Run Capacitor
A Run Capacitor is an essential electrical part found in many household and commercial appliances, particularly in air conditioners, refrigerators, and electric motors. Think of it like a small battery that helps keep motors running smoothly after they start up. Unlike regular batteries, it works continuously while the appliance is operating. When someone mentions this in their resume, they're typically talking about their experience in diagnosing, replacing, or maintaining these components, which is a common task in appliance repair and HVAC maintenance work.
