The Goodman 10123529 Manual Reset Limit Switch is a genuine OEM high-temperature safety control for the ACEC801005CXAB gas furnace. It opens the control circuit and shuts off the burners if it detects an over-temperature or flame-rollout condition, then requires a manual press to reset — by design, so a technician inspects the cause before the furnace fires again. A tripping or failed switch is a frequent cause of a furnace that ignites then immediately shuts down.

Specifications

OEM Part Number: 10123529
Type: Manual reset thermal limit / rollout switch
Function: Normally closed, opens on over-temperature
Reset: Manual push-button
Compatibility: Goodman ACEC801005CXAB and related furnace models

OEM vs. Generic

OEM 10123529 switches are calibrated to the exact trip temperature specified for this furnace and use matching terminal and bracket dimensions. A generic switch with the wrong trip point either nuisance-trips or — worse — fails to protect against a genuine over-temp event. For a safety device, always choose OEM.

Install Difficulty

Easy (1/5). Disconnect power, unplug the two spade terminals, remove two mounting screws, and install the replacement. Important: a repeatedly tripping limit indicates an underlying problem (dirty filter, blocked vent, failing blower) — diagnose the root cause, don't just reset.
