Goodman 20162903 Primary Limit Switch (150°F)

The Goodman 20162903 is a genuine OEM primary high-limit switch rated at 150°F for the AMES960403BUAB gas furnace and compatible Goodman/Amana models. This safety control is a normally-closed, temperature-sensing switch mounted on the heat exchanger or blower deck. If supply-air temperature exceeds its 150°F setpoint — typically from a dirty filter, blocked ductwork, or a failing blower — it opens, shutting off the burners to prevent overheating. A tripped or failed limit switch is a common cause of short-cycling and no-heat calls.

Type: Primary high-limit safety switch (normally closed / auto-reset)
Trip point: 150°F
Function: Cuts burner operation on over-temperature to protect the heat exchanger
Fit: Direct OEM replacement for AMES960403BUAB
Brand: Goodman / Amana genuine part
Part number: 20162903

OEM vs. Generic

Because this is a safety-critical control, the trip temperature and mounting bracket must match exactly. A generic switch with the wrong setpoint can allow overheating or cause nuisance trips. The genuine 20162903 is calibrated to the factory 150°F setpoint with the correct bracket footprint, ensuring proper protection and reliable operation.

Installation Difficulty

Moderate. Requires disconnecting power, removing two mounting screws, and transferring the wire connectors to the new switch. Verify correct orientation and secure spade connections. Because this is a safety device, a licensed HVAC technician is recommended if you are unsure of diagnosis or wiring.
