Why Does My Pool Pump Hum But Won’t Spin?
Having a pool in your backyard is a great way to enjoy the outdoors and stay cool during hot summer days. However, owning a pool also means having to take care of it and ensuring that all the equipment is working properly. One of the most important pieces of equipment is the pool pump, which is responsible for circulating the water and keeping it clean. If your pool pump is humming but won’t spin, there could be several reasons why.
1. Blockage in the Pump
One of the most common reasons why a pool pump hums but won’t spin is because of a blockage in the pump. This can happen when debris or leaves get stuck in the impeller or the skimmer basket. When this happens, the pump will try to turn but will not be able to because of the blockage. To fix this issue, you will need to turn off the pump and remove any debris or leaves from the impeller or skimmer basket.
2. Motor Capacitor Failure
The motor capacitor is responsible for starting the pool pump motor. If the capacitor fails, the pump will not start properly and will only emit a humming sound. This is a common issue that can be fixed by replacing the capacitor. It is important to note that replacing the capacitor should only be done by a professional as it involves working with electrical components.
3. Low Voltage
If the voltage to the pool pump is too low, it may not be able to start properly and will only hum. This can be caused by a faulty circuit breaker or a bad electrical connection. You can check the voltage by using a voltmeter. If the voltage is low, you should call an electrician to fix the issue.
4. Locked Motor
If the pool pump motor is locked or seized, it will not be able to turn and will only hum. This can be caused by a lack of lubrication or a faulty bearing. If the motor is locked, you will need to call a professional to fix the issue as it can be dangerous to work with a locked motor.
5. Broken Impeller
If the impeller in the pool pump is broken, it will not be able to circulate the water and the pump will only hum. This can be caused by a build-up of debris or wear and tear over time. To fix this issue, you will need to replace the impeller.
In conclusion, if your pool pump is humming but won’t spin, there could be several reasons why. It is important to identify the issue and fix it as soon as possible to prevent any further damage to the pump or the pool. If you are not comfortable working with electrical components or pool equipment, it is best to call a professional to fix the issue.
