Relighting the pilot on your furnace can be a daunting task, especially if you’re not familiar with the process. However, with the right steps and precautions, you can successfully relight the pilot and get your furnace up and running again. In this article, we’ll walk you through the process of relighting the pilot on your furnace, step by step.
What is a Pilot Light?
Before we dive into the relighting process, it’s essential to understand what a pilot light is. A pilot light is a small flame that ignites the main burner of your furnace, providing heat to your home. The pilot light is usually located at the bottom of the furnace and is controlled by a valve that allows gas to flow to the burner.
Why Relight the Pilot?
There are several reasons why you may need to relight the pilot on your furnace. Here are a few common reasons:
- Loss of Power: If your furnace loses power, the pilot light may go out.
- Faulty Thermostat: If your thermostat is faulty, it may not be able to keep the pilot light lit.
- Clogged Gas Line: If your gas line is clogged, it may not be able to supply enough gas to the pilot light.
- Pilot Light Goes Out: Sometimes, the pilot light simply goes out due to normal wear and tear.
How to Relight Pilot on Furnace
Relighting the pilot on your furnace is a relatively simple process, but it does require some caution and attention to detail. Here’s a step-by-step guide to help you relight the pilot:
Step 1: Turn Off the Gas Supply
Before you start the relighting process, you need to turn off the gas supply to your furnace. This is an important safety precaution to prevent any accidental gas leaks. You can usually find the shut-off valve near the furnace or at the gas line.
Step 2: Remove the Access Panel
To access the pilot light, you need to remove the access panel on the front of the furnace. This panel is usually held in place by screws or clips. Once you’ve removed the panel, you’ll see the pilot light assembly.
Step 3: Press the Pilot Light Button
Once you’ve accessed the pilot light assembly, press the pilot light button. This button is usually located near the pilot light and is used to shut off the gas supply to the pilot light.
Step 4: Light the Pilot Light
Use a lighter or match to light the pilot light. You’ll know the pilot light is lit when you see a small flame.
Step 5: Turn the Gas Supply Back On
Once the pilot light is lit, you can turn the gas supply back on. Make sure the shut-off valve is fully open.
Step 6: Check the Pilot Light
Once the gas supply is back on, check the pilot light to make sure it’s still lit. If it’s not, you may need to relight it again.
