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

• Drives relays/switching to power components such as motors, heaters, valves, or fans
• Stores the control logic for modes and settings
• Typical symptoms include no response to controls, won't start, intermittent shutdowns, or error codes

• 1 electronic control unit (board/module)

• Disconnect power at the breaker or unplug the appliance before servicing
• Use ESD precautions; handle the board by the edges to avoid static damage
• Label/photograph all connectors and transfer any brackets or covers from the original board
