Is This the Right Part?

Common Symptoms

• A dryer function served by a loose, damaged, or open harness connection may be intermittent or not operate.
• A connector-related harness fault can produce an affected electrical function even when the connected component itself has not been confirmed faulty.

Check Before Replacing

• Disconnect power before accessing internal wiring.
• Visually inspect the accessible harness for pinched, chafed, heat-damaged, or visibly broken wires; do not probe energized circuits.
• Check that applicable harness connectors are fully seated and that terminals are not visibly backed out or damaged.
• Use the wiring diagram and technical sheet specified for the exact dryer model before attempting continuity testing.
