U.S. Motors digital pool pump shows E07 and shuts down shortly after starting, especially in hot weather or when running at high speed.

Safety first: Turn off power before removing any covers. Electronics can remain hot; allow time to cool.

• Check ventilation: Ensure there is adequate clearance around the U.S. Motors drive/control housing. Remove leaves, dirt, or obstructions blocking vents.
• Inspect cooling fan: If the drive has an internal fan, remove the cover and verify the fan spins freely and runs when the pump is operating. Replace the fan if seized or not running.
• Reduce ambient heat: Provide shade over the equipment pad or relocate the drive out of direct sun if possible. Avoid enclosing the pump in a tight, unventilated box.
• Lower operating speed: Temporarily reduce maximum RPM or duty cycle in the controller settings to reduce heat generation.
• Reset after cooling: Allow the drive to cool completely, then power cycle and clear E07. If the error recurs quickly under normal conditions, the temperature sensor or drive module may be failing.
