The Goodman 10123534 Manual Reset Limit Switch is a genuine OEM high-temperature safety control engineered for the Goodman ACSS920804CNAA gas furnace and compatible models. This switch monitors heat-exchanger and plenum temperatures and trips the burners offline if the furnace overheats — a critical protection against blower failures, restricted airflow, and blocked vents. As a manual-reset device, it stays open after a fault until a technician physically presses the reset button, ensuring the underlying problem is investigated before the unit fires again.

Type: Manual reset high-limit safety switch

OEM vs. Generic

This is a genuine Goodman OEM limit switch built to the exact trip temperature and mounting footprint your furnace was designed around. Generic substitutes often carry the wrong cut-out temperature, which can cause nuisance trips or — worse — fail to protect the heat exchanger. For a safety-critical control, OEM is the recommended choice.

Install Difficulty

Easy (DIY-friendly). Disconnect power, remove the two mounting screws, transfer the spade connectors, and reinstall. Most installs take 10–15 minutes with basic hand tools. Always confirm the furnace is fully de-energized before servicing.
