Pahlén pool pump will not start at all, no humming, but power is available at the equipment pad

Safety first: Isolate power at the main breaker before opening any electrical enclosures. Use a multimeter only if you are trained.

• Check external controls: Verify that any time clocks, automation systems, and the Pahlén controller are calling for the pump to run.
• Inspect control box: With power off, open the Pahlén control panel and look for tripped manual reset overloads or burnt contactors. Reset overloads if present and investigate the cause.
• Test voltage at motor: A qualified technician should confirm that rated voltage reaches the motor terminals when a start command is given.
• Motor continuity: If voltage is present but the motor is dead silent, the windings or internal thermal protector may be open, requiring motor replacement.
