Parts for Jenn-Air A159: Grill Cartridge Parts

This terminal block provides an insulated, secure junction for incoming power or harness leads inside the appliance. Replacing a cracked, loose, or heat-damaged block restores a safe, reliable connection and helps prevent arcing or intermittent power.

• Creates a fixed, insulated junction between external supply wires and internal appliance wiring
• Maintains tight screw-lug connections to minimize resistance and heat buildup
• Helps ensure steady power delivery to controls, motors, and heaters
• Common indicators of failure: melted/discolored block, burning odor, visible arcing, loose or stripped terminals, intermittent or no power

• Disconnect power at the breaker and verify zero voltage before servicing
• Photograph/label wire positions; transfer one lead at a time to the new block
• Tighten terminal screws firmly; do not overtighten into the insulator
• Inspect wire ends/ring terminals and strain relief; replace any heat-damaged components per the service information

This speed nut is a stamped metal retaining clip designed to hold screws or fasteners securely to appliance panels and trim. It provides a simple, vibration-resistant connection that keeps covers and components in place. What it does:

• Secures screws to thin sheet metal or panel edges where a threaded hole isn't available
• Provides a firm, vibration-resistant attachment for panels, trim, or small components
• Helps prevent screws from loosening or backing out during normal use
• Commonly used where a captive nut or clip is required for assembly or repair

• One speed nut / retaining clip

• Disconnect power and unplug the appliance before starting any repair
• Position the clip over the panel edge or hole so the screw can engage the clip's thread; press or tap gently until seated
• Use the correct screw size and avoid over-tightening to prevent deforming the clip or striping threads
• Wear gloves and eye protection when handling sharp sheet metal edges
