Amana-Goodman 10728306 Limit Switch

The Amana-Goodman 10728306 Limit Switch is a factory-authorized OEM replacement part engineered for precise thermal regulation across a wide array of Goodman and Amana HVAC systems. Designed for high-limit safety monitoring, this bimetal disc thermal switch features a critical 200°F (L200-40) open temperature and a 160°F reset point, ensuring the furnace high limit prevents heat exchanger overheating. This component is essential for maintaining the sequence of operation in condensing units, heat pumps, and air handlers. Built to exact MRO (Maintenance, Repair, and Operations) standards, the 10728306 offers a drop-in fit for quick field installation, restoring the safety circuit integrity of the equipment. Pro-tier construction ensures reliable HVAC circuit protection and cycling endurance, making it the preferred choice for service technicians diagnosing limit switch tripping issues in residential and light commercial forced-air applications.

• Exact OEM Specifications: Eliminates compatibility risks associated with universal parts in Amana and Goodman furnaces.
• Broad System Compatibility: Rated for use in package units, air handlers, and split system heat pumps.
• Critical Safety Parameters: Precise 200-degree cutout ensures the system stays within safe operational thermal limits.
• Automatic Reset: Resets at 160°F to resume normal operation once internal temperatures have stabilized.
• Optimized Lead Connectivity: Standard terminal configuration for fast integration into existing wire harnesses.

What causes a furnace limit switch to trip repeatedly?
Repeated tripping is usually indicative of restricted airflow caused by a dirty air filter, blocked return vents, or a failing blower motor. Always verify static pressure before replacing the 10728306 limit switch.

Can this switch be used in both gas furnaces and electric air handlers?
Yes, this specific OEM limit switch is rated for multiple configurations including heat pumps and furnace units as long as the 200°F thermal requirement matches the data plate.

Is this a manual or automatic reset switch?
The 10728306 is an automatic reset thermal switch, meaning it will close the circuit once the temperature drops to 160°F.
