Goodman 20162906 M4 Primary Limit Switch

The Goodman 20162906 is a genuine OEM M4 primary high-limit switch for the AMS951155DXA gas furnace and compatible Goodman/Amana models. This thermally activated safety control monitors heat-exchanger temperature and opens the circuit to shut off the burners if the furnace overheats — protecting against cracked heat exchangers, blower failures, and restricted airflow. A tripped or failed limit switch is a leading cause of a furnace that short-cycles or won't stay lit.

Type: M4 primary (high) limit switch

OEM vs. Generic
