The Goodman 0130F00036 is a genuine OEM auto-reset high-limit switch (identified by its pink calibration marking) for the ADSH800804BXAB gas furnace. This safety control monitors heat-exchanger temperature and interrupts the gas valve circuit if the furnace overheats, then automatically resets once temperatures return to normal. The color code indicates its specific factory trip set point — matching it is essential.
The pink calibration is not cosmetic — it denotes the exact temperature at which this switch opens. An OEM part guarantees the correct trip point for your model. Generic substitutes with the wrong set point can cause nuisance shutdowns or, worse, fail to protect the heat exchanger. Always match by OEM number and color.
Easy (2/5). Two spade terminals and two mounting screws. Cut power and gas before servicing. If the limit keeps tripping, correct the underlying airflow or blower problem rather than repeatedly replacing the switch.
