The Goodman B1370145 Flame Rollout Limit Switch is a genuine OEM 300°F manual-reset safety control for the Amana/Goodman AMH80703ANAC gas furnace. Mounted on the burner assembly, this switch shuts off the gas valve if flames roll out of the heat exchanger — a critical safety response to a blocked flue, cracked heat exchanger, or restricted combustion air. If your furnace repeatedly trips on a rollout fault or won't fire, this inexpensive part is a common culprit.

Trip temperature: 300°F (opens on rise)
Reset type: Manual push-button reset
Function: Flame rollout safety cutout
Fit: Goodman/Amana AMH80703ANAC and compatible furnaces
Terminals: 1/4 in. quick-connect spade

OEM vs. Generic: Genuine OEM B1370145 is calibrated to the exact 300°F trip point your furnace's safety circuit requires. Generic switches with mismatched trip temperatures can cause nuisance trips or, worse, fail to protect. For a life-safety component, always fit the OEM-spec part.

Installation difficulty: Easy — a single-fastener swap with two quick-connect wires. About 10 minutes. Turn off power and gas before servicing, and diagnose the root cause of any rollout before returning the unit to service.
