Pump Control Box Repair
Repair of control box capacitors, relays, and connections that keep a well pump from starting.
Many well pumps rely on a control box mounted near the pressure tank. Inside are capacitors and relays that help the motor start and run. When one of those parts fails, the pump may hum, overheat, or not start at all.
Pump control box repair targets those electrical components directly, often restoring water without the need to pull the pump from the well.
Symptoms of a Control Box Problem
- The pump hums but does not start
- A burning smell or discoloration near the control box
- The overload protector trips repeatedly
- A bulging or leaking capacitor
- Intermittent water that comes and goes without a pattern
Testing and Repairing Control Components
We test the capacitors, relay, and overload protector with the proper instruments to identify which component has failed. Connections inside the box are checked for heat damage and corrosion.
Failed components are replaced with parts suited to your pump motor. After repair, we confirm that the pump starts smoothly and draws normal amperage.
