Ac Fan Start Cap Wiring
Rule of thumb on wiring the capacitor is.
Ac fan start cap wiring. Large electric motors with a high starting torque like an air conditioner s compressor motor often use a start capacitor kit. The start capacitor gives a fan motor the torque it needs to start spinning then stops. The relay disconnects the start capacitor from the motor s electrical circuit once the motor has reached operational speed. R run wire connector.
In this video zack psioda explains how many dual run capacitors are wired in heat pump and. While the run capacitor stays on giving the motor extra torque when needed. See how to install wire up an air conditioner compressor blower motor or fan motor hard starting capacitor. Hvac shop talk podcast represents the blue collar boys and girls in the skilled trades especially hvac.
Usually the fan motor uses brown insulation on its capacitor wire. S start wire connector. Step 7 press the wire connector on the compressor s wire with the start or s function onto the capacitor s herm terminal. If the start capacitor fails the motor will most likely not turn on.
On many systems these terminals may be labeled so that the three leads on a start run capacitor can be wired correctly. A start capacitor kit contains a start capacitor relay and wires. C common connector. Push the wire connector on the fan motor s wire with the capacitor or cap function onto the capacitor s terminal with the fan label.
