The genuine OEM Goodman 0130F00038 Auxiliary Limit Switch (identified by its light-blue body) is the high-temperature safety cutout for the WFM18140S5DNCC gas furnace. This thermal switch opens the control circuit if it senses an overheat condition — commonly caused by restricted airflow, a dirty filter, or blower failure — protecting the heat exchanger and cabinet from thermal damage. The blue color code corresponds to the factory-set trip temperature for this position.

Specifications

OEM Part Number: 0130F00038
Function: Auxiliary high-limit / overheat safety switch
Color Code: Light blue (factory temperature rating)
Compatible Model: WFM18140S5DNCC (Goodman gas furnace)
Action: Normally closed, opens on over-temperature

OEM vs. Generic

Limit switches are color-coded by trip point, and a mismatched generic switch can either nuisance-trip or fail to protect against a real overheat. Using the correct OEM 0130F00038 guarantees the trip temperature matches the WFM18140S5DNCC design spec — critical for a safety device.

Installation Difficulty

Easy — DIY friendly (2/5). Typically two mounting screws and two push-on terminals. Cut power before servicing. If the new switch trips again, diagnose the underlying airflow problem (filter, blower, ducting) rather than bypassing the switch.
