Locate the dedicated circuit breaker for the HVAC unit in the main electrical panel and switch it to the "Off" position. Ensure the wires are stripped to the correct length—usually about 1/2 inch—and twisted tightly before securing them under the terminal screws.
How to Wire Run Capacitor HVAC: Step-by-Step Process
There are typically two types: the run capacitor, which remains engaged to improve motor efficiency and torque during operation, and the start capacitor, which is only used for a few seconds during startup. Simply turning the thermostat to "Off" is insufficient.
Additionally, check the microfarad (μF) rating and voltage rating on the side of the old capacitor. Wiring a capacitor for HVAC applications is a fundamental skill for technicians and a common point of failure for homeowners.

Tighten the screws firmly to ensure good conductivity and to prevent arcing. The capacitor stores an electrical charge and releases it to the start winding of the motor, creating a phase shift that generates the necessary rotational force.
