Goodman 10123517 Manual Reset Limit Switch

The genuine Goodman 10123517 manual reset limit switch is a direct-fit safety control for the GMH950905CXAC 96% AFUE gas furnace. This high-temperature cutoff opens the control circuit if it senses flame rollout or excessive heat at the burner box, immediately stopping the furnace to protect against fire and heat-exchanger damage. Because it is a manual reset device, it stays open after a trip and requires a physical button press — a deliberate design that forces a technician to inspect the cause before the furnace can run again.

Specifications

OEM Part Number: 10123517
Compatible Model: GMH950905CXAC
Type: Manual reset thermal limit / flame rollout switch
Reset: Push-button manual reset (does not auto-reset)
Equipment Type: Gas Furnace

OEM vs. Generic

Rollout and manual-reset limits are trip-temperature specific and must match the burner assembly. A mismatched generic switch can nuisance-trip or fail to protect at the correct threshold. This OEM part guarantees the factory trip point, bracket, and terminal layout.

Installation Difficulty

Easy (1/5). Two screws and two spade terminals. Cut power first, and if the switch tripped, diagnose the rollout cause before resetting or replacing.
