The Goodman B1370145 300°F Rollout Switch is a genuine OEM manual-reset flame rollout safety for Goodman/Amana AMS80904BNA gas furnaces. Mounted on the burner box, it opens and shuts off the gas valve if flame rolls out of the heat exchanger — a critical safety device that protects against blocked heat exchangers and improper combustion. A tripped or failed rollout switch will prevent the furnace from firing until the fault is corrected and the switch is reset.

  • Part number: B1370145
  • Trip temperature: 300°F (opens on rise)
  • Reset type: Manual reset
  • Function: Flame rollout safety limit
  • Fits: Goodman/Amana AMS80904BNA and compatible furnace models

OEM vs. Generic: Safety limits must trip at the exact rated temperature. This OEM switch is calibrated to Goodman's 300°F spec; a mismatched generic can trip late and defeat the protection it provides. For a life-safety component, always use OEM.

Install difficulty: Easy (2/5). Cut power, unclip the two spade terminals, unscrew the switch, and mount the replacement. Basic hand tools; 15 minutes. If it keeps tripping, diagnose the root cause before returning to service.
