Goodman 20162903 Primary Limit Switch (150°F)

The Goodman 20162903 is a 150°F primary limit switch for the WGFM195090S5DAB gas furnace. Mounted on the heat exchanger/blower compartment, this bimetal-disc control monitors supply-air temperature and interrupts the burner circuit if the furnace overheats — typically caused by a dirty filter, blocked ducts, or a failing blower. It is auto-resetting, closing again once temperature returns to a safe range. Correct trip temperature is critical for both safety and comfort.

Trip Point: 150°F (open on rise)
Reset: Automatic
Function: Supply-air overheat / heat-exchanger safety cutoff
Fits: Goodman WGFM195090S5DAB and compatible furnaces

OEM vs. Generic

The OEM Goodman limit is factory-set to the exact 150°F trip point specified for this furnace. Generic switches with a different rating can cause short-cycling on heat or fail to protect the heat exchanger. For a safety limit, match the OEM temperature spec.

Installation Difficulty

Easy (2/5). Power down, disconnect the terminals, remove two mounting screws, and install the replacement. Correct any underlying airflow restriction before returning the furnace to service.
