The Goodman 10123519 Manual Reset Limit Switch is a genuine OEM safety control for GCH90904CXAB gas furnaces. This thermal switch monitors heat exchanger and burner temperatures and opens the circuit to shut down the furnace if it overheats or experiences flame rollout. Unlike an auto-reset limit, this manual-reset design stays open until the red button is physically pressed, forcing an inspection before the furnace can restart — a deliberate safety feature that flags airflow or combustion problems.

Specifications

OEM Part Number: 10123519
Part Type: Manual reset high-limit / rollout safety switch
Brand: Goodman
Equipment: Gas furnace
Compatible Model: GCH90904CXAB
Reset Type: Manual (push-button)

OEM vs. Generic

The genuine 10123519 is calibrated to the exact trip temperature and bracket footprint your furnace's safety circuit requires. A generic switch with the wrong setpoint can trip too early (nuisance no-heat) or too late (unsafe overheating). Because this is a life-safety component, always use the factory-specified OEM limit switch — never bypass or jump it out.

Installation Difficulty

Easy (2/5). About a 15-minute job. Turn off power and gas, note wire positions, remove the mounting screws, transfer the two spade terminals to the new switch, and reinstall. After replacing, diagnose why the original tripped — restricted airflow, a dirty filter, or a cracked heat exchanger — before returning the furnace to service.

Safety note: If this switch keeps tripping, stop and have a qualified technician inspect the furnace. Confirm your model is GCH90904CXAB. Email info@nationalhvacparts.com for fitment help.
