Pool Heater Pilot Light: Troubleshooting and Maintenance
A pilot light is essential to any pool heater system, as it ignites the burners and heats the water. However, if the pilot light goes out, the heater won’t work, and you won’t be able to enjoy your pool. This article will discuss the causes of pilot light problems and provide troubleshooting tips and maintenance recommendations to keep your pool heater running smoothly.
What is a pool heater pilot light?
A pool heater pilot light is a small flame that ignites the gas burner in a pool heater. It is a crucial heating system component and allows the pool heater to function correctly.
Types of Pool Heater Pilot Lights
There are two types of pool heater pilot lights: standing pilot lights and electronic ignition pilot lights.
Standing Pilot Light
A standing pilot light is a small, constantly burning flame that ignites the gas burner when the pool heater is turned on. This type of pilot light has existed for a long time and is still used in many older pool heaters.
Electronic ignition pilot light
On the other hand, an electronic ignition pilot light does not have a constantly burning flame. Instead, it uses an electric spark to ignite the gas burner when the pool heater is turned on. This type of pilot light is more energy-efficient and is used in most newer pool heaters.
How Does a Pool Heater’s Pilot Light Work?
Standing Pilot Light Operation
When the pool heater is turned on, the gas valve opens and releases gas to the pilot light. The standing pilot light ignites the gas, which travels to the main burner and heats the pool water. When the pool heater is turned off, the gas valve closes, and the pilot light goes out.
Electronic Ignition Pilot Light Operation
When the pool heater is turned on, an electric signal is sent to the electronic ignition system. The system then creates a spark that ignites the gas burner. Once the gas burner is lit, the pool water is heated. When the pool heater is turned off, the electronic ignition system stops sending the electric signal, and the gas burner goes out.
Common Problems with Pool Heater Pilot Lights
Both types of pool heater pilot lights can experience problems over time. Here are some common issues:
Standing Pilot Light Issues
- The pilot light won’t stay lit.
- The pilot light is too weak or too strong.
- The pilot light keeps going out.
- The thermocouple needs replacing.
Electronic Ignition Pilot Light Issues
- The ignition system won’t spark.
- The ignition system sparks but doesn’t light the burner.
- The ignition system sparks intermittently.
- The flame sensor needs to be replaced.
How to Troubleshoot Pool Heater Pilot Light Issues
Standing Pilot Light Troubleshooting
- Check the gas supply.
- Clean the pilot light orifice.
- Replace the thermocouple.
- Adjust the pilot light flame.
Electronic Ignition Pilot Light Troubleshooting
- Check the power supply.
- Clean the ignition electrode.
- Replace the flame sensor.
- Adjust the gas pressure.
Maintenance of pool heater pilot lights
Regular maintenance is required to ensure your pool heater’s pilot light functions appropriately. This includes:
- Cleaning the pilot light orifice and gas burners
- Checking the gas pressure and adjusting it if necessary.
- Replacing worn-out parts such as thermocouples, flame sensors, and ignition electrodes
Advantages of Using a Pool Heater Pilot Light
Pool heater pilot lights are essential for the proper functioning of pool heaters. Some advantages of using a pool heater pilot light include the following:
- Efficient heating: Pool heater pilot lights provide consistent and efficient heating for your pool, ensuring the water is always at the desired temperature.
- Cost-effective: Electronic ignition pilot lights are more energy-efficient than standing pilot lights, which can help you save money on your energy bills.
- Easy to maintain: Regular pool heater pilot light maintenance can help prevent issues and ensure that it functions properly.
- Reliable: When properly maintained, pool heater pilot lights are reliable and can last many years.
Understanding the Basics of a Pool Heater Pilot Light
As the summer approaches, many homeowners are preparing their swimming pools for a season of fun in the sun. One crucial aspect of pool maintenance is ensuring the pool heater is in good working order. One common issue with pool heaters is the pilot light. This article will explore the basics of the pool heater pilot light, how it works, and what to do when it’s not working correctly.
Introduction to the Pool Heater Pilot Light
A pool heater pilot light is a small flame that ignites the gas burner in the pool heater. It is the first step in the process of heating the pool water. Without a working pilot light, the pool heater will not function correctly.
How Does a Pool Heater Pilot Light Work?
The pool heater’s pilot light uses a small flame to ignite the gas that fuels the burner. The gas valve in the pool heater is connected to a thermocouple, a device that senses the heat from the pilot light. If the pilot light burns correctly, it will produce enough heat to keep the thermocouple warm, and the gas valve will remain open. This allows gas to flow to the burner, and the pool heater will start heating the pool water.
Common Issues with the Pool Heater Pilot Light
Pool heater pilot lights can experience several issues that may cause them to stop working correctly. Some of the most common problems with pilot lights include:
Clogged Pilot Tubing or Orifice
Over time, the pilot tubing orifice can become clogged with debris or spider webs. This can prevent gas from flowing correctly, which will cause the pilot light to go out.
If the thermocouple is faulty, it will not correctly sense the pilot light’s heat. This will cause the gas valve to close, and the pool heater will stop working.
Low gas pressure
If there is low gas pressure in the pool heater, it may cause the pilot light to go out. This can happen if the gas supply line is too small or there is a gas regulator problem.
Wind or draughts
Strong winds or draughts can blow out the pilot light. If this happens, the pool heater will not function correctly.
How to Troubleshoot Pool Heater Pilot Light Issues?
If your pool heater’s pilot light is not working correctly, there are a few steps you can take to troubleshoot the issue. Here are some tips:
Check for obstructions
Inspect the pilot tubing or orifice for any obstructions blocking the gas flow.
Check the thermocouple
The thermocouple may be faulty if the pilot light is burning correctly but the gas valve is not opening. Check the thermocouple with a multimeter to see if it’s working perfectly.
Check the gas pressure
Make sure that the gas pressure in the pool heater is sufficient. You may need to contact a professional to check the gas line and regulator.
Check for wind or draughts
If strong winds or draughts are in your pool area, block them or shield the pool heater from the wind.
A pool heater pilot light is an essential component of a pool heater system, and it is crucial to keep it functioning correctly. By following the troubleshooting tips and maintenance recommendations in this article, you can ensure that your pool heater’s pilot light is in good condition and that your pool is always warm and ready for use.

Can I replace the pilot light myself?
It is possible to replace the pilot light yourself, but following the manufacturer’s instructions and ensuring you have the necessary skills and tools to do the job safely is essential.
How often should I inspect and clean my pool heater pilot light?
You should inspect and clean your pool heater pilot light at least once a year, or more often if you use your pool frequently.
Why won’t my pilot light stay lit?
A pilot light that won’t stay lit may be caused by a dirty or clogged pilot light orifice, a faulty thermocouple, or low gas pressure or supply.
How do I know if my thermocouple is faulty?
The thermocouple may be faulty if the pilot light won’t stay lit or the burners won’t ignite. You can test the thermocouple with a multimeter to check for continuity.
How do I clean the pilot light orifice?
Turn off the gas supply and use a wire brush or compressed air to remove debris or blockages from the pilot light orifice.
