This strain relief keeps the appliance's power or internal wiring secure where the harness passes through the cabinet, reducing stress on wires and helping prevent frays or loose connections. It's a small replacement part that restores proper cable routing and strain protection. What it does:

• Secures and protects wiring where the harness passes through a chassis or housing
• Prevents wire abrasion and reduces stress at the entry point
• Helps stop intermittent electrical connections caused by loose or pinched wiring
• Restores correct cable routing for safer, longer-lasting wiring

• Disconnect power before servicing; follow all safety instructions for your appliance
• Remove access panels as needed to reach the harness entry point
• Seat the strain relief fully in the opening and route the wiring through the boot without pinching
