Common Reasons Your Pilot Light Won't Stay Lit
There are a handful of common issues that are usually at the root of your pool heater pilot light’s inability to remain lit. We’ve compiled these problems, as well as potential fixes, into the convenient list below. This guide is intended to help you and your heating specialist diagnose and resolve the problem.
Thermocouple Issues
- Problem: The thermocouple is a safety device that detects whether the pilot light is on. If the thermocouple is faulty or dirty, it may not correctly sense the pilot light, causing it to go out. This can be due to wear and tear or dirt accumulation.
- Potential Solution: First, ensure the thermocouple is clean and free of debris. You can clean it using fine sandpaper or a brush. If the thermocouple appears damaged or worn out, it may need to be replaced. At Parts4HeatingSystems, we carry a wide variety of high-quality thermocouples that are compatible with various heating systems.
Dirty Pilot Orifice
- Problem: Over time, dirt and debris can clog the pilot orifice, restricting the gas flow to the pilot light. This can result in a weak flame or cause the pilot light to go out altogether.
- Potential Solution: Turn off the gas supply before attempting to clean the pilot orifice. Use a thin wire or needle to gently clear any blockages. Make sure the area is clean and reassemble the components carefully. If necessary, you can also replace the pilot orifice with a quality spare from a reputable provider, such as Parts4HeatingSystems.
Drafts or Strong Airflow
- Problem: Strong drafts or airflow can blow out the pilot light. This is especially common in older homes with poor insulation or in systems that are located near windows or vents.
- Potential Solution: Inspect the area around your heating system for drafts. Seal any gaps or cracks near windows, doors and vents that might allow cold air to blow out the pilot light. Adding weather stripping or insulation can help mitigate this issue as well.
Faulty Gas Valve
- Problem: The gas valve controls the flow of gas to the pilot light and the burner. If the valve is malfunctioning, it may cut off the gas supply, extinguishing the pilot light.
- Potential Solution: If you suspect a faulty gas valve, it's essential to have a professional technician test it for proper operation. If the valve is indeed faulty, replacing it with a new one from Parts4HeatingSystems can restore your heating system's functionality.
Low Gas Pressure
- Problem: Insufficient gas pressure can prevent the pilot light from staying lit. This can be due to issues with the gas supply or problems within the heating system itself.
- Potential Solution: Check the gas pressure to ensure it meets the manufacturer's specifications. This requires assistance from your gas provider or a qualified technician. Ensuring adequate gas pressure can help maintain a consistent pilot light.
