The genuine Goodman/Amana 20162904 Primary Limit Temperature Control is the OEM high-limit safety switch for the AMES800603BNAA gas furnace and compatible Goodman/Amana models. Mounted on the heat exchanger, this primary limit continuously monitors plenum temperature and shuts down the burners if the furnace overheats — protecting the heat exchanger and preventing a fire hazard.

Specifications

Part type: Primary high-limit temperature control switch
Function: Automatic burner shutdown on over-temperature
Reset: Automatic (temperature-based)
Fits: AMES800603BNAA and related Goodman/Amana gas furnaces
Brand: Genuine OEM Goodman/Amana

OEM vs. Generic

The OEM 20162904 is calibrated to the precise open/close temperature set points engineered for this furnace and mounts in the factory location. Generic limits with incorrect trip temperatures can cause nuisance shutdowns, short cycling, or fail to protect the heat exchanger. As a primary safety device, the exact OEM control is the recommended choice.

Installation Difficulty

Easy to Moderate — Typically two mounting screws and two spade terminals. Power off the furnace at the disconnect first. A basic DIYer comfortable with wiring can replace it; if the furnace repeatedly trips on limit, have a technician diagnose the underlying airflow issue.

Keep your furnace running safely with a genuine Goodman/Amana primary limit control.
