Goodman 10123533 Manual Reset Limit Switch

The Goodman 10123533 is a genuine OEM manual reset high-limit safety switch engineered for the AKSS920905DXAA gas furnace and compatible Goodman and Amana models. This safety control monitors heat-exchanger temperature and interrupts the burner circuit when it detects an overheat condition — protecting the furnace and your home from unsafe operation. Because it is a manual reset device, it requires a technician to press the reset button after a fault, which is by design: a trip signals an underlying airflow or venting issue that should be inspected before restarting.

Specifications

Type: High-limit safety switch, manual reset
Function: Opens burner circuit on overheat
Mounting: Furnace heat-exchanger / vestibule panel
Compatibility: Goodman / Amana AKSS920905DXAA and related furnaces
OEM Part Number: 10123533

OEM vs. Generic

Our OEM option is the exact Goodman-specified switch with the correct trip temperature and terminal layout for a true drop-in fit. The Generic equivalent offers the same electrical function at a lower price point and is a solid choice for budget repairs, though trip tolerances may vary slightly from factory spec. For a critical safety limit, most technicians recommend OEM.

Installation Difficulty

Easy (2/5). Disconnect power, remove the burner-compartment door, unplug the two spade terminals, unscrew the switch, and reverse to install. Basic hand tools and 10–15 minutes are typical. Always verify power is off at the breaker before servicing.

If you are unsure which limit switch your furnace uses, confirm the OEM number stamped on the old part before ordering.
