If you’re unsure about how to turn off your Jandy pool heater or disconnect the power source, consult the owner’s manual or contact a professional for assistance.

Locate the Power Switch

1. Find the circuit breaker box near your pool equipment. It may be located on the side of your house or in a separate enclosure.

2. Open the circuit breaker box and locate the switch that controls power to your pool heater. It may be labeled or you may need to refer to your owner’s manual for assistance.

3. Switch the breaker to the off position. This will shut off power to your Jandy pool heater and ensure your safety while performing maintenance.

4. Double-check that the power is off by trying to turn on the heater. If it does not turn on, you can be sure that the power is off and it is safe to proceed with the reset.

By turning off the power to your Jandy pool heater, you have taken the first step in resetting your heater’s control board. Now it’s time to move on to the next step.

Turn Off the Power Switch

After locating the power switch, turn it off. Make sure to wait at least five minutes to allow the heater to cool down before continuing with the reset process. This is an important safety measure to avoid any accidents or injuries.

Turning off the power switch will shut off the power to the pool heater, ensuring that it is safe to proceed with the reset process. Double-check that the power is off before continuing.

• It’s important to note that turning off the power switch alone is not enough to reset the heater. You must also reset the control board, which is covered in the next section.
• It’s a good idea to place a sign on the pool heater or near the power switch indicating that maintenance is being performed, so no one accidentally turns the power back on while you’re working on it.
• If you’re unsure about how to turn off the power switch, consult the owner’s manual or contact a professional for assistance.

Common Reasons Your Jandy Pool Heater Needs to be Reset

If your Jandy pool heater is experiencing problems, you may need to reset it. Some common reasons why your heater may need to be reset include:

Power surges: Electrical surges can cause your heater to malfunction and require a reset to restore its normal operation.

Low water flow: Insufficient water flow can cause your heater to overheat and trigger a reset. Check your pool pump and filter to ensure they are working properly.

Dirty filter: A dirty filter can restrict water flow and cause your heater to overheat, leading to a reset. Be sure to clean or replace your filter regularly.

Thermostat malfunction: If your thermostat is not working correctly, it can cause your heater to operate improperly and require a reset. Consider having a professional inspect and repair your thermostat.

Power Surges or Electrical Issues

One of the most common reasons your Jandy pool heater may need to be reset is due to power surges or electrical issues. When there are electrical issues, the heater may not start, or it may display error codes, indicating a problem with the electrical connections.

To prevent power surges, it’s recommended to install a surge protector or a whole-house surge protector to safeguard your pool heater and other electrical appliances. Additionally, make sure to check the electrical connections regularly and fix any loose or corroded wires that could cause issues.

Troubleshooting Tips for Your Jandy Pool Heater

If you are experiencing issues with your Jandy pool heater, there are several troubleshooting steps you can take to identify and address the problem.

Clean or Replace the Filter: A dirty or clogged filter can cause reduced water flow and put extra strain on the heater. Check and clean your filter regularly, or replace it if necessary.

Check the Thermostat: If your heater is not producing enough heat, the thermostat may be set too low. Make sure the thermostat is set to the desired temperature and is working properly.

Inspect the Gas Supply: If your heater is not igniting, there may be a problem with the gas supply. Check to make sure the gas valve is open and the gas line is not kinked or damaged.

Inspect the Igniter: If your heater is not igniting, the igniter may be faulty. Inspect the igniter for damage or wear and tear, and replace it if necessary.

Clean the Filter Regularly

One of the most important things you can do to keep your Jandy pool heater functioning properly is to clean the filter regularly. A dirty or clogged filter can reduce water flow and cause the heater to overheat. Depending on the type of filter you have, you may need to clean it every few weeks or every few months. Check your owner’s manual for specific instructions.

To clean the filter, first turn off the power to the heater and shut off the water supply. Remove the filter from its housing and use a garden hose to spray it clean. You may also need to use a filter cleaner or degreaser to remove stubborn debris. Allow the filter to dry completely before replacing it.

If you have trouble cleaning the filter yourself, consider hiring a professional pool service to perform regular maintenance on your heater and filter. They can ensure that your system is working at peak efficiency and catch any potential problems before they become serious.

Check for Gas and Water Leaks

Leaks can be dangerous and can lead to serious problems if not addressed immediately. Regularly check for any water or gas leaks around your pool heater. Look for puddles of water or the smell of gas near the heater. If you suspect there is a leak, turn off the gas supply and call a professional immediately.

Inspect the gas and water lines regularly for signs of wear or damage. If you notice any cracks, holes, or signs of corrosion, replace the damaged parts immediately. Tighten any loose fittings and connections to prevent leaks from occurring.

Maintain the proper water chemistry in your pool to prevent corrosion of the pool heater and plumbing components. High levels of acidity or alkalinity can cause damage and increase the risk of leaks. Regularly test and balance the water chemistry to ensure proper pH, alkalinity, and calcium hardness levels.

Ensure Proper Ventilation Around the Heater

Ventilation is critical for your Jandy pool heater’s performance and longevity. Proper ventilation ensures that the heater operates at the right temperature, and prevents overheating, which could lead to a fire. Make sure that the heater has enough space around it for ventilation, as specified in the installation manual.

Clean the surrounding area around the heater to prevent dust, debris, or other objects from obstructing the vents. Any restriction of the airflow can affect the heater’s performance and could lead to the formation of soot, which can cause malfunctioning and carbon monoxide poisoning.

Inspect the chimney or vent stack and ensure that it is clean, unobstructed, and free from bird nests or other debris. If you notice any blockages or obstructions, clear them immediately to avoid overheating and the risk of fire.

When to Call a Professional

If you have tried all the troubleshooting tips and your Jandy pool heater is still not working, it may be time to call in a professional.

Additionally, if you smell gas near the heater, hear unusual sounds coming from the unit, or notice water pooling around the base of the heater, it is important to contact a licensed technician immediately.

Another reason to call in a professional is if your Jandy pool heater requires complex repairs that you are not comfortable performing on your own.

If your Jandy pool heater is under warranty, it is important to have any repairs or maintenance performed by a certified technician to ensure that the warranty is not voided.

Finally, if you are unsure about any aspect of your Jandy pool heater, it is always best to seek advice from a professional rather than risking damage to the unit or potential harm to yourself.

If the Heater Continues to Malfunction After Resetting

If your Jandy pool heater continues to malfunction even after resetting, it’s time to call a professional. Don’t attempt to fix the issue on your own, especially if it involves electrical or gas components, as this can be dangerous and lead to further damage or injury.

A qualified technician will have the knowledge and tools to diagnose the problem accurately and safely. They can determine whether your heater needs repair or replacement and advise you on the best course of action.

Remember, delaying the repair can result in more significant problems and can also be costly. A professional service call can save you time, money, and peace of mind in the long run.

So, if your Jandy pool heater is still not functioning correctly after resetting, don’t hesitate to contact a qualified professional to fix the problem and keep your pool at the optimal temperature.
