Key Takeaway:
- Understanding the capacitor is essential to diagnose and fix a malfunctioning well pump. There are two main types of motor capacitors: start capacitors and run capacitors, each serving a specific function in a pump motor. Single-phase motors use capacitors to start and for energy savings. A start capacitor gives the motor an extra electrical push to start it, while a run capacitor is an energy-saving device that is always in the motor circuit.
- The well pump capacitor plays a crucial role in maintaining a well pump motor’s efficiency. Signs of a bad well pump capacitor include weak pump thrust, the pump not turning, and not being able to hold electricity. Other warning signs are the pump not turning on, shutting down frequently, a burning smell, a delay in the pump starting, no voltage, and high electricity bills. Troubleshooting a bad well pump capacitor includes restoring electrical contacts, replacing the pressure switch, and testing the capacitor using a multimeter. It is essential to confirm the power is off before replacing the pressure switch or filing the contacts, using a voltage tester.
- If a pool pump’s capacitor needs to be tested, discharge it by touching the terminals with a screwdriver before testing. Test it using the lowest ohm setting on the multimeter and touch the leads to the capacitor prongs. If the meter doesn’t move or stays at zero, the capacitor is bad. Access to the capacitor can be found in a guide on changing the pump’s mechanical seals.
Understanding the Capacitor

A malfunctioning capacitor in your well pump system can cause various issues. In this section, we’ll explain the capacitor and discuss the two main types of motor capacitors. This information will help you diagnose and resolve problems with your well pump system in a timely and efficient manner.
Two Main Types of Motor Capacitors
Motor capacitors are a must-have for many motors, like pool pumps, ACs, and well pumps. There are two types: start capacitors and run capacitors. Start capacitors give a boost when starting the motor, while run capacitors provide a continuous supply of electricity to keep it running.
A table can help distinguish the two:
| Capacitor | Function | Voltage | Size |
|---|---|---|---|
| Start Capacitor | Provides Electrical Boost to Start the Motor | High Voltage | Larger |
| Run Capacitor | Supplies Steady Electricity to Keep Motor Running | Low Voltage | Smaller |
Which one you need depends on several factors: motor size, application, and voltage rating. Malfunction or damage can cause overheating, high energy use, or motor failure. So, watch for signs of a bad capacitor and address any issues quickly.
Without a working capacitor, your well pump won’t have enough power to do its job.
Importance of Well Pump Capacitor

The well pump capacitor is very important for an uninterrupted water supply. It is a significant part of the well pump system and regulates the electrical voltage. Without it, the motor may not start or its speed could be unstable, resulting in little water pressure or no water at all. The capacitor acts as a storage device and produces energy when needed, which helps the motor start and avoids overheating.
Faulty capacitors can cause issues like tripping circuit breakers, motor overheating, and humming or buzzing sounds.
Regular maintenance of the system is key to make it last. If there are signs of poor performance, like low water pressure or strange sounds, get it checked by an expert. By keeping up with maintenance and replacing the well pump capacitor when necessary, you can make sure there’s a continuous flow of water from the well.

Having a faulty well pump capacitor can be a frustrating experience for any homeowner. In this section, we will explore the signs of a bad well pump capacitor, so you can identify if it’s time for a replacement. From reduced water pressure to frequent pump cycling, we’ll discuss the common indicators of a faulty capacitor and what they mean for the performance of your well pump. Don’t let a bad capacitor catch you off guard – read on to know the warning signs.
The Well Pump Not Turning On
A faulty well pump capacitor can prevent the well pump from turning on, creating a water supply shortage. Follow these three steps to fix it:
- Check the electrical control box for a tripped breaker powering the well pump motor.
- Ensure the electrical contacts are functioning correctly, but disconnect power from the pump first.
- If the contacts aren’t functioning correctly, try restoring them briefly to see if it solves the problem.
If these steps don’t work, examine other parts such as wiring connections or the pressure switch’s operation. Here are a few tips:
- Before testing, use a multimeter to check for voltage issues or call a professional electrician.
- If you’re testing, remember to discharge pool pump capacitors first as they carry a charge that can cause shock or damage to testing equipment.
Failure to Continue Running
Capacitors are essential for proper well pump function. If a bad capacitor is present, the pump may start and stop quickly or won’t even start. To determine the problem, check the electricity supply. Disruptions can disconnect the contacts, stopping the energy flow. Also, look out for broken wires or burned switches. Use capacitors with the correct voltage rating to avoid stoppage or bursting. Finally, it’s important to get a professional to inspect and prevent issues for efficient operation. By looking out for common issues, operators can prevent extensive damage and ensure uninterrupted pump function.
Burning Smell
You smell something burning? Don’t ignore it! It could be your well pump capacitor overheating. This can come from running it too long or from incorrect voltage.
Other signs of a failing well pump capacitor:
- Turning off
- Slow response
- No voltage delivery
- Higher energy bills
- Not able to run
Stop using it as soon as you smell something and get an electrician. John called a technician right away when he smelled a burning odor. The technician found out that it was from too much use and the machine’s parts had burned. Without help, it could have been much worse!
If your well pump is slow, it could be the capacitor. To avoid bigger problems, try to keep up with maintenance and fix issues quickly.
Late Response
Well pumps might show a delayed response, which is a sign of a faulty capacitor. Capacitors store energy and give the motor an electrical burst to start. If the motor struggles to start, components will suffer wear and tear, leading to failure.
A worn-out capacitor often causes delayed response. Over time, they can’t store energy correctly, so the motor takes longer to start. Overloaded circuits or bad wiring connections can also affect starting.
If your pump takes too long to turn on, or if it takes ages for water to flow, time to replace the capacitor. This’ll improve reliability and reduce stress on other components, saving you money in repairs.
No voltage? No water. Get a bucket and start walking.
No Voltage
Capacitors are key for efficient well pump operation. If the motor is not getting voltage, it may be a sign of a bad capacitor. This is because capacitors store and release electrical energy to start the motor. If the energy isn’t released, the motor won’t get enough voltage and can malfunction.
A faulty capacitor can lead to high electricity bills due to inefficient motor operation. It is important to diagnose and fix capacitor issues fast, to avoid costly repairs and downtime.
It is clear that if the well pump is not maintained, electricity bills can be driven up. Therefore, any capacitor issues must be dealt with quickly to avoid extra expenses.
High Electricity Bills
Capacitors are key in controlling power used in a well pump. This helps the motor run efficiently and adds years to its life. But, a bad capacitor causes inefficiency, heat, and lower performance, leading to high electricity bills.
Damaged capacitor? Water supply won’t improve but power consumption will increase. When the capacitor’s efficiency drops, the motor uses more current. Result? Higher energy bills.
You must take care of any electrical issues with your well pump quick. This stops more damage and saves on utility bills.
If you have high electricity bills, try troubleshooting methods to get your well pump working again.

If you rely on a well for your water supply, a faulty well pump can cause significant disruptions. It is crucial to troubleshoot a malfunctioning well pump capacitor to identify the issue. In this section, we will cover how to do just that. We will discuss restoring the electrical contacts temporarily, testing a water pump capacitor using a multimeter, and discharging a pool pump capacitor before testing. Each of these sub-sections will provide you with the knowledge you need to effectively troubleshoot a faulty well pump capacitor.
Restoring the Electrical Contacts Temporarily
Turn off power to avoid damage. Check contact points for corrosion or damage. Clean bonding and mounting surfaces. Remember, attempting repairs without knowledge can be dangerous. Test new well pump capacitors. Replace components for performance and power efficiency. Beware of obsolete techniques. Following these steps, you can temporarily restore electrical contacts until professional repairs can be made.
Testing a Water Pump Capacitor using a Multimeter
A multimeter is a must-have when it comes to testing the water pump capacitor. It’s great for measuring electric current, voltage, and resistance. Here’s what you do when testing your water pump capacitor using a multimeter:
- First, disconnect the motor from the power source.
- Set your multimeter to capacitance measurement mode.
- Before testing, discharge the water pump capacitor by shorting out its terminals with a tool like a screwdriver or pliers.
- Check the capacitance of the capacitor in microfarads (µF). This should be within 6 percent of the manufacturer’s instructions.
- If you’re still unsure, try testing another capacitor in good condition. Compare the readings from both capacitors.
- If there is no discharge, or if the reading is close to zero or stays the same after connecting and disconnecting the multimeter leads, contact an expert electrician.
Remember: always discharge testers that contain energy.
To avoid more expensive electricity bills, regularly test your well pump capacitors. Do this at least twice yearly. If you haven’t done this but are already noticing signs of failure, troubleshoot immediately to prevent further damage!
Discharging a Pool Pump Capacitor before Testing
Safety when testing pool pump capacitors is key. Before testing, it’s vital to discharge the pool pump capacitor to avoid a shock that could lead to serious harm or even death.
To do this safely, follow these steps:
- Turn off the pool pump power via the circuit breaker or switch.
- Find the pool pump capacitor – it’s usually cylindrical and silver or gray.
- Use an insulated screwdriver to short out both terminals on the capacitor.
- Hold the screwdriver in place until a spark appears, showing it’s discharged.
- Check there is no voltage using a multimeter.
Discharging the pool pump capacitor won’t always fix issues, like a pump that won’t turn on. If unsure, get a professional technician.
Be aware that capacitors may have voltage, even when disconnected from power. Treat all capacitors as if live until confirmed otherwise.
A cautionary tale: one pool owner attempted to fix his pool pump without discharging the capacitor first. This resulted in a shock that sent him to the hospital and costly medical bills. Safety first!

How can I temporarily fix a well pump that only works when the tube under the pressure switch is banged on?
To fix a well pump that only works when the tube under the pressure switch is banged on, the electrical contacts may need to be restored temporarily. Turn off the power and use a voltage tester to confirm it is off before beginning. Open the contacts and file off any burned or pitted areas using a nail file or emery board. This fix is only temporary, and the pressure switch should be replaced as soon as possible. Always confirm the power is off before replacing the pressure switch or filing the contacts, using a non-contact voltage tester. This information was provided by Family Handyman.
How can I check if a pool pump’s capacitor is still working?
To check if a pool pump’s capacitor is still working, use a multimeter. Before testing or removing the capacitor, discharge it by touching the terminals with a screwdriver. A capacitor is a device that stores electricity and can be found in various electronic devices and power plants. Single-phase motors use capacitors to help them start and for energy savings. There are two main types of motor capacitors – start capacitors and run capacitors. A start capacitor is used to give a motor an extra electrical push to start it turning and isn’t used for more than a second or two, while a run capacitor is an energy-saving device that is in the motor circuit at all times. If a start capacitor fails, the motor will not be able to begin turning, while a bad run capacitor can cause various problems such as not starting, overheating, and vibrating. Run capacitors are heavier and more durable than start capacitors since they are always used when the motor is running. Improper current or voltage and overheating due to being used beyond their intended purpose can also cause capacitors to fail.
What causes a water pump capacitor to fail?
A water pump capacitor helps the water pump turn and the electric water pump dynamo gain more power. It wears out over time and can’t work as well when broken. Signs of a broken capacitor include weak pump thrust, the pump not turning, and not being able to hold electricity. Weak pump thrust happens when the dynamo doesn’t get as much power as it did before. The pump won’t turn because the dynamo isn’t turning steadily enough for the capacitor to work correctly. The capacitor helps the dynamo turn by keeping the current it needs to keep riding. If the capacitor can’t store electricity, it’s another sign that it’s broken. To measure a water pump capacitor with an analog multimeter, provide the instrument, set the selector to the Ohm-meter position, and make sure the multimeter is in good shape.
