The Goodman 20162904 Primary Limit Temperature Control is a genuine OEM high-limit safety switch for the Goodman/Amana AMH80803BXBC 80,000 BTU gas furnace. Mounted on the heat-exchanger bulkhead, it monitors supply-air temperature and opens the circuit to shut off the burners if the furnace overheats — the primary defense against a cracked heat exchanger caused by restricted airflow (dirty filter, blocked vents, or blower failure).

Specifications

Type: Primary high-limit temperature control (auto-reset)
Operation: Normally closed, opens on high supply-air temperature
Fits: Goodman/Amana AMH80803BXBC and compatible 80% AFUE furnaces
Mounting: Bulkhead bracket, 1/4 in. spade terminals
Application: Furnace over-temperature safety limit

OEM vs. Generic

Trip temperature and insertion depth are model-specific. Our genuine OEM 20162904 matches Goodman's exact calibration and mounting geometry, preventing nuisance lockouts and ensuring proper protection. Substitutes with a different set point can compromise safety — OEM recommended.

Installation Difficulty

Easy (2/5). Disconnect power, remove two spade connectors and the mounting screws, then install the new limit in the same orientation and depth. If the old limit tripped, always correct the airflow or blower fault first.
