The genuine Goodman 10123529 manual reset limit switch is the OEM high-temperature safety control for the ACVC81005CXBC gas furnace and compatible Goodman/Amana models. This switch monitors heat exchanger and supply-air temperature; if the furnace overheats — often from restricted airflow or a failed blower — it opens the gas circuit to shut the unit down and must be manually reset, alerting the homeowner to an underlying problem.

Specifications

Part Number: 10123529
Type: Manual reset high-limit switch (rollout/overtemp)
Function: Opens gas valve circuit on overtemperature
Reset: Manual push-button
Fits: Goodman ACVC81005CXBC and compatible furnaces
Electrical: Normally closed, low-voltage control circuit

OEM vs. Generic

OEM limit switches are calibrated to the exact trip temperature specified for your furnace's heat exchanger. A generic switch with the wrong setpoint can either nuisance-trip or, worse, fail to trip when it should — a genuine safety risk. For any safety control, OEM 10123529 is strongly recommended.

Installation Difficulty: Easy

Shut off power and gas. The switch mounts to the burner box or heat exchanger with two screws and connects via two spade terminals. Remove the old switch, transfer the wires, and secure the replacement. After install, press the reset button and verify normal operation. If the switch trips again after reset, diagnose the airflow or combustion issue before continuing.
