Nordyne 1039636R L200-40F Flame Rollout Switch

Description

Nordyne 1039636R L200-40F Flame Rollout Switch Overview

The Nordyne 1039636R is an OEM flame rollout switch designed to protect furnaces from the hazardous condition known as flame rollout — when burner flames extend beyond the combustion chamber and into the surrounding area. This critical safety device monitors heat levels near the burner assembly and interrupts furnace operation if temperatures exceed the rated threshold, preventing potential fire damage, heat exchanger failure, and unsafe operating conditions.

Key Features

• OEM Nordyne replacement part — engineered for direct, reliable fit
• L200-40F rated — opens at 200°F to shut down furnace operation upon detecting abnormal flame rollout
• Acts as a primary safety cutout to protect the heat exchanger, burner box, and surrounding components
• Designed for use in Nordyne-family furnaces including brands such as Frigidaire, Gibson, Tappan, Westinghouse, and others under the Nordyne umbrella
• Helps maintain safe, code-compliant furnace operation
• Durable construction for long-term reliability in demanding heating environments

Application

This flame rollout switch is a direct OEM replacement for compatible Nordyne furnace models. It is installed near the burner compartment and serves as a thermal safety device. When flame rollout is detected — typically caused by a cracked heat exchanger, blocked flue, or restricted airflow — the switch opens the control circuit, shutting down the burner to prevent further damage or safety hazards.
