Amana-Goodman B1370187 Limit Switch Durable Construction: Fabricated from high-gradeThe Amana Goodman B1370187 Limit Switch is a critical OEM safety component engineered for high static furnace environments. As a primary auto limit switch, it monitors internal plenum temperatures to protect the heat exchanger from hazardous overheating. This specific model is calibrated with a 160 degree F cutout and a 130 degree F cut in reset point, ensuring the system interrupts the heating cycle if airflow becomes restricted due to a clogged
