Amana-Goodman 10728338 Limit Switch

The Amana-Goodman 10728338 Limit Switch is a critical OEM safety component designed for precise thermal regulation within furnace blower assemblies and heat exchangers. This furnace high limit switch features a 3-inch insertion length and is factory-calibrated for an L215-75F temperature rating, meaning it opens the circuit at 215°F and automatically resets once temperatures drop to 75°F. Engineered for durability in high-cycle environments, this HVAC replacement part ensures the system stays within safe operating parameters to prevent heat exchanger damage or fire hazards. The 10728338 serves as a direct OEM limit switch replacement for obsolete part numbers 10728326 and AMA107283-26, making it essential for maintaining equipment certification. When diagnosing furnace limit switch tripping issues in Goodman or Amana units, this component provides the exact electrical specifications and mounting footprint required for a secure, code-compliant installation.

• Precise Thermal Protection: Rated at L215-75F to prevent system overheating.
• Broad Compatibility: Direct replacement for Amana-Goodman 10728326 and AMA107283-26.
• OEM Standards: Guaranteed fitment for specific 3-inch probe applications.
• Automatic Reset: Eliminates service calls for manual resets after standard cooling cycles.

Common Questions:

What causes a furnace limit switch to trip repeatedly?
Repeated tripping is usually caused by restricted airflow, often due to a clogged filter, blocked return air, or a failing blower motor. If airflow is sufficient and the switch opens below 215°F, the Amana limit switch itself may be failing.

Is the 10728338 compatible with older Goodman models?
Yes, this is the designated Goodman furnace part for systems requiring a 3-inch probe and an L215-75F temperature profile, specifically replacing older part number 10728326.

How do I verify if this limit switch is the correct replacement?
Check the stamping on your existing switch. If it indicates a 215-degree cutout and has a 3-inch probe length, the 10728338 is the correct technical match.
