The Goodman 10123538 Manual Reset Limit Switch is a genuine OEM high-temperature safety control for the Goodman ACEC960603BNAB. It monitors heat-exchanger/burner temperature and opens the circuit to shut down the burner if the unit overheats — a critical flame-rollout and over-temp protection. Unlike auto-reset limits, this manual-reset switch requires a physical button press to restore operation, ensuring a technician inspects the cause before the furnace fires again.

OEM Part Number: 10123538
Brand: Goodman
Compatible Model: ACEC960603BNAB
Type: Manual reset high-limit / rollout switch
Function: Over-temperature burner shutoff safety
Fit Type: Direct OEM replacement

OEM vs. Generic: Safety limits must trip at the factory-specified temperature. The OEM 10123538 is calibrated to Goodman's exact trip point for the ACEC960603 heat exchanger. A generic switch with the wrong setpoint can nuisance-trip or, worse, fail to protect against a genuine overheat. Always use the OEM-spec part for safety controls.

Install Difficulty: Easy–Moderate (2/5). Disconnect power and gas, unplug the two terminals, remove the mounting screws, install the new switch, and reconnect. About 15–20 minutes. If the original tripped, diagnose the airflow/heat-exchanger cause before returning to service.
