Pump will not start at all; no hum, no sound, but power is available at the equipment pad.

Safety First: Use a non‑contact tester and multimeter carefully; turn OFF power before tightening any connections.

• Check breakers and GFCI: Inspect the pool sub‑panel and reset any tripped breakers or GFCI outlets feeding the pump.
• Bypass external timer: If a mechanical or digital timer is used, set it to ON or temporarily bypass it to see if the pump starts.
• Verify voltage at pump: Remove the Rheem pump terminal cover and, with power ON, measure voltage at the LINE terminals. If no voltage is present, trace back to the panel or timer.
• Inspect internal fuses: Some Rheem controls have internal fuses. With power OFF, check and replace any blown fuses with identical ratings.
• Replace control module: If correct voltage reaches the control but the display is dead and the motor does not energize, the Rheem control module is likely defective.
