OEM Goodman B1370145 300°F Flame Rollout Switch

This genuine OEM flame rollout limit switch, rated to open at 300°F, is a critical safety component on the Goodman / Amana AMH81405DXAA gas furnace. Mounted near the burner assembly, the rollout switch senses flame or heat escaping outside the combustion chamber — a sign of blocked venting, a cracked heat exchanger, or a plugged flue — and shuts off the gas valve to prevent a dangerous condition. A tripped or failed switch will lock out the furnace on a no-heat call. Never bypass this safety device.

Specifications

OEM Part Number: B1370145
Open Temperature: 300°F
Reset: Manual push-button reset
Application: Amana/Goodman AMH81405DXAA furnace
Function: Flame rollout combustion safety cutoff
Type: Genuine OEM replacement

OEM vs. Generic

The OEM B1370145 is factory-calibrated to the exact 300°F trip point and terminal/mount pattern the AMH81405DXAA requires. A generic switch with a different set-point or reset style can trip prematurely or, worse, fail to trip when it should. For a life-safety limit, only an exact-spec OEM part is acceptable.

Install Difficulty

Easy (2 of 5). Shut off power and gas, note wire positions, unscrew the switch from the burner bracket, transfer the terminals, and mount the new switch flush. About 15–20 minutes. If the switch tripped, diagnose and correct the root cause (venting, heat exchanger, airflow) before returning the furnace to service.
