The Goodman 0130F00036 Limit Switch (Pink) is a genuine OEM high-limit safety control for the ACES800603ANAA furnace and compatible Goodman/Amana models. The pink color code identifies its specific temperature rating — limit switches are calibrated to distinct setpoints, so the color/part number must match exactly. This switch monitors heat exchanger temperature and opens the control circuit to shut down the burner if the furnace overheats, protecting against heat-exchanger damage and unsafe operating conditions.
Because the pink code maps to an exact trip temperature, this genuine Goodman OEM switch guarantees the furnace trips at the engineered setpoint. A generic switch with the wrong rating causes nuisance trips or fails to protect the heat exchanger. Always match the OEM part number and color when replacing a limit switch.
Easy (1/5). Two spade-terminal wires and two mounting screws. Cut power before servicing. If the new switch keeps tripping, investigate restricted airflow — clogged filter, closed registers, or a weak blower motor — rather than the switch itself.
