Goodman 0130F00038 Auxiliary Limit Switch (Light Blue)

The Goodman 0130F00038 is the color-coded light-blue auxiliary limit switch for the WFD18115S5CXCB furnace and compatible models. As a secondary thermal safety, it backs up the primary limit — opening the control circuit and shutting off the gas valve if temperatures climb beyond a safe range in its monitored zone. The light-blue code identifies its specific factory trip temperature so it isn't confused with the primary (pink) limit.

Specifications

Part Number: 0130F00038
Category: Limit Switch — auxiliary / secondary high limit
Color Code: Light Blue (denotes factory-set trip temperature)
Operation: Normally closed, opens on overtemperature
Fits: Goodman WFD18115S5CXCB and compatible furnaces

OEM vs. Generic

Auxiliary limits are safety devices set to an exact temperature — the light-blue color code exists precisely so the correct switch goes back in. The OEM Goodman part ships with the right set point and mounting geometry. Substituting an unmatched generic switch risks either nuisance shutdowns or a compromised safety chain. Always match the OEM part number, not just the color.

Installation Difficulty

Easy. Mounts with two screws and two spade connectors. De-energize the furnace, transfer wiring one lead at a time, and reinstall. Roughly a 10-minute job.
