Amana-Goodman M0352005 Limit Switch

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.

• 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.

• 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.
