Goodman 10123529 Manual Reset Limit Switch

The Goodman 10123529 is a manual-reset high-limit safety switch engineered as a direct OEM fit for the Amana/Goodman WFM18070S3AXCB gas furnace and compatible models. This snap-disc control monitors heat-exchanger and plenum temperature, opening the burner circuit if the furnace overheats due to restricted airflow, a failed blower, or a dirty filter. Because it is a manual-reset design, it will not auto-cycle after a fault — protecting your equipment and prompting inspection before the furnace is allowed to fire again.

Specifications

Type: Manual reset high-limit / rollout safety switch
Function: Opens burner circuit on over-temperature
OEM Part Number: 10123529
Fits: WFM18070S3AXCB and compatible Goodman/Amana furnaces

OEM vs. Generic

The genuine OEM 10123529 is calibrated to the exact trip and reset temperatures Goodman engineered for this furnace, ensuring proper safety response. Generic aftermarket switches may differ in trip point, bracket geometry, or terminal orientation, risking nuisance lockouts or improper protection. For a safety-critical component, OEM is strongly recommended.

Installation Difficulty

Easy (1/5). Two-wire, plug-and-play replacement — disconnect power, remove the two mounting screws and spade terminals, and swap. Roughly 10–15 minutes for a homeowner comfortable with basic HVAC service. Always shut off power and gas before servicing.
