Goodman 10123529 Manual Reset Limit Switch

The Goodman 10123529 is a genuine OEM manual-reset high-limit / flame-rollout safety switch engineered for the WFM18115S5CXCB gas furnace and compatible Goodman and Amana models. This normally-closed thermal switch opens the ignition control circuit if it senses abnormally high temperature or a flame-rollout condition, shutting down the burners to prevent overheating and unsafe operation. Because it is a manual-reset design, a tripped switch must be reset by hand after the underlying fault is corrected — an intentional safeguard that flags a real problem for service.

Function: Manual-reset high-limit / rollout safety cutout
Configuration: Normally closed (opens on over-temperature)
Reset: Push-button manual reset
Fits: Goodman/Amana furnaces including WFM18115S5CXCB
Type: Direct-fit OEM replacement

OEM vs. Generic

This is the authentic Goodman OEM part, calibrated to the exact trip temperature the furnace was designed around. Generic aftermarket switches may carry a slightly different set-point or bracket geometry, which can cause nuisance trips or improper safety response. For a safety-critical component we strongly recommend genuine OEM.

Installation Difficulty

Easy (1 of 3). Shut off power and gas, disconnect the two spade terminals, remove the mounting screws, and swap in the new switch. Basic hand tools and 10–15 minutes for most technicians. If the switch keeps tripping, diagnose the root cause (blocked flue, dirty burners, cracked heat exchanger) before returning the furnace to service.
