Customer Questions and Answers for Terminal Insulator Assembly by Whirlpool

This terminal insulator assembly isolates and supports an electrical connection where it passes through the appliance chassis. Replacing a cracked or heat-damaged insulator helps prevent shorts and restores a safe, reliable connection.

• Electrically insulates a live terminal from the metal cabinet or oven wall
• Provides a secure pass-through/mounting point for the element/wire connection
• Helps prevent arcing, shorting, and localized heat damage at the connection
• Typical symptoms: visible cracks or burn marks on the insulator, tripped breaker, intermittent or no heat due to a compromised connection

• Disconnect power at the breaker or unplug the appliance before servicing
• Access the terminal area; label or photograph wiring to ensure correct reassembly
• Transfer wires one at a time; reuse existing hardware if serviceable and tighten connections securely
• Inspect nearby wire ends/connectors and replace any that are heat-damaged or brittle
