Is your home feeling chilly even though your thermostat is set to “heat”? You might be dealing with an extinguished pilot light. Don’t worry – relighting a furnace pilot light is often a simple task that many homeowners can handle themselves.
At HVAC Precision Experts, we’re here to guide you through the process step by step. With over 15 years of experience serving Haymarket, we know a thing or two about keeping Virginia homes warm and cozy.
Understanding Your Furnace Pilot Light
Before we walk you through the steps of relighting your furnace pilot light, it’s crucial to understand some basics. This knowledge will not only help you relight the pilot safely but also recognize when it’s time to call in our NATE-certified technicians.
Let’s start by covering some essential information about pilot lights:
What is a Pilot Light?
A pilot light is a small, continuously burning flame that ignites the gas in your furnace when it needs to produce heat. It’s a crucial component in older gas furnaces.
Why Do Pilot Lights Go Out?
There are several reason why a pilot light might extinguish:
Strong drafts of air: Sometimes, a gust of wind from an open window or door can blow out the flame.
A dirty pilot orifice: Over time, dust and debris can clog the tiny hole where the gas comes out, affecting the flame.
A faulty thermocouple: This safety device can wear out, cutting off the gas supply to the pilot light.
Problems with the gas supply: Inconsistent gas flow can cause the pilot light to flicker and go out.
Understanding these causes can help you prevent future issues and know when it’s time for a professional inspection.
How to Tell if Your Pilot Light is Out
You might have an extinguished pilot light if:
- Your house isn’t warming up, even when the thermostat is set correctly
- The furnace won’t turn on at all
- You can’t see the small blue flame when you look at your furnace
If you notice any of these signs, it’s time to check your pilot light. But before you do, let’s talk about safety.
Safety First: When to Call a Professional
While relighting a pilot light is often straightforward, there are situations where it’s best to call in the experts:
If you smell gas: This is crucial. If you detect the rotten egg smell of natural gas, leave your home immediately and call the gas company. Don’t attempt to relight the pilot light yourself.
If you’ve tried to relight the pilot light several times without success: This could indicate a more serious problem with your furnace.
If you’re not comfortable working with gas appliances: There’s no shame in calling for help. Your safety is more important than saving a service call fee.
At HVAC Precision Experts, we’re always here to help if you’re unsure or uneasy about the process. Your safety is our top concern, and we’d rather you call us than take any risks with your home heating system.
Now that we’ve covered the basics, let’s move on to the step-by-step process of relighting your furnace pilot light. Remember, if at any point you feel uncomfortable or unsure, don’t hesitate to reach out to our team.
Preparing to Relight Your Pilot Light
Before you begin, gather these items:
- Flashlight
- Long lighter or fireplace matches
- Your furnace’s instruction manual (if available)
Now, let’s walk through the steps to relight your furnace pilot light:
Step 1: Locate the Pilot Light
First, you need to find the pilot light assembly. In most furnaces, it’s near the bottom of the unit. Look for a small valve or knob labeled “Pilot,” “On,” and “Off.”
Step 2: Turn Off the Gas
Safety is crucial when working with gas appliances. Turn the gas valve to the “Off” position and wait at least 5 minutes. This allows any accumulated gas to dissipate.
Step 3: Access the Pilot Light
Remove the access panel to expose the pilot light assembly. You might need a screwdriver for this step.
Step 4: Prepare to Light
Turn the valve to the “Pilot” setting. This allows gas to flow to the pilot light.
Step 5: Light the Pilot
Here’s where you’ll need steady hands:
1. Press and hold down the reset button (usually red) near the pilot light valve
2. While holding the button, use your long lighter or match to ignite the pilot light
3. Continue holding the reset button for about a minute after the flame ignites
Step 6: Restore Gas Flow
Once the pilot light is burning steadily, slowly release the reset button. If the flame stays lit, turn the valve from “Pilot” to “On.”
Step 7: Test Your Furnace
Replace the access panel and turn your thermostat to “Heat.” Set the temperature a few degrees above the current room temperature. Your furnace should kick on within a few minutes.
Congratulations! You’ve successfully relit your furnace pilot light. If your furnace doesn’t start or the pilot light goes out again, it’s time to call in the professionals at HVAC Precision Experts.
Troubleshooting Common Pilot Light Issues
Even after following these steps, you might encounter some issues. Here are some common problems and their solutions:
1. Pilot Light Won’t Stay Lit
If the pilot light goes out as soon as you release the reset button, you might have a faulty thermocouple. This safety device shuts off the gas if the pilot light goes out. A bent or dirty thermocouple can cause it to malfunction.
Solution: Try cleaning the thermocouple with fine-grit sandpaper. If this doesn’t work, you may need to replace it. This is a job best left to professionals.
2. Pilot Light is Yellow or Orange
A healthy pilot light should burn blue. If it’s yellow or orange, it indicates incomplete combustion, which can lead to carbon monoxide production.
Solution: This often indicates a dirty pilot orifice. Turn off the gas and carefully clean the orifice with a thin wire. If the problem persists, call HVAC Precision Experts for a thorough cleaning and inspection.
3. Pilot Light is Too Large or Small
An improperly sized pilot light can cause inefficiency or frequent outages.
Solution: The pilot light flame should be about 3/4 inch to 1 inch in height. If it’s significantly larger or smaller, you may need to adjust the pilot light screw. This is a delicate process best handled by a professional.
Preventing Future Pilot Light Problems
While knowing how to relight your pilot light is valuable, preventing it from going out in the first place is even better. Here are some tips to keep your furnace running smoothly:
1. Schedule Regular Maintenance: Annual tune-ups from HVAC Precision Experts can catch and fix minor issues before they become major problems.
2. Keep Your Furnace Clean: Dust and debris can interfere with your pilot light. Keep the area around your furnace clean and uncluttered.
3. Check for Drafts: Strong air currents can blow out your pilot light. Ensure your furnace area is free from drafts.
4. Monitor Your Gas Supply: If your pilot light frequently goes out, there might be an issue with your gas supply. Contact your gas company to check for any problems.
5. Consider Upgrading: If you have an older furnace with a standing pilot light, consider upgrading to a more efficient model with electronic ignition. These systems are more reliable and energy-efficient.
