Description
Lochinvar & A.O. Smith 100208181 280°F Manual Reset Rollout Switch
The Lochinvar & A.O. Smith 100208181 is a 280°F manual reset (M/R) rollout switch designed to protect water heaters and boilers from the dangers of flame rollout. When burner flames escape the combustion chamber and reach the switch, it trips — shutting down the appliance and requiring a manual reset before operation can resume. This fail-safe design ensures that the root cause of rollout is addressed before the unit is restarted, protecting both the equipment and the surrounding structure.
Key Features
- Trip temperature: 280°F (138°C)
- Manual reset (M/R) operation — requires deliberate technician reset after trip event
- Direct OEM replacement for compatible Lochinvar and A.O. Smith appliances
- Designed to detect flame rollout and shut down burner operation immediately
- Helps prevent heat exchanger damage, carbon monoxide hazards, and fire risk
- Compact form factor for easy installation in tight burner compartments
Application
This rollout switch is a genuine OEM replacement part for select Lochinvar and A.O. Smith water heaters and boilers. It mounts near the burner assembly and monitors for abnormal flame rollout conditions. Always verify compatibility with your specific model before installation.
Why Rollout Switches Matter
Flame rollout occurs when combustion gases escape the heat exchanger — often due to a cracked heat exchanger, blocked flue, or excessive gas pressure. A properly functioning rollout switch is a critical safety device that prevents property damage and potential injury. Replacing a faulty or tripped switch with the correct OEM part ensures your system meets original safety specifications.
