The Goodman 10123533 Manual Reset Limit Switch is a genuine OEM high-limit safety control for the GKS90905DXAE gas furnace and compatible GKS90 series models. It monitors heat-exchanger and plenum temperature and opens the circuit to shut off the burner if the furnace overheats — for example due to a blocked filter, failed blower, or restricted airflow. The manual-reset design requires a deliberate reset, prompting an inspection before the furnace can fire again after a trip.

Specifications

OEM Part Number: 10123533
Category: Limit Switch (High-Limit, Manual Reset)
Compatible Model: GKS90905DXAE (and related GKS90 series)
Type: Temperature-actuated safety switch, manual reset button
Function: Overheat / high-limit burner shutoff

OEM vs. Generic

This genuine OEM switch is calibrated to the precise trip temperature Goodman specifies for this furnace. A generic switch with a different setpoint can trip prematurely (nuisance no-heat) or, worse, fail to trip when it should — defeating a critical safety function. For a safety control, matching the OEM temperature rating is non-negotiable.

Installation Difficulty

Moderate (3/5). Shut off power and gas, remove the two mounting screws, transfer the wiring to the identical terminals, and confirm the switch seats flat against the mounting surface. Because this is a safety device, verify correct operation after installation and, if in doubt, have a licensed HVAC technician confirm the furnace's high-limit protection is working.
