Description

This microtemp thermal limiter is a temperature cutout designed to protect the appliance from overheating by interrupting power when temperatures exceed safe limits. It helps prevent damage to heating components and reduces fire risk. What it does:

• Monitors local temperature and opens the circuit when an overtemperature condition occurs
• Stops heat production when triggered, causing no-heat or intermittent-heat symptoms
• Acts as a safety device to prevent overheating of heating elements or nearby wiring
• Will require replacement if it no longer shows continuity at room temperature

What's included:

• One microtemp thermal limiter

Install notes:

• Disconnect power to the appliance before accessing or replacing the limiter
• Located near the heating element or air path; refer to service manual for exact placement
• Handle the limiter and its leads carefully to avoid damage; secure wiring connections when reassembling
• Test the old limiter for continuity with a multimeter to confirm failure before replacing
