If you’re here, chances are you are currently encountering issues with your furnace blowing cool air instead of warm air. This most likely means that your furnace’s pilot light has gone out. Now you are stuck in a position where you need to know how to relight your furnace’s pilot light. If this is something you have never done before, do not worry. We understand this may seem like a daunting task! For your convenience, you have your top-trained Lebanon Heating & Cooling professionals by your side to walk you through the step-by-step process of relighting your pilot light.  


  1. Step One: The first order of business is finding the pilot light. Even though it’s out right now, you should be able to find the burner and pilot light opening without too much trouble. Oftentimes, it’s hidden behind a metal door or panel called the burner cover. If this is the case for your specific furnace model, you will first need to take off the burner cover so we can reach the pilot light’s opening. 
  1. Step Two: Before relighting the pilot light again, make sure that you turned off your furnace at the power source first. Usually, furnace power switches are located at the base of the units. 
  1. Step Three: Next, it’s also important to make sure that the gas supply to the furnace is shut off as well. We recommend this for safety reasons. Whenever you a dealing with gas and equipment, safety should always come first. Look around for the gas valve and shut it off accordingly. In addition, you will want to wait for at least five minutes before continuing on with the relighting process.  
  1. Step Four: It would be a great idea over the next five minutes to utilize this time to carefully clean the pilot light and its immediate surroundings. Make sure to remove any debris. It is safe to use a small brush, toothbrush, or even a cotton swab for this step. Once you’re finished, it will be much easier for the flame to reignite and stay alight. 
  1. Step Five: You can also use this time to locate the pilot light assembly. Generally, the pilot light assembly consists of a knob-like switch that says, “pilot, reset, and on/off.” Wording may vary for your particular furnace model but will be along that line. 
  1. Step Six: Once a minimum of five minutes has passed, twist the knob to the “pilot” setting to initiate the pilot relighting process. This temporarily feeds enough gas to the burner to ignite the pilot light. Then press and hold down the “reset” switch while lighting a long-ended match or lighter in your other hand. Slowly bring it closer to the burner; it should catch once the lighter is close enough. Release your grip on the “reset” switch once the pilot flame ignites and stays ablaze.  
  1. Step Seven: Once you have confirmed your pilot light is functioning once again, go ahead and turn the gas supply back on. 
  1. Step Eight: Lastly, replace the burner cover before you leave! 

You did it – you have successfully relit your pilot light! If, after going through this guide step-by-step, you find that the pilot light does successfully ignite but then goes out immediately after releasing the “reset” button, there may be another issue with your system altogether. If this is the case, please give us a call for further assistance!
