The Goodman 10123535 Manual Reset Limit Switch (Red) is a genuine OEM safety switch for the GKS90905DXAC furnace and related Goodman/Amana models. The red-cap color code identifies its specific factory trip temperature, distinguishing it from other manual-reset switches on the same furnace. It shuts off the burners when it senses excessive heat or flame rollout, protecting the heat exchanger and surrounding cabinet from thermal damage.

Specifications

Type: Manual reset limit / flame-rollout switch
Color code: Red (denotes factory trip point)
Reset: Push-button manual reset
Contacts: Normally closed, open on high temp
Fits: Goodman GKS90905DXAC and compatible furnaces
OEM Part #: 10123535

OEM vs. Generic

The red color code exists because trip temperature matters — installing the wrong-rated switch can allow dangerous overheating or cause premature shutdowns. The OEM 10123535 delivers the precise calibration and connector fitment Goodman engineered for this unit. Generic substitutes rarely match the exact rating and are not recommended for safety switches.

Installation Difficulty

Easy (1 of 3). Disconnect furnace power, transfer the two spade connectors, and secure the mounting screw. Confirm you are matching a red-cap switch to a red-cap switch. Because a manual reset means the switch actually tripped, investigate the underlying cause — restricted airflow, flue blockage, or a failing inducer — before returning the furnace to service.
