Trane SWT1652 Limit Switch
The Trane SWT1652 Limit Switch is a critical safety component designed for high-limit temperature monitoring in residential and commercial HVAC units. This OEM Trane replacement part features a fixed temperature range of 200-230°F, ensuring the system shuts down power to the gas valve or heating elements if internal temperatures exceed safe operating parameters. Often utilized as a furnace high limit switch, the SWT1652 utilizes a 3-inch insertion depth to accurately sample airflow temperatures within the heat exchanger or plenum. The automatic reset functionality allows the switch to close the circuit once temperatures return to a safe level, preventing unnecessary system lockouts while maintaining rigid safety standards. This bimetal disc limit switch is engineered for high-cycle reliability and is a direct replacement for many American Standard and Trane air handlers and furnaces requiring a L230-30 limit switch configuration.
Key Benefits for Contractors- Precise Thermal Protection: Fixed 200°F to 230°F range provides reliable furnace temperature regulation.
- OEM Compatibility: Exact Trane SWT01652 replacement ensures proper fitment and electrical termination without field modifications.
- Standardized Insertion: The 3-inch probe depth is optimized for bypass air monitoring and heat exchanger protection.
- Auto-Reset Logic: Minimizes nuisance service calls by automatically restoring system operation after a cooling period.
What causes a Trane SWT1652 to trip frequently?
Frequent tripping usually indicates restricted airflow, often due to a clogged air filter, undersized ductwork, or a failing blower motor. If the switch remains open when cool, the bimetal disc may have failed.
Can I use a higher temperature limit switch if this one keeps tripping?
No. The limit setting is engineered specifically for the heat exchanger's metallurgic limits. Replacing a 230°F switch with a higher rating can lead to equipment damage or fire hazards.
Does this switch require manual resetting?
The SWT1652 is an automatic reset switch. It will reset itself once the temperature drops approximately 30-40 degrees below the trip point.
