Goodman 10123529 Manual Reset Limit Switch

The Goodman 10123529 is a manual-reset high-limit / rollout safety switch engineered for the WFM18090S4BXCC gas furnace and compatible Goodman/Amana models. This normally-closed thermal switch trips and stays open when it senses abnormal heat or a flame-rollout condition, cutting power to the gas valve until the fault is corrected and the button is manually reset — a critical safeguard against overheating and unsafe combustion.

Specifications

Type: Manual reset thermal limit / rollout switch
Contacts: Normally closed (opens on over-temp)
Reset: Manual push-button, per OEM trip rating
Terminals: 1/4 in. quick-connect spade
Fit: Goodman WFM18090S4BXCC and cross-compatible furnaces

OEM vs. Generic

This is a genuine Goodman OEM switch built to the factory trip temperature and mounting footprint — no guesswork on calibration. Aftermarket generics may carry a lower up-front price but can differ in trip point and bracket geometry, risking nuisance trips or an improper safety response. For a safety-critical control, OEM is the recommended choice.

Install Difficulty

Easy (2/5). Cut power at the breaker, unplug the two spade terminals, remove the mounting screws, swap in the new switch, and reconnect. Typically a 10–15 minute repair with a nut driver. If the switch keeps tripping after replacement, have the heat exchanger and burners inspected by a licensed technician.
