Why My Pilot Light Won’t Stay Lit?
The pilot light is a crucial component in many gas-powered appliances, including furnaces, water heaters, and stoves. Its primary function is to light the main burner, ensuring a safe and efficient ignition of the fuel. However, sometimes the pilot light may refuse to stay lit, leaving you wondering why. In this article, we’ll explore the possible reasons behind a pilot light that won’t stay lit and provide solutions to troubleshoot and fix the issue.
Why My Pilot Light Won’t Stay Lit?
Before we dive into the potential causes, let’s first understand the normal operation of a pilot light. A properly functioning pilot light should maintain a consistent flame, usually between 5-10 cubic feet per minute (cfm), and should remain lit even when the main burner is not in use. If your pilot light is not staying lit, it may be due to one or more of the following reasons:
- Dirty or clogged burner: Debris, such as soot or insect nests, can accumulate in the burner and prevent proper airflow, causing the pilot light to extinguish.
- Incorrect pilot flame size: If the pilot flame is too small or too large, it may not be able to maintain the necessary pressure to keep the main burner lit.
- Malfunctioning thermostat: The thermostat is responsible for regulating the temperature in your home. If it’s not functioning correctly, it may not be sending the proper signal to keep the pilot light lit.
- Faulty igniter: The igniter is responsible for igniting the pilot light. If it’s malfunctioning, the pilot light may not be able to stay lit.
Troubleshooting Techniques
To troubleshoot why your pilot light won’t stay lit, follow these steps:
- Check the pilot flame: Ensure the pilot flame is the correct size and properly adjusted. If it’s too small, try cleaning the burner or replacing the pilot assembly.
- Inspect the burner and pilot orifice: Make sure there are no debris or obstructions blocking airflow. Clean the burner and pilot orifice if necessary.
- Verify the thermostat is functioning correctly: Check the thermostat for any signs of malfunction or damage. If it’s faulty, consider replacing it.
- Test the igniter: Attempt to light the pilot light manually using a lighter or matches. If it still won’t stay lit, the igniter may need to be replaced.
- Check for blockages: Ensure there are no blockages in the pilot light tube or anywhere else in the system. Clear any obstructions that may be preventing the pilot light from staying lit.
- Consult your user manual: Refer to your appliance’s user manual for specific troubleshooting instructions unique to your model.
