The Goodman 0130F00038 Auxiliary Limit Switch (Light Blue) is a genuine OEM thermal safety control for the WFD18090S4BXCB gas furnace. The light-blue color code identifies its specific trip temperature. As an auxiliary limit, it provides secondary overheat protection — typically monitoring the blower compartment or a secondary section of the heat exchanger — and opens the control circuit to stop the burners if temperatures exceed safe limits.

Specifications

Part Number: 0130F00038
Type: Auxiliary High-Limit Thermal Switch
Color Code: Light Blue (denotes specific trip temperature)
Function: Secondary overheat / rollout safety cutoff
Brand: Goodman (fits Amana)
Fits Model: WFD18090S4BXCB and compatible Goodman/Amana furnaces

OEM vs. Generic

Like the primary limit, this auxiliary switch is factory-calibrated — the light-blue code marks its exact rating. Substituting an incorrectly rated generic switch defeats the safety design. Match the OEM 0130F00038 by both part number and color code to ensure the furnace's safety chain functions as engineered.

Installation Difficulty

Easy (1 of 5). Disconnect power, remove the mounting screws, transfer the spade terminals, and reinstall the new switch in the same position and orientation. Test a full heat cycle to confirm normal operation before closing the cabinet.
