Idler Pulley
An Idler Pulley is a common part in many household appliances, especially in dryers and washing machines. It's like a wheel that helps guide belts that make machine parts move smoothly. Think of it as a guide wheel that doesn't power anything but keeps the main drive belt running in the right direction and with proper tension. When someone mentions this in their resume, it usually means they have experience with appliance repair, particularly with belt-driven systems like those found in laundry equipment, exercise machines, or other mechanical devices.
