The Goodman B1370145 is a genuine OEM 300°F flame rollout limit switch designed for the GMNT060-3B gas furnace. This manual-reset safety control monitors the burner area and shuts down the furnace if flames roll out of the combustion chamber — a condition typically caused by a blocked heat exchanger, poor venting, or restricted combustion air. It is a critical safety device that prevents overheating and potential fire hazards.

Specifications

Type: Flame rollout switch (limit control)
Trip temperature: 300°F
Reset: Manual reset
Function: Normally closed, opens on overheat
Compatibility: Goodman GMNT060-3B furnace
OEM Part Number: B1370145

OEM vs. Generic

Genuine OEM switches are calibrated to Goodman's exact 300°F trip point and mounting footprint. Generic switches may trip early (nuisance shutdowns) or late (unsafe operation) and often do not seat correctly in the factory bracket. For a life-safety component, the OEM part is the right choice.

Installation Difficulty

Easy to Moderate. Disconnect power, unplug the two spade terminals, remove the mounting screws, and swap the switch. If the switch tripped, always diagnose the underlying cause (blocked exchanger or venting) before returning the furnace to service.
