Goodman Amana B1370200 Manual Reset Flame Rollout Limit Switch – Genuine OEM 350°F Green

The Goodman Amana B1370200 Flame Rollout Switch is the ultimate safety "brain" for your furnace’s burner compartment. Distinguished by its Green circular dot, this manual reset limit is designed to detect "flame rollout"—a hazardous condition where flames spill out of the heat exchanger toward the gas valve and wiring. Specifically engineered for Goodman, Amana, and Janitrol furnace series, this sensor acts as a permanent circuit breaker; if temperatures hit 350°F, it "trips" and stays open, requiring a manual intervention to restore power. As a genuine OEM component, it ensures your heating system stays locked out until a technician can verify that the heat exchanger is intact and the venting is clear.

Key Features and Function:

• Critical Safety Integration: Monitors the burner vestibule for excessive heat caused by cracked heat exchangers, clogged flues, or insufficient combustion air.
• Manual Reset Logic: Unlike auto-reset switches, this model features a red center button that must be physically pressed to restore furnace operation, forcing a safety check of the system.
• Genuine OEM Reliability/Fitment: Features the exact small-footprint mounting bracket and high-temperature porcelain insulator required for Goodman burner boxes.
• Color-Coded for Accuracy: The Green dot signifies a specific 350°F trip point, ensuring you don't accidentally install a lower-rated switch that would cause nuisance tripping.

🛠️ HVAC Depot Pro Tip: The "Don't Just Reset" Rule

If you find your furnace is dead and the B1370200 switch has tripped (button is popped up), do not simply press it and walk away. A tripped rollout switch is a major red flag for a blocked exhaust vent or a cracked heat exchanger. During your Diagnostic Check, inspect the burner area for soot or scorched wiring. If the switch trips again shortly after resetting, shut off the gas immediately and have the heat exchanger professionally inspected for safety.
