Goodman 20162903 Primary Limit Switch (150°F)

The Goodman 20162903 is a genuine OEM primary limit switch rated at 150°F for the GKS90703BXAG gas furnace and compatible Goodman/Amana models. This temperature-sensing safety control monitors supply-air temperature in the heat exchanger area and opens the circuit to shut off the burners if the furnace overheats — protecting against restricted airflow, a dirty filter, or blower failure. It automatically resets once temperatures return to a safe range.

Specifications

Type: Primary limit / high-temperature switch
Trip Point: 150°F
Reset: Automatic
Contacts: Normally closed (opens on overheat)
OEM Part Number: 20162903
Fits: Goodman GKS90703BXAG and compatible furnaces

OEM vs. Generic

The OEM switch is calibrated to the exact 150°F factory trip point and mounting flange — the reliable choice for a safety control. The generic option is an equivalent aftermarket limit switch at a lower price; verify the temperature rating and flange match your model.

Installation Difficulty

Easy (1/5) — Two spade terminals and typically two mounting screws. Power off the furnace, transfer the wires, and secure the new switch in the original location. If the limit trips repeatedly, check airflow and the filter before assuming a bad switch.
