The Goodman B1370145 Rollout Limit Switch is a genuine OEM flame-rollout safety control engineered for the Goodman/Amana AMS80703ANAA gas furnace. This manual-reset switch trips at 300°F to shut off the gas valve if burner flames roll out of the combustion chamber — a critical safety function that protects the heat exchanger, blower compartment, and your home from overheating and combustion hazards.

Specifications

Trip temperature: 300°F (open on rise)
Reset type: Manual push-button reset
Function: Flame rollout / burner safety cutoff
Fits model: AMS80703ANAA and compatible 80% AFUE Goodman/Amana furnaces
OEM Part Number: B1370145

OEM vs. Generic

Our OEM Goodman switch is calibrated to the exact factory trip point and mounting footprint, guaranteeing correct clearance and reliable safety response. Universal generic rollout switches may vary in trip tolerance and bracket dimensions — for a safety-critical control, factory-spec OEM is strongly recommended.

Installation Difficulty

Easy (1/5). A basic replacement: disconnect power, unplug the two spade terminals, unscrew the bracket, and mount the new switch in the same orientation. Takes about 10 minutes with a nut driver. Always confirm the root cause of a rollout trip before resetting or replacing.
