The Goodman 20162903 Primary Limit Switch is a genuine OEM high-limit safety control rated to 150°F for the WGFM195070S4CAB gas furnace. Mounted on the heat-exchanger/plenum, it monitors supply-air temperature and opens the burner circuit if the furnace overheats — typically from a dirty filter, blocked ducts, or a failing blower. As an auto-reset device it re-closes once the temperature drops back into range, allowing normal operation to resume after the cause is cleared.

Type: Primary high-limit switch, auto-reset
Trip point: 150°F
Function: Normally closed, opens on overheat
Terminals: 1/4" quick-connect spade
Fit: Goodman WGFM195070S4CAB and compatible models
Part: OEM Goodman 20162903

OEM vs. Generic: The OEM 20162903 carries the exact 150°F calibration and disc geometry Goodman specifies for this plenum, ensuring it protects the heat exchanger without nuisance tripping. Generic limits with a slightly different set-point or mounting can shut the furnace down prematurely or, worse, respond too slowly. For a safety control, match the OEM part.

Install difficulty: Easy (1/5). Cut power, unplug the two spade terminals, remove the two mounting screws, install the new limit in the same position, and reconnect. About 10 minutes. Repeated tripping points to restricted airflow — check the filter and blower before returning to service.
