Common Monroe County Pool Heater Problems and When To Call A Professional

There’s nothing quite like jumping into a warm, inviting pool—until your heater decides to stop working. Whether your pool heat pump isn’t turning on or you're dealing with inconsistent temperatures, understanding common issues can help you decide when it’s time to troubleshoot or call in the pros.

At United Heating & Air, we know how important it is to keep your pool comfortable and usable throughout the warm months in Monroe County. Here’s a quick guide to common pool heater problems and when to contact the experts for pool heater repair.

1. Your Pool Heat Pump Is Not Turning On

This is one of the most frequent complaints we hear. If your pool heat pump isn't turning on, check the basics first:

• Is the power supply connected? This means checking if the heater is actually plugged in or if the hardwired connection is secure. Sometimes, plugs can get accidentally pulled out or connections can loosen. Also, ensure there hasn't been any sort of power outage or interruption to the outlet or circuit that supplies the heat pump.
• Is the circuit breaker tripped? Go to your electrical panel and check the breaker that controls the pool heater's power. If the breaker has "tripped" (switched to the off position or a middle position), reset it by first switching it fully off and then back on. If the breaker trips again immediately, there's likely an electrical fault, and you should not attempt further troubleshooting. Contact a professional electrician or HVAC technician.
• Is your thermostat set correctly? Verify that the thermostat is turned on and set to a temperature higher than the current pool water temperature. Also, make sure it's in the correct mode (e.g., "Heat" or "On" rather than "Off" or "Cool"). Some thermostats have safety features or lockouts, so check the user manual to ensure no settings are preventing the heater from turning on.

If all seems normal and your heater still won’t power up, you may be dealing with a faulty capacitor, blown fuse, or internal wiring issue. That’s when it’s time to bring in a pro.

2. Inconsistent Water Temperature

If your pool water heats up one day but not the next, it could be a thermostat calibration issue or a dirty filter restricting water flow. In other cases, failing sensors or a malfunctioning control board might be to blame.

A professional technician can quickly test components and recalibrate your system to ensure a steady, comfortable temperature.

3. Low Water Flow or Dirty Filters

Pool heaters require a steady flow of water to function properly. A clogged filter, blocked pump, or closed valve can cause your heater to shut down for safety. Clean your pool filter regularly and make sure your pump basket is clear of debris.

Still having issues? It might be a sensor or pressure switch problem—something our technicians can easily inspect and fix.

4. Pilot Light or Ignition Failure

For gas pool heaters, the pilot light or electronic igniter is essential. If the pilot won’t stay lit or won’t ignite at all, it could be caused by:

• A dirty burner or orifice: The burner is where the gas ignites to produce the heat. The orifice is a small opening that precisely controls the amount of gas flowing to the burner. If either of these components gets dirty or clogged with debris, rust, or other buildup, it can disrupt the flow of gas and prevent proper ignition. 
• A bad thermocouple: A thermocouple is a safety device that senses whether the pilot light is lit. If the pilot light goes out, the thermocouple signals the gas valve to shut off the gas supply, preventing a dangerous gas leak. If the thermocouple itself is faulty, it might not be able to sense the pilot light correctly.
• Gas supply issues: This refers to any problem with the supply of gas to the heater. It could be a problem with the main gas line to your property, a partially closed gas valve for the pool heater, or a leak in the gas line leading to the heater. Low gas pressure can also cause issues with ignition and the pilot light. If there's insufficient gas flow, the pilot light might be weak or unable to stay lit, and the main burner won't ignite. Gas supply issues can be very dangerous, so it's crucial to have a professional diagnose and fix any potential gas leaks or pressure problems.
  
  

These problems can be dangerous to handle on your own—always call a professional for gas heater repair.
