The Goodman 10123529 is a genuine OEM manual reset high-limit switch for ACVC800803BXAA gas furnaces and compatible models. This safety control opens the burner circuit if the furnace overheats — protecting the heat exchanger from damage caused by restricted airflow, a dirty filter, or blower failure. A manual reset design requires the technician to physically reset the button, ensuring the underlying cause is addressed before the furnace fires again.
The genuine Goodman OEM switch is factory-calibrated to the correct trip temperature for this furnace model. Generic substitutes with the wrong trip point can nuisance-trip or, worse, fail to protect the heat exchanger. As a safety component, OEM is strongly recommended.
Easy (2/5). About 15–20 minutes for a qualified technician. Cut power, disconnect the two spade terminals, remove the mounting screws, install the replacement, and confirm correct operation. Investigate the airflow restriction that caused the trip before returning to service.
