Having a pool heater is a great way to extend your swimming season and enjoy a warm pool even when the weather is cool. However, like any other appliance, pool heaters can sometimes experience faults and breakdowns. In this article, we will discuss some common ignition-related issues that pool heaters may encounter and the steps you can take to troubleshoot and resolve them.

Ignition Failure

One of the most common issues with pool heaters is ignition failure. This can happen due to various reasons, such as a clogged burner, a malfunctioning ignition switch, or a faulty gas valve. When the ignition fails, the heater will not be able to heat the pool water, leaving you with a cold swimming experience.

Step 1: Check the Gas Supply

The first step in troubleshooting an ignition failure is to check the gas supply. Make sure that the gas valve is turned on and that there is an adequate supply of gas. You can do this by checking the gas meter or contacting your gas provider to ensure that there are no gas outages or interruptions in your area.

Step 2: Inspect the Burner

If the gas supply is not the issue, the next step is to inspect the burner. Remove the cover of the heater and visually inspect the burner for any signs of clogs or blockages. Use a brush or compressed air to clean out any debris that may be obstructing the burner. Make sure to follow the manufacturer’s instructions when cleaning the burner to avoid any damage.

Step 3: Check the Ignition Switch

If the burner is clean and free of obstructions, the next step is to check the ignition switch. The ignition switch is responsible for initiating the ignition sequence and lighting the burner. Inspect the ignition switch for any signs of damage or wear. If necessary, replace the ignition switch with a new one to ensure proper ignition.

Step 4: Test the Gas Valve

If the ignition switch is functioning properly, the issue may lie with the gas valve. The gas valve controls the flow of gas to the burner. Use a multimeter to test the continuity of the gas valve. If the multimeter reading shows no continuity, it means that the gas valve is faulty and needs to be replaced.


Pool heater ignition failure can be a frustrating problem, especially when you’re looking forward to enjoying a warm swim. By following these troubleshooting steps, you can identify and resolve common ignition-related issues with your pool heater. However, if you’re unsure or uncomfortable with performing these steps, it’s always best to consult a professional pool heater technician for assistance.
