OEM Goodman 0130F00038 Auxiliary Limit Switch (Light Blue)

The 0130F00038 is a genuine Goodman/Amana auxiliary limit switch — identified by its light-blue body — engineered as a direct-fit replacement for the AMEC800805CNAB gas furnace. This thermally activated safety switch monitors temperature in the blower or burner area and opens the control circuit if the furnace overheats, shutting down the gas valve to prevent heat-exchanger damage and fire risk.

Specifications

OEM Part Number: 0130F00038
Component: Auxiliary limit / high-temperature safety switch
Color code: Light blue (denotes trip temperature)
Action: Normally closed, opens on overheat
Compatible Model: AMEC800805CNAB (Goodman/Amana furnace)
Brand: Goodman OEM

OEM vs. Generic

Limit switches are calibrated to a precise trip and reset temperature, indicated here by the light-blue color code. The OEM 0130F00038 guarantees the exact setpoint the furnace was designed around. A generic switch with the wrong temperature rating can cause nuisance shutdowns or, worse, fail to trip when needed — a genuine safety concern. Always match the OEM color and part number.

Installation Difficulty

Easy. With gas and power off, disconnect the two spade terminals, remove the mounting screws, and install the replacement in the same orientation. No wiring changes. Typical time is 10–20 minutes. Confirm normal cycling and that the blower/burner does not overheat after the repair.

Genuine Goodman OEM replacement part. Model fitment verified for AMEC800805CNAB.
