The Goodman 0130F00038 Auxiliary Limit Switch (light blue) is a genuine OEM safety control for GCH950904CXAE gas furnaces. This thermally activated switch monitors temperature at a secondary location in the furnace and interrupts the burner circuit if it detects an unsafe overheat or rollout condition, protecting the heat exchanger and blower housing from damage.
The light-blue color code identifies this switch's specific trip temperature. Installing the OEM part guarantees the correct rating for the GCH950904CXAE — a mismatched generic switch can trip too early (nuisance no-heat calls) or too late (a genuine safety hazard). Because it is a safety device, matching the factory spec exactly is strongly recommended.
Easy (1/5). Mounts with two screws and two push-on terminals. De-energize the furnace before replacing and confirm the new switch's color/rating matches the original.
