The Goodman 20162903 Primary Limit Switch is a genuine OEM 150°F high-limit safety control for the AMVC80704BXAB variable-speed 80% AFUE furnace. Installed on the heat exchanger or plenum, this automatic-reset switch monitors supply-air temperature and shuts off the burners if the furnace overheats — typically caused by restricted airflow, a dirty filter, or a failing blower. It protects the heat exchanger from cracking and prevents unsafe operating temperatures.

Type: Primary high-limit switch, automatic reset
Trip point: 150°F open on rise
Function: Shuts off burners on plenum overheat
Fits: Goodman / Amana AMVC80704BXAB furnaces
OEM Part #: 20162903

OEM vs. Generic: The exact trip temperature and bracket dimensions matter for a limit switch. The Goodman OEM 20162903 is calibrated to 150°F and drops directly into the factory location. Generic replacements with even a slightly different set point can cause short-cycling or fail to protect the heat exchanger. For proper furnace protection, choose the OEM part.

Install difficulty: Easy (1/5). Two spade terminals and two mounting screws. Cut power to the furnace first, and always confirm airflow issues (filter, blower, ductwork) are resolved — a tripping limit switch is usually a symptom, not the root cause.
