Start Capacitor
Cylindrical electrical component in the outdoor unit that provides the starting torque needed to start the compressor and fan.
What is Start Capacitor?
When the start capacitor degrades or swells due to summer heatwaves, the indoor unit blows like a regular fan while the outdoor compressor hums and fails to start.
