The Goodman B1370145 is a genuine OEM 300°F flame-rollout limit switch built as a direct-fit replacement for the GMNTE120-5 gas furnace. A rollout switch is a critical safety control mounted near the burner box: if flames roll out of the combustion chamber — typically from a blocked flue or failing heat exchanger — the switch opens at 300°F and shuts down the gas valve to prevent fire and CO hazards.

Trip point: 300°F open temperature
Reset: Manual reset (button)
Type: Normally-closed flame rollout safety switch
Fits: Goodman GMNTE120-5 furnace
Connection: 1/4 in quick-connect terminals

OEM vs. Generic: This genuine Goodman switch carries the exact 300°F calibration and mounting bracket the furnace was designed around. Generic switches may trip at slightly different temperatures or use different terminal spacing, which can cause nuisance shutdowns or, worse, fail to protect. For a safety control we recommend the OEM part.

Install difficulty: Easy. Turn off power and gas, remove the two spade connectors and mounting screws, swap in the new switch, and reconnect. A repeatedly tripping rollout switch signals an underlying combustion or venting problem — diagnose the root cause before returning the furnace to service.
