Goodman 10123538 Manual Reset Limit Switch

The Goodman 10123538 is a factory-original manual reset high-limit switch for the AMES920403ANAA gas furnace. This safety control monitors heat-exchanger temperature and opens the circuit to shut down the burners if the furnace overheats — protecting against fire and heat-exchanger damage. Its manual reset button ensures the unit will not automatically restart after a trip, so the underlying cause (blocked airflow, failed blower, dirty filter) is investigated before the furnace runs again.

Specifications

OEM Part Number: 10123538
Part Type: Manual reset high-limit switch
Function: Over-temperature safety cutout
Brand: Goodman / Amana
Compatible Equipment: AMES920403ANAA gas furnace
Fit: Exact OEM replacement

OEM vs. Generic

The genuine Goodman 10123538 is calibrated to the exact trip temperature specified for the AMES920403ANAA. Because this is a life-safety component, using the correctly rated OEM switch is critical — a generic switch with the wrong trip point can either nuisance-trip or, worse, fail to protect the furnace. Do not substitute an auto-reset switch for this manual-reset control.

Installation Difficulty

Easy to Moderate. Typically a two-screw, two-wire swap on the burner box; 15–20 minutes with basic tools. Turn off power and gas before servicing. After replacement, diagnose why the limit tripped before returning the furnace to service.
