Goodman 20162903 Primary Limit Switch (150°F)

The Goodman 20162903 is a genuine OEM primary high-limit switch rated at 150°F, designed for the AMEC961005CNAB gas furnace. This safety control monitors the temperature in the heat exchanger area and shuts off the burners if the furnace overheats — typically from restricted airflow, a dirty filter, or a failing blower. A properly functioning limit switch is essential to prevent heat-exchanger damage and unsafe operating conditions.

Specifications

OEM Part Number: 20162903
Type: Primary high-limit safety switch
Trip Temperature: 150°F (opens on rise)
Fits: Goodman / Amana AMEC961005CNAB gas furnace
Function: Cuts burner operation on overheat

OEM vs. Generic

The genuine Goodman limit switch is calibrated to the exact 150°F trip point and matches the factory mounting bracket and terminal layout. Generic switches with incorrect trip temperatures or bracket geometry can cause short cycling, premature shutdowns, or fail to protect the heat exchanger. OEM is the safe, drop-in choice.

Installation Difficulty

Easy to moderate. Cut power at the disconnect, remove the two mounting screws, transfer the wire terminals, and reinstall. No brazing or gas work required. Confirm the correct part and trip temperature against the furnace wiring diagram before powering back up.
