The Goodman 20269903 Auxiliary Limit Auto-Reset Switch is a genuine OEM overtemperature safety control for Goodman and Amana AMV80905CXA furnaces. This auxiliary limit monitors temperature at a secondary location (commonly near the blower compartment or heat exchanger) and opens the control circuit if it senses excessive heat, protecting the furnace from overheating due to restricted airflow or blower failure. Being auto-reset, it re-closes once temperature returns to a safe range.

OEM vs. Generic

The OEM 20269903 is calibrated to Goodman's exact trip and reset temperatures for this furnace's airflow design. Generic snap-discs may trip at the wrong setpoint, causing either nuisance shutdowns or failure to protect the equipment. Because this is a safety cutout, the OEM part is strongly recommended.

Installation Difficulty: Easy

Power off the furnace, note wire positions, unscrew the mounting bracket, transfer the two spade terminals, and remount. Roughly 15 minutes. No calibration required.
