Goodman 20162903 Primary Limit Switch (150°F)

The Goodman 20162903 is a genuine OEM primary high-limit switch rated at 150°F, designed for the AMH950703BXAB gas furnace. This automatic safety control monitors heat-exchanger temperature and shuts off the burners if the furnace overheats — a critical protection against cracked heat exchangers, restricted airflow, and fire hazards. When a limit switch fails open, the furnace will not fire or will short-cycle on the blower.

OEM vs. Generic

Limit switches are life-safety devices calibrated to a specific trip point and mounting profile. Our OEM 20162903 opens at the exact factory-specified temperature. Generic switches may trip late or nuisance-trip early, defeating the furnace's overheat protection. Always use genuine OEM for safety controls.

Installation Difficulty

Moderate (2/5) — Two-wire connection with two mounting screws; access varies by furnace layout. Cut power at the breaker before servicing. Licensed HVAC technician recommended given the safety role.
