Pool heaters are installed to maintain optimal water temperature even during cold days. Even though Las Vegas is known for its long summers, the temperature during the winter can drop to 39°F. Owning a pool heater allows you to use the pool longer and protects it from damage that can happen during the cold, like cracked tiles or frozen pipes.

Using this device all year long can sometimes cause heater defects. Some defects and faults can be easily fixed, but some require professional service. So, before calling a professional, let’s see if you can repair the pool heater yourself.

Read the Manual, Check For Error Codes, and Search Online 

New heat pumps come with a manual, and it is essential not to throw it away. The manuals contain a description of the device’s parts and an explanation of error codes, making it easier for you to understand what is wrong with the heater. 

Manuals can sometimes even have basic troubleshooting tips. If the problem is not explained in the manual, try searching online. Blogs can help you find solutions.

We will help you discover the common pool heater malfunctions and how to try to repair them.

The Pool Heater Fails to Turn on or Won’t Stay on

Reasons that can cause this are:

  • The temperature is not set right. The temperature of the heater must always be higher than the pool water. Raising the temperature will help the heater to start working.
  • It has a broken or clogged filter. This is one of the most common problems the heater won’t start working. Check the filter and the pump for dirt and clean it. Turn the heater back on.
  • The pilot light isn’t on. Check your pool heater’s venting, air supply, and gas pressure for the pilot light to be lit. See if the pilot tube is clogged or broken.
  • The gas valve is off. If the gas valve is turned off, the heater will not work because there is insufficient gas to power it. Turn on the valve, and the heater will start working.

Not Enough Pressure

A constant water flow is essential for your pool heater to function correctly. The heater will not turn on if it doesn’t get the optimum operating pressure. Check the pool pump, filter, and valves to ensure the water circulates properly. Clean the dirt from the filter and open the valves. Ensure you are not using several water sources simultaneously, which can reduce the pressure.

Pool Heater Cycling

Cycling means your heater is constantly and irregularly turning on and off. This can happen because of electrical issues or lousy water chemistry. Imbalanced water chemistry can lead to corrosion, potentially harming the inside of your pool heater and pump. Check the thermal regulators, pressure sensors, and high-limit switches for corrosion. See if you can clean them. If not, replace them.
