Goodman 20162903 Primary Limit Switch (150°F)

The Goodman 20162903 is a genuine OEM primary high-limit switch rated to open at approximately 150°F, built for the GMH950703BXAB gas furnace and compatible Goodman/Amana units. This normally-closed thermal safety control monitors heat-exchanger/plenum temperature and shuts off the burners if the furnace overheats — protecting against restricted airflow, dirty filters, or blower failure. A tripped or failed limit switch is a common cause of short-cycling and no-heat calls.

Specifications

Trip temperature: 150°F (auto-reset)
Configuration: Normally closed (opens on rise)
Function: Primary high-limit safety switch
Fits: Goodman GMH950703BXAB and related furnaces
OEM Part #: 20162903

OEM vs. Generic

OEM limit switches carry the exact trip temperature and mounting footprint Goodman engineered for this furnace. Generic switches with different set points can nuisance-trip or fail to protect the heat exchanger. For a safety-critical control, choose OEM.

Installation Difficulty

Easy (1/5) — Two spade terminals and typically two mounting screws. Cut power at the breaker before replacing. A multimeter confirms continuity for diagnosis.
