The Goodman 10123529 Manual Reset Limit Switch is a genuine OEM high-limit / rollout safety control designed for the Goodman ACEC800603AXAA gas furnace and compatible Goodman/Amana models. When excessive heat or a flame-rollout condition is detected, this switch opens the control circuit to shut down the burner, protecting the heat exchanger and your home. Because it is a manual reset device, it must be physically reset after a trip — which is exactly what makes it a reliable last line of defense against repeat fault conditions.

  • Type: Manual reset, normally-closed limit / rollout switch
  • Function: High-temperature furnace safety cutoff
  • Terminals: 1/4 in. quick-connect spade
  • OEM Part #: 10123529
  • Fits: Goodman ACEC800603AXAA and select Goodman/Amana gas furnaces

OEM vs. Generic: Our genuine OEM 10123529 is calibrated to the exact factory trip temperature for this furnace family, ensuring correct safety response and warranty compliance. Aftermarket generics may use a different trip point or looser tolerance, which can cause nuisance trips or — worse — fail to protect the heat exchanger. For a safety control, OEM is the recommended choice.

Installation difficulty: Easy (★★☆☆☆). Disconnect furnace power, remove the two mounting screws, transfer the spade connectors, and re-mount. Most DIYers complete this in 15–20 minutes. If the switch keeps tripping after replacement, have a technician inspect airflow and the heat exchanger.
