Safety: Turn off power and wait for the fan to stop completely before touching it.

Checks:

Inspect fan area: Remove any leaves, plastic bags, or objects obstructing the fan. Ensure the fan spins freely by hand.
Check for wobble: A bent fan blade can overload the motor; visually inspect and replace if damaged.
Inspect wiring: Look for loose or burnt connectors at the fan motor and on the main control board.
Capacitor (if fitted): Many Poolex units use a start/run capacitor for the fan. A bulged or leaking capacitor should be replaced with an identical Poolex fan motor capacitor.

Fan motor replacement:

If the fan does not start even when pushed by hand (with power off), the motor may be failed.
Order the correct Poolex fan motor assembly for your model.
Disconnect wiring, remove mounting screws, and swap the motor and fan blade as a unit if possible.
Restore power and verify that FA is cleared and the fan runs smoothly.

If you are not comfortable working around moving parts and mains voltage, contact a professional.

Poolex pool heater shows FA and does not start the compressor.
