Goodman 20162903 Primary Limit Switch (150°F)

The Goodman 20162903 is a genuine OEM primary high-limit switch engineered for the AMES960805CNAA gas furnace and other compatible Goodman/Amana heating equipment. This normally-closed thermal safety control continuously monitors supply-air temperature and opens the circuit to the gas valve if the furnace overheats — protecting the heat exchanger, blower, and surrounding components from damage caused by restricted airflow, a dirty filter, or blower failure.

Specifications

Trip temperature: 150°F (open on rise)
Function: Primary high-limit safety switch
Contact type: Normally closed (auto-reset)
Fits: Goodman / Amana AMES960805CNAA and compatible furnaces
OEM part number: 20162903

OEM vs. Generic

The OEM 20162903 is calibrated to the exact trip point specified by the manufacturer for this furnace, ensuring correct safety cut-out and warranty compliance. Generic aftermarket limit switches may carry a similar temperature rating but can differ in mounting geometry, response curve, and long-term reliability. For a safety-critical control, we recommend the OEM part.

Install Difficulty

Easy (1/5). Two-screw mounting with quick-connect spade terminals; typically a 10–15 minute repair. Always shut off power and gas before servicing. If the furnace is repeatedly tripping the limit, diagnose the underlying airflow problem before replacing the switch.
