What the diagnostic covers

Find the cause before replacing expensive parts.

A pool heater that clicks, starts the fan, or attempts ignition without producing heat needs proper testing. Repeated resets often hide the real fault and delay the repair.

Pool Heater Experts checks the operating sequence, safety controls, system conditions, and visible equipment condition. The exact procedure depends on the heater model and the fault present.

Gas supply or pressure problemThe heater needs the correct inlet and manifold gas pressure during operation. A closed valve, undersized line, regulator issue, or pressure drop can stop ignition.
Ignition and flame-sensing faultA worn igniter, weak spark, poor grounding, damaged flame sensor, loose wiring, or failed ignition module can prevent flame confirmation.
Airflow or venting faultBlocked intake, damaged venting, blower faults, pressure-switch problems, or debris can interrupt the ignition sequence.
Water-flow safety openLow pump flow, dirty filter, bypass issues, pressure-switch faults, or closed valves can keep the heater from firing.

Common questions

Pool Heater Not Igniting? FAQ

Why does my pool heater click but not ignite?

The heater may have an ignition, gas-pressure, flame-sensing, airflow, or control problem. Testing the ignition sequence identifies where operation stops.

Should I keep resetting the heater?

No. Repeated resets do not repair the cause and can make diagnosis harder. Record the error code and request service.

What information should I send?

Send the brand, model number, displayed error code, postal code, and a clear photo of the rating plate.
