The Goodman 0130F00038 is a genuine OEM auxiliary limit switch, identified by its light-blue housing, engineered as an exact-fit replacement for the Amana/Goodman AMH81405DXCB gas furnace and compatible models. This secondary safety device supplements the primary limit, opening the circuit if a specific zone of the furnace exceeds its safe temperature — guarding against overheating from blower or airflow problems.
The light-blue color code corresponds to a specific factory trip temperature. Installing a genuine OEM switch guarantees the correct calibration — critical for a safety component. Mismatched generics may trip early (nuisance shutdowns) or too late (inadequate protection). Always match OEM.
Easy (2/5) — Generally a two-screw, two-terminal replacement. Cut power and gas before servicing and confirm the correct color-coded part before installing. Simple enough for a confident DIYer.
