• Intermittent power supply or electrical issues
• Burnt or melted wires or connectors
• Appliance not receiving or responding to electrical signals correctly
• Visible damage or corrosion on the terminal block

Causes of a bad terminal block kit include excessive heat exposure, loose connections, moisture or water damage, or simply wear and tear over time.

This OEM part is also compatible with Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore models. 

The Surface Element is an OEM part for Whirlpool ranges. This part provides heat to the cooking surface, allowing for the preparation of food.

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
