The Goodman B1370145 Rollout Limit Switch is a genuine OEM 300°F manual-reset safety switch for the Amana/Goodman AMV80905CXBA gas furnace. Mounted on the burner box, the rollout switch detects abnormal flame rollout or excessive heat outside the heat exchanger and immediately cuts power to the gas valve, preventing unsafe operation. A tripped or failed rollout switch stops the furnace from firing — this exact-fit replacement restores critical flame-safety protection.

Specifications

OEM Part Number: B1370145
Trip Temperature: 300°F (manual reset)
Compatible Model: AMV80905CXBA
Function: Flame rollout / high-temperature safety cutout
Type: Normally closed, manual-reset limit switch
Brand: Goodman (Amana compatible)

OEM vs. Generic

The OEM B1370145 is calibrated to the exact 300°F trip point and bracket footprint the furnace requires. Substituting a switch with a different temperature rating or mounting can defeat the safety function or cause nuisance trips. Because this is a life-safety component, the factory OEM part is strongly recommended.

Installation Difficulty: Easy

A 15-minute repair. Turn off power and gas, remove the burner-compartment door, disconnect the two spade terminals, remove the mounting screws, and install the new switch. Important: if a rollout switch trips repeatedly, have a technician diagnose the underlying cause (blocked flue or cracked heat exchanger) before returning the furnace to service.
