How Do I Relight My Pilot Light?

The furnace’s pilot light ignites the burners and starts the heating process. Pilot lights were once standard on all gas furnaces, but newer systems don’t always contain pilot light ignition systems. Instead, some newer furnaces use electronic ignition systems.

If your pilot light goes out, your furnace will not be able to produce heat because its burners will not ignite. Often, homeowners can relight the pilot themselves. Here’s a step-by-step guide on how to relight a gas furnace’s pilot light.

How to Relight a Pilot Light: 5 Steps

1. Find the pilot light assembly and its reset switch.

The furnace’s pilot light is usually positioned at the bottom of the unit by a knob. The knob is typically marked with three settings:

  1. Pilot
  2. On
  3. Off

If you can’t easily find the pilot light and reset switch, look in your furnace’s manual for a diagram that indicates its location. If you can’t find the physical manual, check the manufacturer’s website online.

2. Set the reset switch to off.

Turn the knob to the “Off” setting. You should be able to adjust it easily using your fingers. This stops the flow of gas.

3. Wait a moment.

It’s important to allow a bit of time to pass from turning off the pilot before attempting to relight it. This lets the gas dissipate from the chamber so you don’t ignite excess gas when relighting the pilot light. A minute to two minutes is sufficient.

4. Relight the pilot light.

Turn the knob to “Pilot,” and let gas to flow to the pilot. Light a lighter or match, then push in the reset button. Hold your flame to the pilot light’s opening. Keep the reset switch depressed until the pilot light is burning steadily. Then, release the button.

5. Observe the furnace.

Once the pilot light is relit and you’ve released the reset button, your furnace should fire up automatically. Observe the pilot light for a few moments to ensure it stays lit. Check the surrounding areas for drafts or other air sources that could have extinguished the pilot light initially.

I was impressed with the conversation and quality I experienced when working with Parker's. Josh took the time to listen to our needs and provide multiple solutions. The workers were communicative and did a great job. We can already tell the difference in quality in our new heating and cooling system.

The friendliest and most professional installers I could have asked for.

-Retha W.

Great company to service your HVAC unit. We have been using Parkers since 2003 and will not use another company to service our unit. Thank you Parkers for being the best in the business!

-Selene B.

Parker's had a technician to our house quickly and Jim was able to have our heat up and running in no time. Will definitely call them for any future heating and cooling needs.

-Rachel G.

One of the owners of the company took the time to work with us to ensure that we had the product that worked best for us. Working with this company reminds us of the customer service that was provided before companies started to outsource portions of their operations. Great praise to Parkers for everything that they do...
