Mounted on the burner assembly, this safety control opens the ignition circuit and shuts down the furnace if flame rolls out of the combustion chamber — protecting your home from overheating and unsafe operation. When your furnace locks out or won't fire, a tripped rollout switch is one of the most common culprits.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eTrip temperature: 300°F (opens on rise)\u003c\/li\u003e\n\u003cli\u003eReset type: Manual push-button reset\u003c\/li\u003e\n\u003cli\u003eCircuit: Normally closed (N.C.)\u003c\/li\u003e\n\u003cli\u003eMount: Burner-box bracket, 1\/4\" quick-connect terminals\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: B1370145\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GMT140-5D and select GMT\/GMP series furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eOur \u003cstrong\u003eOEM Goodman\u003c\/strong\u003e switch is calibrated to the exact 300°F trip point your furnace's safety logic expects, ensuring proper lockout timing and full warranty compliance.
