The Goodman 0130F00038 Auxiliary Limit Switch (identified by its light-blue housing) is a genuine OEM safety control for the WFM18070S4BXCC furnace and related Goodman/Amana models. This normally-closed thermal switch monitors temperature at a secondary location in the furnace cabinet and opens the control circuit if it senses an overheat condition — typically caused by restricted airflow, a dirty filter, or a failing blower. When it trips, it de-energizes the gas valve to protect the heat exchanger from thermal damage.

OEM Part Number: 0130F00038
Fits Model: WFM18070S4BXCC
Color Code: Light blue
Type: Auxiliary high-limit, normally-closed, auto-reset
Function: Secondary overheat / airflow-failure protection

OEM vs. Generic

The color coding on Goodman limit switches denotes a specific trip temperature — installing the wrong rating will either nuisance-trip during normal heating or fail to protect the furnace. The genuine 0130F00038 guarantees the correct light-blue trip point and mounting footprint. Generic switches rarely match Goodman's exact temperature stamp, making the OEM part the safe pick.

Install Difficulty: Easy

A two-screw swap, about 10 minutes. Power down, note the wire positions, transfer the spade terminals to the new switch, and mount it in the original bracket. No calibration needed.
