How do you test a well pump control box?
How to Test a Well Pump Control Box. Technicians should test a well pump's control box before pulling a nonworking pump from the well. When the water tank's pressure switch detects low water pressure, its switch closes, which turns on the electricity to the control box.
How to choose the right pump for your control box?
The control box voltage must match the pump voltage. It’s best to decide which kind of pump you will use, and then compare the voltage and amperage to the ratings of the control box. There are several kinds of control types that are used to control pumps: Float switch – Rises and lowers with the liquid level.
How do you test a pressure switch on a well?
Replace the wire connectors after testing the control box's capacitor. Turn on the circuit breaker. Turn a multimeter to its "VAC" setting. Open a faucet. This lowers the water pressure in the well's storage tank, which causes the well's pressure switch to turn on. Place the multimeter's probes on the control panel's "L1" and "L2" terminal.
How do you test a control box capacitor with a multimeter?
Turn a multimeter to the "Ohm" setting. Touch the multimeter's probes on the capacitor's terminals and watch the meter's reading. The meter should reach infinite, fall back slightly, then reach infinite again. If it does not, then replace the capacitor. Replace the wire connectors after testing the control box's capacitor.

Can you run a well pump without a control box?
The short answer is yes. Most pumps will work without a control box. But here's the rub – if you want your pump to run better, for more hours in the day, if you want to use a float switch, and if you want to protect your pump from voltage and current spikes, then a control box is an excellent addition to your system.
What does a pump control box do?
(3) Pump Control Box – protects submersible pumps from low or high voltage, a drop in water level, low yield wells, clogged well screens, malfunctioning pumps and motors, and rapid cycling. Pump control boxes usually have microprocessors that monitor power-line voltage and pump motor power draw.
How do I reset my well pump control box?
Hold the reset lever in the start position until the pressure builds up and the gauge reads over 40 PSI; then let it return to the AUTO position. The pump should now run on its own and continue until the pressure reaches the cut out setting, (usually between 50 - 60 PSI), and then shut off.
Can pumping machine work without capacitor?
The motor will run fine without the capacitor. However, the problem comes if the motor stops and tries to restart. Say for instance you have a power blip for a second or two. The pump will shut down and not be able to restart, therefore ruining the motor.
Does a 2 wire well pump need a control box?
Two wire well pumps do not use a control box. All the elements already come built within the motor or pump house itself. This allows for easier installation. However, if any of the starting components fail, the pump will have to be pulled up and the whole motor will have to be replaced.
Are pump control boxes interchangeable?
The pumps are bolted onto the motors (with matching splined shaft). However, one major manufacturer makes its own motor and control box, which are not interchangeable. As for the others, motors and control boxes may be interchanged as long as horsepower, phase, and voltage are a match.
Does a 3 wire well pump need a control box?
While two-wire well pumps do not require a pump control box, three-wire submersible well pumps do. Control boxes contain the starting circuits for well pumps.
Can you run a well without a pressure switch?
You can run a well pump with a pressure tank. The purpose of a pressure tank is to keep the water pressure at a constant level. Without the pressure tank, your well pump needs to work harder and can go into a cycling state where it turns on and off quickly and constantly.

What causes automatic pump control failure?
The single most common reason a pump controller fails is due to a build-up of 'muck' in the internals of the controller. Typically, tank water collected off a roof catchment contains bacteria which with the addition of summer heat can develop bacterial growth.
How do you adjust a water pump controller?
If you want the water pump to turn OFF (cut out or cut-off) at a higher water pressure, turn this nut clockwise or "tighter". Adjusting the pressure on this spring shifts just the pump cut-out pressure up (clockwise) or down (counter-clockwise).
Why pressure pump keeps turning on and off?
A blockage in the water supply piping. For example, a clogged or nearly clogged water filter can cause the pump control to cycle on and off rapidly. This is because the blockage causes water pressure (between the pump and the filter) to rise very rapidly when the pump turns on.

How to check voltage on a 3 wire submersible pump?
Set an ohmmeter to match the voltage on your 3-wire submersible well pump. Turn off the power to your well pump, hook one wire from your ohmmeter to the ground and the other wire to the colored ground cable. Make sure that the ohmmeter reads OL (Open Lead) so that you know that your well pump is powered correctly.
What does an ohmmeter read?
Before beginning any testing, be sure that your well motor is not on any power supply. An ohmmeter reads the resistance of items which do not have any power to them. If you test your engine with the electricity on, your ohmmeter may malfunction. At the very least, you won’t be getting any good readings.
Why are three wire pumps more prone to failure?
As a result, three-wire well pumps are more prone to potential faults because more can go wrong. But those parts are easier to access because everything is segmented . The final difference comes from the horsepower behind the motors.
