OEM vs. Generic

The OEM Goodman B1370108 is calibrated to the exact 300°F trip point specified for your furnace, guaranteeing correct fit, terminal orientation, and reliable safety response. Generic equivalents may vary in trip tolerance and reset feel; for a life-safety control we recommend the factory part.
