Goodman B1370145 300°F Flame Rollout Switch

The B1370145 is a genuine OEM 300°F manual-reset flame rollout switch for the Goodman GMV80905CXA gas furnace. It is a critical safety limit mounted near the burner box that trips and cuts gas to the valve if flame rolls out of the burners — a condition usually caused by a blocked heat exchanger, cracked exchanger, or poor combustion airflow. When this switch opens, the furnace locks out and will not fire until the fault is corrected and the button is reset.

Trip temperature: 300°F
Function: Manual-reset flame rollout safety limit
Fits model: Goodman GMV80905CXA (verify against your rating plate)
Type: OEM factory safety switch
Brand: Goodman

OEM vs. Generic

Because this is a life-safety component, the OEM B1370145 is calibrated to Goodman's exact 300°F trip point and terminal layout. Generic rollout switches with the wrong trip temperature can either nuisance-trip or, worse, fail to protect against a genuine rollout event. Always use the factory-specified switch on safety circuits.

Install Difficulty

Easy to moderate. Disconnect power, unplug the two spade terminals, and unscrew the switch from the burner assembly. Never bypass or jump a tripped rollout switch — if it keeps tripping, diagnose the heat exchanger and combustion airflow before returning the furnace to service.
