Trane SWT04164 Flame Rollout Switch Overview
The Trane SWT04164 is an OEM flame rollout switch designed to protect gas furnaces from hazardous flame rollout conditions. When flames escape the heat exchanger and roll outside their intended combustion path, this safety switch detects the abnormal heat and immediately interrupts the burner circuit — preventing potential fire hazards, heat exchanger damage, and carbon monoxide exposure.
Key Features
- OEM Trane replacement part for precise fit and reliable performance
- Detects dangerous flame rollout conditions and shuts down the burner circuit
- Helps prevent fire hazards, heat exchanger damage, and CO exposure
- Designed for direct drop-in replacement in compatible Trane furnace models
- Ensures continued safe furnace operation and code compliance
What Is a Flame Rollout Switch?
A flame rollout switch is a critical safety device mounted near the burner assembly of a gas furnace. Under normal operation, combustion flames remain contained within the heat exchanger. If a blockage, cracked heat exchanger, or other fault causes flames to roll outward, the rollout switch senses the elevated temperature and opens the circuit — cutting off gas flow to the burners. This prevents equipment damage and protects occupants from fire and carbon monoxide hazards.
Application
- Compatible with select Trane gas furnace models (verify compatibility with your unit’s model number before ordering)
- Ideal for HVAC technicians performing furnace safety inspections, maintenance, or repairs
- Suitable for residential and light commercial Trane furnace applications
