How to Relight Pilot Light on Furnace: A Step-by-Step Guide
Contents
Introduction
Relighting the pilot light on your furnace can be a daunting task, especially if you’re not familiar with the process. However, with the right guidance, you can easily relight the pilot light and get your furnace up and running again. In this article, we’ll provide a step-by-step guide on how to relight the pilot light on your furnace.
Why is the Pilot Light Important?
The pilot light is an essential component of your furnace, as it provides the necessary ignition source for the burner to ignite the fuel. Without a pilot light, your furnace will not be able to produce heat. Additionally, a faulty pilot light can cause safety issues, such as carbon monoxide poisoning.
Common Reasons for a Pilot Light to Go Out
Before we dive into the relighting process, it’s essential to understand the common reasons why the pilot light may go out. Some of the most common reasons include:
- Dirty or clogged pilot light orifice: Dirt, dust, and debris can accumulate in the pilot light orifice, preventing the pilot light from igniting.
- Faulty thermocouple: The thermocouple is responsible for sensing the pilot light flame and shutting off the gas supply when the flame is extinguished. A faulty thermocouple can prevent the pilot light from igniting.
- Incorrect pilot light adjustment: If the pilot light is not adjusted correctly, it may not be able to maintain a steady flame.
- Low gas pressure: Low gas pressure can prevent the pilot light from igniting.
Relighting the Pilot Light: A Step-by-Step Guide
Relighting the pilot light on your furnace is a relatively simple process. Here’s a step-by-step guide to help you get started:
Step 1: Turn Off the Power
Before you start relighting the pilot light, make sure to turn off the power to the furnace at the circuit breaker or fuse box. This will prevent any accidental ignition of the furnace.
Step 2: Locate the Pilot Light
Locate the pilot light on your furnace. It’s usually located near the burner assembly and is marked with a pilot light symbol.
Step 3: Remove the Pilot Light Cap
Remove the pilot light cap by twisting it counterclockwise. This will give you access to the pilot light orifice.
Step 4: Clean the Pilot Light Orifice
Use a small brush or a toothbrush to clean out any dirt, dust, or debris that may be accumulated in the pilot light orifice. Make sure to wear gloves and work in a well-ventilated area.
Step 5: Replace the Pilot Light Cap
Replace the pilot light cap by twisting it clockwise. Make sure it’s securely tightened.
Step 6: Light the Pilot Light
Use a lighter or matches to light the pilot light. Hold the flame to the pilot light orifice for about 30 seconds to ensure it ignites.
Step 7: Check the Pilot Light
Once the pilot light is lit, check to see if it’s burning steadily. If it’s not, you may need to adjust the pilot light orifice or replace the thermocouple.
Step 8: Turn On the Power
Once the pilot light is lit and burning steadily, you can turn on the power to the furnace at the circuit breaker or fuse box.
Additional Tips and Precautions
Here are some additional tips and precautions to keep in mind when relighting the pilot light on your furnace:
- Make sure to follow the manufacturer’s instructions for relighting the pilot light on your specific furnace model.
- Wear gloves and work in a well-ventilated area to avoid inhaling any fumes or debris.
- Be careful not to touch any hot surfaces while working on the pilot light.
- If you’re not comfortable relighting the pilot light yourself, it’s recommended to hire a professional HVAC technician to do the job.
Conclusion
Relighting the pilot light on your furnace is a relatively simple process that can be completed with the right guidance. By following the step-by-step guide outlined in this article, you should be able to relight the pilot light and get your furnace up and running again. Remember to always follow safety precautions and manufacturer’s instructions to ensure a successful and safe relighting process.
