Protect your Goodman ADSS800804BXAD furnace from overheating with this genuine OEM limit switch, identified by its pink temperature-code marking. This high-limit safety control senses air temperature in the heat exchanger area and interrupts the gas valve if the furnace exceeds its safe operating temperature — guarding against restricted airflow, dirty filters, and blower failures that could crack the heat exchanger.
The pink code identifies a specific trip and reset temperature calibrated for this furnace. Our OEM Goodman switch matches that spec exactly, preventing the nuisance trips or delayed protection that come with mismatched aftermarket switches. For a safety control, installing the correct OEM temperature rating is essential — never substitute a different color code.
Easy (1/5). Cut power to the furnace, disconnect the two spade terminals, remove the mounting screws, and install the new switch. About 10–15 minutes with a nut driver. Before returning the furnace to service, check the filter and blower to correct whatever airflow restriction may have caused the original limit trip.
