This auxiliary limit backs up the primary high-limit, opening the burner circuit if it senses excessive heat in its monitored zone — for example from blocked airflow or a blower fault. The light-blue body color identifies its factory trip calibration, so matching the exact part is important.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Auxiliary \/ secondary limit switch\u003c\/li\u003e\n\u003cli\u003eColor code: Light blue (factory trip calibration)\u003c\/li\u003e\n\u003cli\u003eConfiguration: Normally closed, opens on over-temperature\u003c\/li\u003e\n\u003cli\u003eFunction: Backup heat safety cutout\u003c\/li\u003e\n\u003cli\u003eFits: AMH80904BXCA and compatible Goodman\/Amana furnaces\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: 0130F00038\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe OEM 0130F00038 is color-coded to a specific trip and reset temperature that the AMH80904BXCA design requires. Substituting a differently rated snap-disc — even one that looks identical — can cause nuisance trips or, worse, fail to trip when it should. Because this is a safety device, always match the OEM number and color.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy (1\/5).\u003c\/strong\u003e Disconnect two leads, remove one or two screws, and mount the replacement in the same orientation.
