How to Turn On Heater Pilot
Heater pilots are essential components of a heating system, responsible for igniting the burner to produce warm air. When the heater pilot is turned off or not functioning correctly, it can lead to a situation where the heating system won’t turn on. This article will provide a comprehensive guide on how to turn on the heater pilot, outlining the steps and precautions you need to take.

**Understanding Heater Pilots
Before diving into the process of turning on the heater pilot, it’s essential to understand its functioning. A heater pilot is a small gas flame that ignites the main burner of a heating system. When the pilot light is out, the burner won’t ignite, and the system won’t produce heat. Some common reasons for a failing pilot light include:
- Dirty or clogged pilot orifice: Lint, dirt, and debris can accumulate in the orifice, blocking the flow of gas and preventing the pilot from igniting.
- Poor gas supply: Insufficient gas pressure or leaks can prevent the pilot from firing.
- Faulty thermocouple: This safety device shuts off the gas supply if the pilot goes out.
**Turning On the Heater Pilot
To turn on the heater pilot, follow these steps:
- Locate the pilot light: Before attempting to relight the pilot, identify its location. It’s usually indicated by a small metal lid or a yellow or amber-colored glass window.
- Turn off the heater: Ensure the heater is turned off to prevent accidents and ensure your safety while working on it.
- Remove the pilot assembly: Take out the small metal lid or remove any other obstructions to gain access to the pilot chamber.
- Clean the pilot orifice: Use a soft brush or a copper wire to clean any debris or lint from the orifice. Avoid using sharp objects that may scratch or damage the orifice.
- Check gas supply: Ensure the gas supply is turned off and that there are no leaks in the pipes. Check the gauge to ensure proper pressure.
- Inspect the thermocouple: Check the thermocouple for damage or corrosion. If you find any damage, consult a professional to replace it.
- Light the pilot: Use a lighter or a match to relight the pilot. Make sure to hold the flame to the pilot hole for at least 30 seconds to allow the pilot to ignite fully.
- Check for leaks: Inspect the pilot chamber for any leaks or gas escape. Smell for any gas with a soapy-soaked cloth.
- Turn on the heater: Once the pilot light is lit and there are no leaks, you can turn on the heater to test it.
What to Do if the Heater Pilot Won’t Turn On
If you’ve tried the above steps and still can’t get the pilot light to turn on, it may indicate a more serious issue with your heater. In this case:
- Check the control board: Faulty circuits or wiring on the control board can prevent the heater from functioning. Consult an electrician or a certified HVAC technician.
- Inspect the igniter: A faulty igniter or spark module can prevent the pilot from igniting.
- Consult a professional: If none of the above steps resolve the issue, it’s recommended to consult a professional HVAC technician to diagnose and repair the issue.
**Safety Precautions**
When working on your heating system, it’s crucial to follow these safety guidelines:
- Shut off the gas supply: Ensure the gas supply is turned off before working on the system.
- Wear protective equipment: Wear safety glasses, gloves, and a mask to protect yourself from injury or exposure to gas fumes.
- Consult a professional: If you’re not comfortable working with gas or electricity, hire a certified technician to repair or maintain your heating system.
Troubleshooting Common Issues
Here is a table outlining common issues and their possible causes:
| Symptom | Possible Cause |
|---|---|
| Pilot light keeps going out | Dirty pilot orifice, poor gas supply, faulty thermocouple |
| Heater doesn’t turn on | Failed igniter, faulty circuit board, blocked airway |
| Gas leaks smell | Cracked or rusted pipes, loose fittings, improper connections |
Conclusion:
Turning on the heater pilot requires a combination of knowledge, caution, and attention to detail. Following the steps outlined in this article will help you safely and effectively relight the pilot light and get your heating system back up and running. Remember to check for common issues and safety precautions to avoid accidents. If you’re unsure about any aspect of the process, consult a professional to ensure your safety and avoid further damage to your heating system.
