Description
The Goodman B1370165 is an OEM replacement rollout switch designed to protect furnaces from the hazards of flame rollout. When burner flames extend beyond their intended path — due to a blocked heat exchanger, restricted flue, or other combustion issues — this safety device responds immediately, cutting power to the burner circuit before damage or injury can occur.
How It Works
This switch operates on a Single-Pole, Single-Throw (SPST) configuration and is set to trip at 250°F. Once the rollout condition is detected and the switch opens, it must be manually reset — a deliberate design feature that requires a technician to inspect and correct the root cause before the system can be returned to operation. This prevents the furnace from automatically restarting into an unsafe condition.

Why Manual Reset Matters
Unlike automatic-reset limit switches, a manual reset rollout switch ensures that a qualified HVAC technician diagnoses and resolves the underlying combustion issue before the system is restarted. This is a critical safety distinction that protects equipment, property, and occupants.
