The Goodman 20162904 is a genuine OEM primary high-limit temperature control built for the AMH950904CXAF gas furnace and compatible Goodman/Amana models. This safety switch monitors heat-exchanger temperature and opens the circuit to shut down the burners if the furnace overheats — a critical protection against cracked heat exchangers and fire hazards.

Specifications

Type: Primary high-limit / temperature control
Function: Auto-open on over-temperature, auto-reset
Role: Furnace safety limit
Fit: Goodman/Amana AMH950904CXAF and compatible furnaces
OEM part number: 20162904

OEM vs. Generic

The OEM 20162904 is calibrated to the exact trip temperature and mounting geometry Goodman specifies for this furnace. Generic limit switches may trip at the wrong setpoint, leading to short-cycling and no-heat calls, or fail to protect the heat exchanger. On a safety component, matching the OEM specification is the right choice.

Install Difficulty

Easy to moderate. The limit is typically held by two screws with spade-terminal wiring. Turn off power at the furnace before servicing. A handy DIYer can complete the swap, though a technician should confirm proper reset behavior and airflow after installation.
