Where is my well pump capacitor located?

There are usually 2 capacitors inside a pump control box, a start capacitor and a run capacitor. A start capacitor is considered a consumable part in a water pump system, and should be replaced every 3 years.

What causes well pump capacitor to fail?

Overheating is a primary cause of a failed start capacitor. If a start capacitor stays in the circuit too long, it will overheat and fail. If a failed start capacitor is discovered while troubleshooting, the start relay should be inspected as the possible cause.

Does a well pump have a capacitor?

Capacitors are used in many electrical motors, not just in well pumps. This boost of power allows the motor to overcome the inertia of staying still (which requires more energy than simply keeping a motor running once it’s already on). If the capacitor goes bad, the pump may not start.

What does a capacitor do in a well pump?

Capacitors. Control box capacitors play an integral role in your submersible well pump system. They are responsible for starting up or running the motor. Over time, the well pump capacitors wear out, lose capacitance, and need replacing. Continued use may result in the capacitor blowing out, potentially causing damage to your motor or control box.

What does a capacitor do in a pool pump?

A capacitor is like the battery in your car, but for your pool pump motor. A pool pump start capacitor provides the extra energy needed while starting, to reach 3450 rpm quickly.

What is the start capacitor for a bore pump motor?

A 45 microfarad capacitor often used with a 1.1kw bore pump motor In most submersible pumps the capacitor is a dual start/run capacitor that does both. A capacitor used with a bore pump motor is normally perfectly cylindrical and about half the diameter of a soft drink can. It should not have black marks or be ruptured.

What is a well pump control box?

A well pump control box is basically the brain of a water system because it handles many tasks to keep the system functioning properly. Pump control boxes are responsible for monitoring the flow of water and controlling a water pump to keep it at the desired level.
