GE Pump Shuts Off After 3 Minutes: Motor Brushes or Relay

Lake Pump Runs 3 Minutes Then Stops: Electrical or Motor Fault

GE 1.5 HP 220V pump, no pressure tank, direct to irrigation. Primes, runs 3 min, cuts off. Repeats after cooldown.

Since it pumps directly, the shutdown is not pressure-related.

Worn motor brushes – Motor runs until heat expands brushes, losing contact. Cools, works again. Some motors allow brush replacement.
Bad relay/contactor – Overheats and opens.

Have a motor/pump service person inspect. Don't guess—running it damaged worsens the fault.
