The Goodman 20162903 Primary Limit Switch (150°F) is a genuine OEM high-limit safety control for the AMSS960403ANAA and compatible Goodman/Amana gas furnaces. Mounted on the heat exchanger or blower deck, it senses supply-air temperature and opens the circuit to the gas valve if the furnace overheats — typically from restricted airflow, a dirty filter, or blower failure.

This is an auto-reset primary limit rated to trip at approximately 150°F. When temperatures return to normal, the switch closes automatically and the furnace resumes. A limit that opens frequently indicates an airflow problem that should be corrected before returning the unit to service.

OEM Goodman part number: 20162903
Type: Primary high-limit switch
Trip temperature: 150°F (approximate)
Reset: Automatic
Function: Over-temperature / airflow safety cutout
Fits: AMSS960403ANAA and compatible 96% gas furnaces
Brands: Goodman, Amana

OEM vs. Generic: The correct trip temperature and insertion depth are critical to safe furnace operation. This OEM switch matches Goodman's exact 150°F calibration and mounting footprint. Generic switches with a different trip point can cause nuisance shutdowns or fail to protect the heat exchanger. OEM is strongly recommended for limit controls.

Install difficulty: Easy (1/5). Cut power to the furnace, unplug the two terminals, remove the mounting screws, and install the replacement in the same orientation. No special tools needed — confirm the airflow issue is resolved before restarting.
