The Goodman 0130F00038 Auxiliary Limit Switch is a genuine OEM secondary safety control for the WFM18045S3AXCB modular blower furnace and compatible Goodman/Amana models. Marked by its light blue housing, this auxiliary limit provides backup overheat protection, opening the control circuit if temperatures in its zone exceed the safe threshold — a critical second line of defense alongside the primary limit.

  • Part number: 0130F00038
  • Function: Auxiliary / secondary high-limit cutout
  • Color code: Light blue
  • Fit: WFM18045S3AXCB and compatible Goodman furnaces
  • Type: Snap-disc thermal switch

OEM vs. Generic: The OEM 0130F00038 matches Goodman's exact temperature rating and terminal layout for a plug-and-play fit. Generic substitutes may look similar but often carry different trip points, risking nuisance lockouts or reduced protection. At this price, there's no reason to gamble with a generic on a safety device.

Install difficulty: Easy — a quick swap with two screws and push-on terminals. Cut power and gas first. Under 15 minutes for most homeowners and any HVAC tech.
