It monitors temperature in the blower or heat-exchanger area and opens the circuit to shut off the burners if the furnace overheats — protecting the heat exchanger and cabinet from heat damage caused by restricted airflow, a dirty filter, or blower failure. A tripped or open auxiliary limit is a common reason a furnace stops heating.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Number:\u003c\/strong\u003e 0130F00038\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Auxiliary \/ rollout safety limit switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIdentifier:\u003c\/strong\u003e Light-blue body (temperature-rated per OEM spec)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Normally closed; opens on over-temperature\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Goodman (genuine OEM)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e GCH91155DXAC and compatible Goodman \/ Amana furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eLimit switches are color- and temperature-coded — installing the wrong trip point (a generic or mismatched switch) either nuisance-trips or, worse, fails to protect the furnace.
