The Amana-Goodman M0352005 Limit Switch is a critical safety component designed for precise thermal monitoring in residential gas furnaces. This 160F manual reset limit switch serves as a high-limit safety device, engineered to interrupt the burner circuit if internal plenum temperatures exceed the 160-degree Fahrenheit threshold. As a genuine OEM furnace replacement part, this 1-pole switch (L160F) ensures direct compatibility with Amana, Goodman, and Janitrol systems, effectively replacing legacy part numbers such as 330650 and M03520-05. For service contractors, this HVAC high-limit switch is essential for resolving lockout conditions caused by overheating, often linked to restricted airflow or blower failure. Its manual reset design requires a technician to physically inspect the system before restoring operation, providing an additional layer of diagnostic protection. Utilizing high-quality composite materials and a robust mounting flange, the M0352005 is built for long-term reliability in high-temperature environments. Key Benefits: Exact OEM Specifications: Ensures proper fit and calibrated trip points for Amana and Goodman heat exchangers. Manual Reset Safety: Prevents automatic cycling of a compromised system, requiring a manual override after a high-heat event. Broad Compatibility: Replaces common part numbers including M03520-05 and 330650 across multiple furnace generations. Critical Thermal Protection: Proactively shuts down the gas valve to prevent heat exchanger damage and hazardous operating conditions. Common Questions: Does this switch reset automatically? No, this is a manual reset model (M/R). If the switch trips at 160F, the red button must be depressed once the furnace cools down and the underlying airflow issue is corrected. Which brands is this part compatible with? It is designed for use in Goodman, Amana, and Janitrol gas furnaces. Always verify your specific model number before installation. What causes this limit switch to trip? Common causes include a clogged furnace filter, a failing blower motor, or obstructed ductwork causing the air temperature to exceed the 160F safety rating.
