The Goodman 10123533 Manual Reset Limit Switch is a genuine OEM high-temperature safety cutout for the GKS90904CXAD gas furnace. This switch monitors heat-exchanger and cabinet temperature and opens the burner circuit if the furnace overheats — a critical safety device that prevents heat-exchanger damage and cracked-exchanger CO risk. Because it is a manual reset, a tripped switch signals an underlying airflow or overheating fault that should be diagnosed before pressing reset.

OEM vs. Generic

This OEM Goodman switch is calibrated to the exact trip and reset temperatures specified for your furnace's heat exchanger. Generic limit switches with the wrong setpoint can nuisance-trip or, worse, fail to protect the exchanger. OEM ensures the correct calibration and mounting bracket footprint.

Installation Difficulty

Easy–Moderate (2/5). Disconnect furnace power, note the two wire positions, unscrew the mounting bracket, and swap in the new switch. Basic multimeter continuity testing is helpful for confirming the fault. Restore power and cycle the furnace to verify.

Also fits many Goodman GKS90 series cabinets. Contact info@nationalhvacparts.com to confirm.
