Goodman 20162903 Primary High-Limit Switch (150°F)

The Goodman 20162903 is a genuine OEM primary limit switch calibrated to open at 150°F, installed on the Amana/Goodman AMH950905DXAA 95% gas furnace. This automatic-reset safety control monitors supply-air temperature and shuts off the burners if the heat exchanger overheats — protecting against a failed blower, blocked filter, or restricted ductwork. A tripped or open limit switch is a common cause of a furnace that lights then shuts down on high temperature.

Specifications

Trip temperature: 150°F (opens on rise)
Reset: Automatic
Function: Primary high-limit safety control
Fits: AMH950905DXAA and compatible Goodman/Amana furnaces
Type: Direct OEM replacement

OEM vs. Generic

The OEM 20162903 ships with the exact 150°F calibration and factory mounting bracket for a true drop-in fit. Generic limits often differ in trip point or bracket geometry, which can cause nuisance trips or a mounting mismatch. For a safety control, OEM is the right choice.

Install Difficulty

Easy (2/5) — Cut power, unplug the two spade terminals, remove two mounting screws, and swap in the new switch. About 15 minutes with a nut driver. No calibration required.
