The Amana-Goodman 10123538 Limit Switch is a critical OEM safety component engineered for high-temperature monitoring in residential and light commercial HVAC systems. This 230F manual reset limit switch functions as a primary safety cutout, interrupting the burner circuit if heat exchanger temperatures exceed the 230-degree Fahrenheit threshold. Built to rigorous factory specifications, this Goodman furnace limit switch ensures precise thermal response and long-term reliability in demanding cycles. As a genuine HVAC high-limit safety switch, it maintains the integrity of the furnace control board's safety string. It serves as a direct OEM replacement part for a wide array of equipment from brands including Goodman, Amana, Daikin, Kenmore, McQuay, Xenon, GMC, and Gree. Technical precision in the bimetallic sensing element ensures accurate nuisance-trip prevention while providing essential over-temperature protection. Proper installation involves verifying the mounting footprint and ensuring the 10123538 heating element limit is positioned for optimal airflow sensing within the plenum. OEM Compatibility: Guaranteed fit for Amana, Goodman, and Daikin systems, adhering to original manufacturer tolerances. Manual Reset Functionality: Provides a critical diagnostic checkpoint, requiring a technician to inspect the system before restarting the burner. High-Temperature Calibration: Pre-set at 230°F for accurate thermal protection of the heat exchanger. Durable Construction: Engineered to withstand the rigors of high-cycle frequency in modern high-efficiency furnaces. Direct Factory Replacement: Eliminates the risks associated with universal or aftermarket components that may drift in thermal sensitivity. Common Technical Questions How do I know if my 10123538 limit switch is tripped? If the furnace blower runs continuously but the burners fail to ignite, check the manual reset button on the back of the switch. Continuity testing with a multimeter will confirm if the internal contacts remain open. Is this switch compatible with multi-stage Goodman furnaces? Yes, the Amana-Goodman 10123538 is utilized across various single-stage and multi-stage platforms; however, always verify the temperature rating on the existing switch plate before installation. Can I use a 230F switch to replace a 200F limit? No. Safety limits must always match the manufacturer’s specified temperature rating to prevent heat exchanger damage or fire hazards.
