The Goodman 0130F00036 is a genuine OEM high-limit safety switch engineered for the GDH80403AXBD gas furnace and other compatible Goodman/Amana 80% AFUE models. Identified by its pink marking, this limit control monitors heat-exchanger and plenum temperature, opening the circuit to shut down the burners if the furnace overheats. It is a critical safety component — a failed or drifting limit switch is a common cause of nuisance lockouts, short cycling, and no-heat calls.
This is a factory OEM Goodman part, not an aftermarket clone. OEM limit switches are calibrated to the exact trip temperature specified for your furnace, ensuring correct safety cutout and full warranty compatibility. Generic universal limits often carry looser temperature tolerances and can cause premature or delayed tripping. For a safety control, exact-fit OEM is strongly recommended.
Rating: Easy (2/5). Replacement typically takes 15–20 minutes with basic hand tools. Always disconnect power at the furnace switch and breaker before servicing. If the switch continues to trip after replacement, consult a licensed HVAC technician, as repeated limit trips can indicate airflow restriction or heat-exchanger issues.
Restore safe, reliable furnace operation with a genuine Goodman replacement limit switch.
