How to Restart Pilot Light on Furnace?
As the temperature drops, your furnace becomes a vital part of your home’s heating system. But what happens when the pilot light goes out? In this article, we will guide you through the step-by-step process of restarting the pilot light on your furnace.
Understanding the Pilot Light
Before we dive into the process of restarting the pilot light, it’s essential to understand what it is and what it does. The pilot light is a small flame that ignites the burner in your furnace, producing heat. It’s usually located at the bottom of the furnace and is responsible for maintaining a consistent temperature throughout your home.
Identifying the Problem
If your pilot light is out, it can cause significant discomfort and even lead to safety issues. Some common reasons why the pilot light may go out include:
• Faulty Thermocouple: A faulty thermocouple can prevent the pilot light from igniting.
• Blockages: Blockages in the pilot light assembly can prevent the flame from lighting.
• Improper Installation: Improper installation of the pilot light or furnace can lead to premature failure.
Step-by-Step Guide to Restarting the Pilot Light
Restarting the pilot light is a relatively simple process, but it’s crucial to follow the correct steps to ensure your safety. Here’s a step-by-step guide:

Step 1: Turn Off the Gas Supply
**Important Safety Precaution:**
Before attempting to restart the pilot light, make sure to turn off the gas supply to the furnace. This will prevent any accidental ignitions or gas leaks. Find the shut-off valve behind the furnace and turn it clockwise until it stops. Make sure the valve is fully closed before proceeding.
Step 2: Locate the Pilot Light Assembly
**Pilot Light Assembly Location:**
The pilot light assembly is usually located at the bottom of the furnace, near the burner. It may be protected by a metal cover or surrounded by a glass shield. Be careful when removing any covers or shields to avoid damaging them.
Step 3: Remove Any Obstructions
**Removing Obstructions:**
Check the pilot light assembly for any blockages or debris. Use a small brush or cloth to remove any obstructions. Be gentle when cleaning the assembly to avoid damaging any delicate components.
Step 4: Light the Pilot Light
**Lighting the Pilot Light:**
Use a lit match or lighter to ignite the pilot light. Hold the flame to the pilot light assembly until the flame catches. Keep the flame steady and consistent until the pilot light is fully lit.
Step 5: Check for Leak
**Checking for Leaks:**
After lighting the pilot light, check for any gas leaks by holding a lit match or lighter near the assembly. If the flame flickers or goes out, there may be a gas leak. Shut off the gas supply and contact a professional to investigate.
Step 6: Turn On the Furnace
**Turning On the Furnace:**
Once the pilot light is lit and there are no leaks, turn the gas supply back on. Make sure the valve is fully open. Then, turn the furnace switch to the "on" position. Check the thermostat to ensure the furnace is heating correctly.
Tips and Troubleshooting
- Regular Maintenance: Regularly cleaning and maintaining the pilot light assembly can prevent future issues.
- Gas Leak Detection: Installing a gas leak detector can provide peace of mind and prevent accidents.
- Pilot Light Issues: If the pilot light keeps going out, it may indicate a more serious issue. Contact a professional to diagnose and repair any underlying problems.
Common Mistakes to Avoid
- Turning on the furnace without ensuring the pilot light is lit: This can cause the furnace to malfunction or even ignite flammable gases.
- Not checking for gas leaks: Failing to detect gas leaks can lead to serious accidents or injuries.
Conclusion
Restarting the pilot light on your furnace is a relatively simple process, but it requires attention to detail and a few essential steps. By following this guide and being aware of common mistakes, you can ensure your furnace is running safely and efficiently. Remember to regularly maintain your pilot light assembly and furnace to prevent future issues. If you’re unsure or uncomfortable with any part of the process, it’s always best to contact a professional for assistance.
