The Goodman B1370145 is a genuine OEM 300°F flame rollout limit switch for the Goodman/Amana AMH81155CNAA gas furnace and compatible models. Mounted on the burner assembly or manifold bracket, this normally-closed safety device opens the ignition circuit if flame rolls out of the heat exchanger, protecting the cabinet, wiring, and homeowner from an unsafe combustion condition.

A tripped or failed rollout switch typically shows up as a furnace that locks out on a hard fault and will not attempt ignition until the cause is corrected and the switch is reset. If the switch is open or damaged, the furnace stays dead — which is exactly the fail-safe behavior it is designed to provide.

Trip temperature: 300°F
Type: normally-closed flame rollout safety switch (manual reset)
Function: interrupts ignition on flame rollout
Fit: Goodman/Amana AMH81155CNAA and compatible furnaces
OEM part number: B1370145

OEM vs. Generic: Rollout switches are life-safety components, and the trip point must match the furnace design exactly. A generic switch with a slightly different temperature rating or bracket geometry can nuisance-trip or, worse, fail to trip when it should. This genuine Goodman B1370145 is calibrated to the 300°F factory spec and bolts up with no modification.

Install difficulty: Easy to Moderate. Disconnect power, unplug the two spade terminals, remove the mounting screws, install the new switch on the same bracket, and reconnect. Because this is a safety device, always diagnose why it tripped (blocked heat exchanger, cracked exchanger, poor venting) before returning the furnace to service.
