The Goodman B1370145 is a genuine OEM 300°F flame rollout limit switch for the Amana/Goodman AMH80703ANAA gas furnace and compatible models. This manual-reset safety device is mounted near the burner box and instantly cuts power to the gas valve if flame rolls out of the burner compartment — a critical protection against a blocked heat exchanger or restricted venting. If your furnace has locked out and the button won't reset, or the switch is open at room temperature, replacement is required.

  • Trip temperature: 300°F
  • Type: Manual-reset flame rollout safety limit
  • Function: De-energizes the gas valve on detected flame rollout
  • Fit: OEM replacement for Goodman/Amana AMH80703ANAA furnaces
  • Part number: B1370145

OEM vs. Generic: Safety limits must trip at the exact rated temperature. The OEM B1370145 is calibrated to Goodman's specification; a mismatched generic can trip too late (defeating the safety purpose) or too early (causing nuisance lockouts). On a life-safety device this inexpensive, OEM is strongly recommended.

Install difficulty: Easy (DIY-friendly). Shut off power and gas, disconnect the two spade terminals, remove the mounting screws, and install the replacement. Always diagnose and correct the root cause (dirty burners, cracked heat exchanger, or venting problem) before returning the furnace to service.
