Lighting a pilot light on a furnace is a common task that many homeowners may need to perform at some point. A pilot light is a small flame that continuously burns to ignite the main gas burner when heat is needed. If the pilot light goes out, the furnace will not be able to produce heat, leaving you without warmth in your home.
There are several reasons why a pilot light may go out, including drafts, power outages, or a faulty thermocouple. Lighting the pilot light is a relatively simple process, but it is important to follow the instructions carefully to avoid any safety hazards.
To light a pilot light on a furnace, you will need a long lighter or match. First, locate the pilot light assembly. This is typically a small metal box with a viewing window located near the bottom of the furnace. Once you have located the pilot light assembly, follow these steps:
- Turn off the gas supply to the furnace.
- Wait five minutes for the gas to dissipate.
- Push in the reset button on the pilot light assembly.
- Hold a long lighter or match to the pilot light opening.
- Turn the gas supply back on.
- Keep the button depressed for 30 seconds after the pilot light ignites.
- Release the button and the pilot light should remain lit.
If you are unable to light the pilot light after following these steps, there may be a more serious problem with your furnace. In this case, it is best to call a qualified HVAC technician for assistance.
1. Safety
Safety is the most important aspect to consider when lighting a pilot light on a furnace. Gas furnaces can be dangerous, so it is important to take all necessary precautions to avoid injury. Make sure to turn off the gas supply to the furnace before you begin, and wait five minutes for the gas to dissipate before attempting to light the pilot light.
- Always follow the manufacturer’s instructions. Each furnace is different, so it is important to follow the specific instructions for your model. The manufacturer’s instructions will tell you how to safely turn off the gas supply, locate the pilot light assembly, and light the pilot light.
- Never attempt to light a pilot light if you smell gas. If you smell gas, it means there is a leak. Turn off the gas supply immediately and call a qualified HVAC technician to repair the leak.
- Keep children and pets away from the furnace. Furnaces can be hot and dangerous, so it is important to keep children and pets away from them.
