COMMON POOL HEATER PROBLEMS WE SEE
Why is my pool heater not heating?
Most of the time it’s low water flow, a dirty filter, or a problem with ignition or gas supply. If the heater isn’t getting proper flow or can’t ignite, it won’t produce heat.
Why won’t my pool heater turn on?
This can be caused by power issues, a tripped breaker, a faulty thermostat, or a safety switch shutting the unit down. Modern heaters won’t start if something isn’t safe.
Can a pool heater be repaired or does it need to be replaced?
Many issues can be repaired, especially with newer units. If the heat exchanger is damaged or the unit is older, replacement is often the better long-term option.
What should I check before calling for repair?
Check that the breaker is on, the filter is clean, valves are open, and the thermostat is set correctly. If everything looks normal and it still won’t run, it needs a proper diagnosis.
Is it worth fixing an older pool heater?
If the unit is near the end of its lifespan or needs major parts, replacement is usually the smarter investment. Smaller repairs on newer units are typically worth it.
Why is my pool heater turning on and off?
This is usually caused by poor water flow, overheating, or a sensor issue. The system is shutting itself down to prevent damage.
How long do pool heaters last?
Most pool heaters last around 7–12 years. Proper maintenance and water chemistry make a big difference in how long they hold up.
How much does pool heater repair cost?
It depends on the issue. Simple fixes like sensors or igniters are relatively inexpensive, while major components like heat exchangers cost more and may not be worth repairing.
