Amana-Goodman 20162906 Limit Switch

The Amana-Goodman 20162906 Limit Switch is a critical safety component designed for high-static furnace applications, specifically engineered to monitor internal plenum temperatures. This 170F CO AUTO Limit Switch functions as a normally closed thermal sensitive control that opens the electrical circuit when temperatures reach the 170-degree Fahrenheit threshold, preventing heat exchanger damage and ensuring system safety. As a genuine OEM replacement limit switch, the 20162906 offers precise calibration and a reliable automatic reset feature, eliminating the need for manual intervention once temperatures return to safe operating parameters. For HVAC contractors, this high-limit safety control ensures compatibility with specific Amana, Goodman, and Janitrol furnace models, maintaining the integrity of the original equipment's safety circuit. Utilizing genuine HVAC replacement parts like the 20162906 facilitates faster service calls by ensuring exact fitment and terminal alignment for seamless field installation.

• Precise Thermal Protection: Engineered to open at exactly 170°F to protect the heat exchanger from overheating conditions.
• Automatic Reset Functionality: Resets the circuit automatically once the temperature drops, reducing nuisance service calls.
• OEM Compatibility: Designed specifically for Goodman and Amana furnace repair, ensuring electrical specifications match the control board requirements.
• Durable Construction: Built to withstand the high-cycle demands of residential gas furnaces and environmental fluctuations.

What causes a 170F limit switch to trip frequently?
Repeated tripping is usually indicative of restricted airflow, often caused by a restricted air filter, blocked return air ducts, or a failing blower motor.

Is the 20162906 compatible with other furnace brands?
This part is specifically calibrated for Amana, Goodman, and Janitrol equipment. Always verify the furnace limit switch location and part number against the manufacturer’s parts manual.

How do I test the 20162906 limit switch?
Technicians should check for continuity across the terminals at room temperature; the switch should be normally closed. If the circuit is open while the furnace is cool, the switch has failed and requires replacement.
