Goodman 20162903 Primary Limit Switch (150°F)

The genuine OEM Goodman 20162903 primary limit switch is a safety control for the Goodman GKS90704CXAA gas furnace. This normally-closed, temperature-sensing switch opens the control circuit when supply-air temperature exceeds its 150°F cutout, shutting off the burners to prevent heat-exchanger overheating from restricted airflow, a failed blower, or a dirty filter.

Specifications

  • OEM Part Number: 20162903
  • Cutout Temperature: 150°F (auto-reset)
  • Function: Primary high-limit safety switch
  • Configuration: Normally closed, opens on temperature rise
  • Fits: Goodman/Amana GKS90704CXAA and compatible furnaces

OEM vs. Generic

Limit switches are life-safety devices. The genuine Goodman switch is calibrated to trip at the exact 150°F rating and mounts with the correct flange and probe depth. Generic switches with different trip points or mounting can cause nuisance shutdowns or, worse, fail to protect the heat exchanger. Always use the OEM-specified rating.

Installation Difficulty

Easy–Moderate (2/5) — Remove two mounting screws, transfer the wire terminals, and reinstall on the correct panel. Do not bypass or jumper a tripped limit switch — diagnose the airflow cause. Turn off power and gas before servicing.

Match part number and cutout rating exactly before ordering.
