The Goodman 20162903 Primary Limit Switch (150°F) is a genuine OEM high-limit safety control for the Goodman GKS90704CXAD gas furnace and compatible Goodman/Amana models. Mounted on the heat exchanger or blower deck, this auto-reset switch monitors supply-air temperature and opens the circuit if the furnace overheats — typically due to restricted airflow from a dirty filter, closed vents, or a failing blower. When temperatures return to normal, the switch automatically resets, protecting the heat exchanger from thermal damage.

Specifications

Type: Primary high-limit switch (auto reset)
Trip point: 150°F (opens on temperature rise)
Function: Overheat / airflow-loss safety shutoff
Fit: Goodman GKS90704CXAD and compatible Goodman & Amana furnaces
OEM Part Number: 20162903

OEM vs. Generic

The genuine Goodman OEM limit switch is factory-set to the exact 150°F trip point specified for your furnace. Generic replacements with different set points can nuisance-trip during normal operation or, worse, fail to trip when the unit truly overheats. Because this is a primary safety device, we strongly recommend the OEM part with the correct rating.

Installation Difficulty

Easy (2/5). Disconnect power, note the two wire connections, remove the mounting screws, and install the new switch in the same orientation. About 15 minutes with a screwdriver. If the limit was tripping, replace the air filter and confirm proper blower airflow before returning the furnace to service.
