Protect your furnace and home with the genuine OEM Goodman B1370145 flame rollout limit switch, rated to open at 300°F. This is the correct-fit safety control for the Goodman GMV81155CXBA and related Goodman/Amana gas furnaces. Mounted on the burner assembly, the rollout switch is a critical safety device that shuts off the gas valve if flames roll out of the burner box due to a blocked flue, cracked heat exchanger, or failed inducer — preventing dangerous overheating.

OEM vs. Generic

Rollout switches are a life-safety component — an off-spec generic with the wrong trip temperature or reset behavior can nuisance-trip or, worse, fail to protect. This genuine OEM switch is calibrated to Goodman's exact 300°F specification for reliable protection.

Installation Difficulty

Moderate. Shut off power and gas, remove two mounting screws, transfer the spade terminals, and reinstall. If the switch tripped, always diagnose the root cause (blocked flue, weak inducer) before returning the unit to service.
