Positioned near the blower or secondary heat exchanger, this auxiliary limit provides an additional layer of overheat protection beyond the primary limit — opening the control circuit and shutting off the gas valve if it detects abnormal heat buildup, typically from restricted return airflow or a stalled blower. The color code (light blue) identifies its specific factory trip temperature, so matching the exact part is essential.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 0130F00038\u003c\/li\u003e\n\u003cli\u003eComponent Type: Auxiliary \/ secondary limit switch\u003c\/li\u003e\n\u003cli\u003eColor Code: Light blue (trip-temperature identifier)\u003c\/li\u003e\n\u003cli\u003eAction: Normally closed, opens on over-temperature\u003c\/li\u003e\n\u003cli\u003eCompatible Model: AMVM970603BNAA (Amana \/ Goodman furnace)\u003c\/li\u003e\n\u003cli\u003eFit: Direct OEM replacement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe light-blue color code exists precisely because trip temperature matters.
