Safety Information
WARNING: Electrical components can store dangerous charges. Always ensure power is disconnected and the capacitor is fully discharged before handling. Consult a qualified electrician if you are unsure about any procedure. Failure to follow these instructions may result in electric shock, fire, or serious injury.
- Always disconnect power before working on electrical systems.
- Discharge the capacitor using a properly insulated tool or resistor.
- Wear appropriate personal protective equipment (PPE), including insulated gloves and safety glasses.
- Ensure proper wiring and connections to prevent short circuits.
Setup and Installation
The Genteq Z23S3720M capacitor is designed as a direct drop-in replacement, meaning no wiring changes or adapters are typically needed for compatible systems. However, always verify compatibility with your existing unit's specifications before installation.
- Power Disconnection: Turn off the main power supply to the appliance or system where the capacitor will be installed. Verify power is off using a voltage tester.
- Capacitor Discharge: Carefully discharge the old capacitor using a resistor or insulated screwdriver across its terminals. A spark may occur, which is normal.
- Removal of Old Capacitor: Note the wiring connections of the old capacitor. Take a photo if necessary. Disconnect the wires and remove the old capacitor from its mounting bracket.
- Installation of New Capacitor: Place the new Genteq Z23S3720M capacitor into the mounting bracket. Connect the wires to the corresponding terminals. Ensure connections are secure and tight.
- Power Restoration: Once the capacitor is securely installed and all connections are verified, restore power to the system.

Operating Principles
The Genteq Z23S3720M is a run capacitor, commonly used in HVAC systems and other motor applications. Its primary function is to store electrical energy and release it to create a phase shift in the motor's windings, providing the necessary torque for efficient starting and continuous operation. This capacitor helps maintain a stable current flow, improving motor efficiency and longevity.
Maintenance
Capacitors are generally maintenance-free components. However, periodic inspection is recommended, especially if the connected appliance shows signs of reduced performance. Look for:
- Bulging or swelling of the capacitor casing.
- Leaking fluid or residue around the terminals.
- Burn marks or discoloration on the terminals or casing.
- Audible humming or buzzing from the capacitor.
If any of these signs are present, the capacitor may be failing and should be replaced by a qualified technician.
Troubleshooting
If the appliance or motor connected to the capacitor is not functioning correctly, the capacitor may be a contributing factor. Common symptoms of a failing capacitor include:
- Motor hums but does not start.
- Motor starts slowly or struggles to reach full speed.
- Appliance cycles on and off frequently.
- Reduced cooling or heating performance in HVAC systems.
To diagnose a capacitor, it is recommended to use a multimeter with capacitance testing capabilities. Always discharge the capacitor before testing. A reading significantly lower than the rated capacitance (20 uF for this model) indicates a faulty capacitor that requires replacement.
