• Helps prevent looseness or separation that can disrupt performance
• Direct replacement for broken, brittle, or deformed connectors
• Can resolve intermittent operation traced to a poor connection at this junction

• 1 connector

• Disconnect power and, if applicable, shut off water before servicing
• Note orientation and positions before removal to ensure correct reassembly
• Seat the connector fully until any locking features engage; do not force
• Inspect mating parts for wear or damage and replace if necessary

This interconnect jumper wire restores a direct electrical connection between control components so your appliance can communicate and operate correctly. It replaces a damaged or broken harness jumper to help recover lost functions. What it does:

• Carries low-voltage signals between control boards, switches, or sensors
• Replaces frayed, broken, or burned jumper leads that cause intermittent operation
• Commonly used when controls fail to respond, cycles stop, or displays/indicators behave erratically
• Maintains original routing and connector fit to preserve factory wiring layout

• One interconnect jumper wire

• Disconnect power to the appliance before servicing to avoid shock or damage
• Verify connector orientation and seat firmly; avoid forcing mismatched plugs
• Route away from heating elements and moving parts; secure with existing clips or ties
