The Goodman 20162903 Primary Limit Switch is a genuine OEM high-limit safety control with a 150°F cutout temperature, designed for the Amana/Goodman AMES960403BUAA gas furnace. This normally-closed switch monitors heat-exchanger and plenum temperature and opens to shut off the gas valve if the furnace overheats — a critical safety device that prevents heat-exchanger damage and fire hazards. A failed limit switch is a common cause of furnaces that shut down mid-cycle, short-cycle, or won't fire at all.

Part Number: 20162903
Type: Primary / high-limit switch (auto-reset, normally closed)
Cutout Temperature: 150°F
Fits: Goodman & Amana AMES960403BUAA furnaces
Function: Overheat safety shutoff
Brand: Goodman (Daikin family — Amana compatible)

OEM vs. Generic: The 20162903 is calibrated to the exact 150°F trip point and mounting pattern this furnace requires. Generic limit switches with different set points or bracket geometry can cause nuisance trips or fail to protect the heat exchanger. Because this is a safety component, we strongly recommend the OEM part.

Install Difficulty: Moderate. Requires disconnecting power, removing the burner/control panel, transferring the wire leads, and mounting the new switch in the same location. Basic electrical and HVAC knowledge recommended — roughly 20–30 minutes.

Always disconnect power and shut off gas before servicing. Safety controls should be replaced by a qualified technician when in doubt.
