The Goodman 10123529 Manual Reset Limit Switch is the OEM high-temperature safety cutoff for the ACES800403AXAA furnace and compatible Goodman and Amana gas furnaces. This switch opens the control circuit and shuts the burners down if it senses an overheat or flame-rollout condition, then must be manually reset once the fault is cleared. A tripped or failed limit switch is a frequent cause of a furnace that ignites and then drops out on safety.

Specifications

OEM Part Number: 10123529
Type: Manual reset limit / rollout safety switch
Function: High-temperature overheat cutoff
Reset: Manual (push-button)
Brand fit: Goodman / Amana
Primary model: ACES800403AXAA furnace

OEM vs. Generic

The genuine 10123529 is calibrated to the exact trip temperature the furnace was engineered around and uses the correct bracket and terminal layout for a direct plug-in fit. Generic limit switches with the wrong trip point can nuisance-trip or, worse, fail to protect against a real overheat. On a safety device, always use the OEM part.

Install Difficulty

Easy — about 15 minutes. With power off, disconnect the two spade terminals, remove the mounting screws, install the new 10123529 in the same orientation, reconnect, and restore power. A nut driver and a few minutes are all that is needed. If the switch trips again after replacement, have a technician diagnose the underlying overheat cause.
