Why Pool Heaters Fail After Long Off-Seasons

Many pool owners only use heaters during specific months, leaving them idle the rest of the year. This downtime can contribute to problems when the system is turned back on.

Here’s what often happens:

• Stuck valves or sensors – Parts may seize due to lack of movement or buildup from stagnant water.
• Clogged burners or filters – Debris and moisture settle during off-months, causing airflow and ignition issues.
• Damaged seals or connections – Time and temperature changes can dry out seals, leading to leaks or weak performance.
• Battery or wiring issues – Long periods of inactivity can drain batteries or expose corroded connections.
• Corrosion inside components – Even if the unit wasn’t used, exposure to humid air or stored chemicals may cause rust.
