How To Turn On Pilot Light On Gas Furnace

Before you start, remember that gas furnaces can be dangerous. If you aren’t comfortable working on gas appliances, it’s best to call a qualified technician. However, if you’re feeling confident, here’s a step-by-step guide on how to turn on the pilot light of a gas furnace.

Step 1: Safety First

Before you begin, make sure the gas valve to your furnace is turned off. This is usually a small valve located near the bottom of the furnace. Once the gas is turned off, wait a few minutes for any residual gas to dissipate.

Locate the pilot light assembly. This is usually a small metal tube with a flame burning at the end. The pilot light assembly is usually located near the bottom of the furnace, behind a small access panel.

Step 2: Light the Pilot Light

Hold a lighted match or lighter near the pilot light assembly. You may need to use a long match or lighter to reach the pilot light. Once the pilot light is lit, continue to hold the match or lighter in place for about 30 seconds, or until the flame is burning steadily.

If the pilot light does not stay lit, there may be a problem with the thermocouple. The thermocouple is a small device that senses the flame and keeps the gas valve open. If the thermocouple is faulty, it will need to be replaced.

Step 3: Adjust the Pilot Light

Once the pilot light is lit, you can adjust the flame to the correct size. The flame should be about 1 inch high. You can adjust the flame by turning the adjustment screw on the pilot light assembly. Turn the screw clockwise to increase the flame size and counterclockwise to decrease the flame size.

Once the pilot light is adjusted, turn the gas valve back on. You should hear a click as the valve opens. Wait a few minutes for the furnace to start blowing warm air.

Step 4: Turn the Thermostat Up

Once the furnace is blowing warm air, turn the thermostat up to the desired temperature. The furnace will continue to run until the temperature is reached.

Tips and Expert Advice

Here are a few tips and expert advice to help you turn on the pilot light on your gas furnace:

  • If the pilot light does not light after several attempts, there may be a problem with the gas supply. Check to make sure that the gas valve is turned on and that there is no blockage in the gas line.
  • If the pilot light stays lit but the furnace does not blow warm air, there may be a problem with the furnace’s blower motor. The blower motor is responsible for circulating the warm air throughout the house.
  • If you are not comfortable working on gas appliances, it is best to call a qualified technician. A technician can safely and correctly turn on the pilot light and troubleshoot any problems with the furnace.
