This auxiliary switch acts as a backup high-limit control, monitoring a secondary zone of the furnace and de-energizing the gas valve if temperatures exceed safe thresholds. It provides an extra layer of overheat protection beyond the primary limit and is essential for safe, code-compliant furnace operation.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 0130F00038\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Auxiliary \/ secondary high-limit safety switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor Code:\u003c\/strong\u003e Light blue (temperature-rated)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Goodman \/ Amana\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e ACES800603AXAA furnace\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Backup over-temperature shutoff\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003egenuine OEM Goodman\u003c\/strong\u003e auxiliary switch is factory-calibrated to the precise temperature setpoint specified for this furnace's safety circuit.
