Goodman 20162903 Primary Limit Switch (150°F)

The Goodman 20162903 is a genuine OEM primary high-limit switch with a 150°F trip rating for the AMS80805CXAD 80% AFUE gas furnace and compatible Goodman/Amana models. Mounted on the heat-exchanger bulkhead, it monitors supply-air temperature and shuts off the burners if the furnace overheats — typically due to restricted airflow, a dirty filter, or blower failure. This auto-reset control restores heating once temperatures return to a safe range.

Specifications

Type: Primary high-limit / auto-reset thermal switch
Trip temperature: 150°F
Function: Opens burner circuit on over-temp
Fits: AMS80805CXAD and related 80% Goodman/Amana furnaces
Terminals: Quick-connect spade
OEM Part: 20162903

OEM vs. Generic

The trip setpoint must match the furnace design. The OEM Goodman 20162903 is calibrated to 150°F exactly as engineered. Generic limits with different setpoints or mounting profiles can cause nuisance lockouts or, worse, fail to protect the heat exchanger. For this safety control, choose OEM.

Installation Difficulty

Easy (2/5). Disconnect power, unplug the leads, remove the two mounting screws, and install the replacement flush against the bulkhead. Roughly 10–15 minutes. If the limit was tripping, address the airflow cause before returning the furnace to service.
