In this post, we'll explore common reasons why your pool heater pilot light isn’t staying lit and provide you with practical solutions to get it back in working order.

Common Problems and Potential Solutions
Below are 5 common reasons why your pool heater pilot light won’t stay lit and possible ways to fix it. This information is designed to serve as a starting point for you and your hired heating professional to consider when diagnosing and addressing your specific situation.
1. Dirty Pilot Orifice
- Problem: Over time, dirt and debris can accumulate in the pilot orifice, restricting gas flow and causing the pilot light to extinguish.
- Potential Fix:
- Turn off the gas supply and allow the pool heater to cool down.
- Locate the pilot orifice and use a small brush or compressed air to clean out any debris.
- Reassemble the components and relight the pilot.
- Replacing the pilot orifice is also an option. You can find the right one for your specific model right here at Parts4PoolHeaters.
2. Faulty Thermocouple
- Problem: The thermocouple is a safety device that detects heat from your pool heater’s pilot light. If it’s malfunctioning, it might shut off the gas supply, causing the pilot light to go out.
- Potential Fix:
- Turn off the gas and allow the heater to cool.
- Locate the thermocouple (usually near the pilot light) and check for any visible damage or wear.
- Swap out the thermocouple with a quality replacement from a reputable supplier, such as Parts4PoolHeaters.
- Ensure it is properly connected to both the gas valve and the pilot assembly.
3. Low Gas Pressure
- Problem: Insufficient gas pressure can prevent your pool heater pilot light from staying lit. This issue might be due to a problem with the gas supply line or the regulator.
- Potential Fix:
- Ensure your gas supply is adequate by checking other gas appliances.
- If low gas pressure is suspected, contact your gas provider to inspect and adjust the pressure.
- Inspect the gas regulator and supply line for any signs of damage or leaks.
4. Damaged Pilot Tube
- Problem: If the pilot tube is cracked or damaged, gas may not reach the pilot light consistently.
- Potential Fix:
- Turn off the gas and allow the heater to cool.
- Inspect the pilot tube for any cracks or damage.
- Source the right replacement pilot tube for your model. You can search our inventory by part name or part number.
- Install the new pilot tube and make sure it is securely connected.
5. Ventilation Issues
- Potential Problem: Poor ventilation around the pool heater can cause the pilot light to be extinguished by drafts or lack of oxygen.
- Potential Fix:
- Check the area around the pool heater for any obstructions that might block airflow.
- Ensure there’s adequate ventilation by opening vents or installing additional ventilation if necessary.
- Avoid placing the heater in enclosed spaces where drafts can easily extinguish the pilot light.
