If your furnace pilot light is out, it can lead to a chilly home and potentially higher energy bills. The pilot light is a small flame that ignites the burners in your furnace, and when it’s out, your heating system won’t function properly. Here’s a step-by-step guide to help you relight it safely and efficiently.
How to Relight a Furnace Pilot Light?
Relighting a pilot light is a straightforward process, but safety is paramount. Follow these steps:
-
Turn Off the Furnace: Locate the gas valve and turn it to the ‘Off’ position. Wait for at least five minutes to ensure that any residual gas dissipates.
-
Locate the Pilot Light Assembly: This is usually found near the bottom of the furnace, where you’ll see a small knob labeled ‘Pilot.’
-
Switch to ‘Pilot’: Turn the gas valve to ‘Pilot.’ Press and hold the reset button.
-
Ignite the Pilot Light: While holding the reset button, use a long lighter or match to light the pilot. Continue holding the button for 30 seconds to ensure the flame stays lit.
-
Release and Turn On: Release the reset button and turn the gas valve to the ‘On’ position. Your furnace should start operating normally.
Why Did My Furnace Pilot Light Go Out?
Understanding why your pilot light went out can help prevent future issues. Common reasons include:
- Drafts: A strong draft near your furnace can blow out the pilot light.
- Dirty Pilot Orifice: Dust or debris can clog the pilot orifice, preventing it from staying lit.
- Faulty Thermocouple: This safety device shuts off gas if the pilot light goes out, but if it’s malfunctioning, it might cut the gas supply prematurely.
Safety Tips for Relighting a Pilot Light
- Ventilate the Area: Ensure the area around the furnace is well-ventilated before attempting to relight the pilot light.
- Avoid Flammable Materials: Keep flammable materials away from the furnace.
- Consult a Professional: If you’re unsure or uncomfortable, contact a professional HVAC technician.
When to Call a Professional?
If you encounter any of the following issues, it’s best to call a professional:
- Repeated Outages: If the pilot light keeps going out, there might be an underlying issue.
- Gas Smell: A persistent gas smell indicates a leak, which requires immediate professional attention.
- Complex Systems: Modern furnaces might have more complex ignition systems that require expert handling.
