Goodman B1370145 Flame Rollout Limit Switch (300°F)

The genuine OEM Goodman B1370145 is a 300°F manual-reset flame rollout limit switch engineered for the Goodman DMS80905CNA gas furnace and many compatible Goodman/Amana models. Mounted near the burner assembly, this safety device trips and shuts off the gas valve if flame rolls out of the burner box due to a blocked flue, cracked heat exchanger, or restricted combustion air — protecting your equipment and home from overheating.

Specifications

Trip temperature: 300°F
Type: manual-reset flame rollout limit switch
Function: opens gas circuit on flame rollout / overheat
Fits: Goodman DMS80905CNA and compatible furnaces
OEM Part Number: B1370145

OEM vs. Generic

OEM B1370145 is calibrated to the exact 300°F trip point Goodman specifies for this burner design. Generic switches with the wrong setpoint may nuisance-trip or, worse, fail to trip when needed. Because this is a life-safety component, we recommend the genuine OEM part for guaranteed calibration and fit.

Installation Difficulty

Moderate — roughly 15–20 minutes. Shut off gas and electrical power, remove the burner cover, disconnect the two spade terminals, unscrew the switch, and install the replacement in the same orientation. A repeatedly tripping rollout switch indicates an underlying problem (flue blockage or cracked heat exchanger) that a licensed HVAC technician should diagnose before returning the furnace to service.
