Goodman 20162903 Primary Limit Switch (150°F)

The Goodman 20162903 is a genuine OEM primary limit switch rated at 150°F for the WFD195090S4CAB gas furnace. Mounted on the heat-exchanger plenum, this high-limit control monitors supply-air temperature and shuts off the burners if the furnace overheats due to a dirty filter, blocked ducts, or blower failure. It protects the heat exchanger from cracking and prevents unsafe operating temperatures.

Specifications

Trip point: 150°F cutout (primary high limit)
Type: Auto-reset temperature limit switch
Function: Disables burners on over-temperature
Terminals: 1/4 in. quick-connect spade
Fit: Direct OEM replacement for Goodman WFD195090S4CAB

OEM vs. Generic

The 150°F calibration is specific to this furnace's plenum design and airflow. A genuine OEM switch trips at exactly the right temperature; generic substitutes with different set points cause short-cycling or fail to protect the heat exchanger. For a primary safety limit, OEM is strongly recommended.

Install Difficulty

Easy (2/5). Cut power, unplug the two spade terminals, remove the mounting screws, and install the new switch in the same orientation. Typically a 15-minute repair.
