The Goodman 0130F00038 Auxiliary Limit Switch (Light Blue) is a genuine OEM safety control for the Goodman/Amana AMVC80805CNBA gas furnace. This normally-closed thermal switch opens the control circuit if temperatures in the blower or burner area exceed its rated trip point, protecting the heat exchanger and surrounding components from overheating. The light-blue body denotes its specific temperature calibration — using the correct color-coded switch is critical for proper safety operation.
The OEM 0130F00038 matches Goodman's exact trip and reset temperatures, mounting footprint, and terminal orientation. Because a limit switch is a life-safety device, substituting a generic switch with a different calibration can cause either nuisance lockouts or, worse, failure to protect against overheating. Always match the OEM color code.
Easy (1 of 5). De-energize the furnace, note wire positions, remove two mounting screws, transfer the spade connectors, and secure the new switch. No adjustment needed. Replacement typically takes 10–15 minutes. Verify a normal heat cycle and confirm the switch does not trip under standard operation.
