OEM Goodman B1370145 Flame Rollout Switch (300°F)

The Goodman B1370145 is a genuine OEM manual-reset flame rollout switch rated to open at 300°F, used on AMH81405DNAC gas furnaces. Mounted on the burner box, it detects flame rollout caused by a blocked heat exchanger or restricted venting and shuts off the gas valve to prevent overheating and fire. It is a critical combustion-safety device and fits both Goodman and Amana furnaces on this platform.

Category: Limit / Rollout Switch
OEM Part Number: B1370145
Trip Temperature: 300°F open
Reset Type: Manual reset
Fits: AMH81405DNAC and compatible Goodman/Amana furnaces

OEM vs. Generic

The genuine OEM B1370145 is calibrated to the exact 300°F trip point and manual-reset action the furnace's safety design requires. Generic switches with different trip temperatures or auto-reset behavior can defeat the intended protection. For a safety limit, always use OEM.

Installation Difficulty

Easy to Moderate — disconnect power, unplug the two spade terminals, and swap the switch on its bracket. Because it is a combustion-safety part, have a technician diagnose why it tripped before replacing.
