pilot light? Let’s explain the basic steps for re-lighting the pilot light of a gas furnace.

  1. Locate the instructions label on your 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.
  2. Find the pilot light and its components. Near the bottom of your furnace is a switch that normally says “pilot,” “on” and “off.” Turn this switch to the off position and wait at least 5 minutes to give the gas time to dissipate so that you don’t start 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.”
  3. Re-light the pilot light. 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.
