How Do I Re-Light A Pilot Light?

Natural gas is ignited by the pilot light in the main burner. During furnace operation, gas is discharged through a valve. The pilot light ignites when gas comes into contact with it.

The pilot light is also powered by natural gas, which comes from a tube in your gas line. A safety valve shuts the gas flow if the pilot light goes out. It prevents gas from accumulating in your furnace and poses a safety hazard.

Bringing A Pilot Light Back To Life

Collect and Arrange the Necessary Tools and Materials

You will need a flashlight and a long-reach lighter or long-handled match to relight your pilot light. If you do not have suitable objects, you can use a tightly curled piece of paper instead. You can also contact professionals for HVAC repair in Arlington, TX.

Check the Guidelines Provided By The Manufacturer.

In most cases, furnaces have a conspicuous label that explains how to relight the pilot light. If you are still looking for a label on the heating system, look for pertinent information in the unit’s manual or the company’s website. A professional for heating repair in Arlington, TX, will be happy to assist you.

Find The Pilot Light For The Furnace

If you’ve read the unit’s instructions or encountered similar issues, you probably know where the pilot light is. Look for a switch with three parameters on the bottom of the furnace: pilot, on, and off.

Allow The Gas To Escape.

When you locate the switch or knob, turn it to the off position. It seals the valve and prevents gas from escaping. After the knob is turned off, any excess gas will disappear. Please wait at least five minutes after turning off the pilot light before turning it back on to prevent starting the fire or injuring yourself. After that, set it to pilot.

Switch On The Pilot Light Again

Light a match, then press the reset button to allow gas to flow to the pilot. Keep your flame close to the pilot light’s entrance. When the pilot light is steady, keep pressing the reset button. Hold the control for a moment, then release it.

Keep An Eye On The Furnace

After you relight the pilot light and remove the reset button, your furnace should start automatically. Check the surrounding area for drafts or other air sources that may have caused the pilot light to go out.

A broken thermocouple is often the cause of pilot light problems. The obstruction of a pilot tube is an indication that there is a blockage. A technician can replace thermocouples, but we recommend enlisting their assistance.


In most contemporary gas appliances, electric starters replace pilot lights, so it is helpful to understand how to relight a pilot light if it goes out on older devices. For example, relight the pilot light on a gas furnace, water heater, oven, or stove by reading up about it.
