This secondary thermal safety control provides overheat protection at a specific zone of the furnace (blower or heat-exchanger area). If temperatures exceed its rated trip point, it opens the control circuit to prevent damage. A tripped or open auxiliary limit is a frequent reason a furnace won't fire or repeatedly shuts down mid-cycle.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Auxiliary \/ secondary high-limit switch\u003c\/li\u003e\n\u003cli\u003eColor code: Light blue (factory identifier for trip rating)\u003c\/li\u003e\n\u003cli\u003eConfiguration: Normally closed, opens on over-temperature\u003c\/li\u003e\n\u003cli\u003eFitment: Goodman\/Amana AMES921004CNAA and compatible 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\u003eBecause the \u003cstrong\u003elight-blue color code\u003c\/strong\u003e corresponds to a precise trip temperature, the \u003cstrong\u003eOEM 0130F00038\u003c\/strong\u003e is strongly recommended to ensure the correct safety threshold.
