The Goodman 20162904 Primary Limit Temperature Control is a genuine OEM high-limit safety for the AMH950904CXAG furnace and other compatible Goodman and Amana platforms. Mounted on the heat exchanger bulkhead, this primary limit monitors supply-air temperature and cuts the burner if the furnace overheats — protecting the heat exchanger from cracking due to restricted airflow, a dirty filter, or blower failure.

Specifications

Type: Primary high-limit temperature control
Reset: Automatic (recloses when temperature returns to normal)
Function: Opens burner circuit on overheat / airflow loss
OEM Part Number: 20162904
Fits: Goodman / Amana AMH950904CXAG and compatible furnace models
Brand: Genuine OEM Goodman

OEM vs. Generic

This genuine OEM Goodman limit is calibrated to the exact trip temperature and sensing-element length specified for your furnace. Universal aftermarket limits with the wrong setpoint or probe depth can cause short-cycling or, worse, fail to protect the heat exchanger. The OEM control ensures correct, reliable safety response.

Installation Difficulty

Easy to Moderate — usually two mounting screws and two spade connectors, but the sensing element must be seated correctly in the airstream. Disconnect power first. Diagnose and clear any airflow restriction before returning the furnace to service.
