A water source heat pump (WSHP) capacitor is an electrical component that stores and releases electrical energy to help start and run the heat pump's compressor and fan motor. The capacitor works by creating a temporary electrical charge that is used to start the motor and keep it running.
When the heat pump is turned on, the capacitor sends an electrical charge to the compressor and fan motor to help them start up quickly and efficiently. Once the motor is running, the capacitor helps to regulate the flow of electricity to ensure that the motor runs smoothly and efficiently.
Over time, the capacitor can become worn or damaged, which can cause issues with the heat pump's performance. Signs that the capacitor may be failing include a clicking or buzzing sound coming from the heat pump, the motor running slower than usual, or the heat pump not starting up at all. In these cases, it's important to contact a qualified HVAC technician to diagnose and replace the faulty capacitor.
