Laars Heating Systems 2400-058 Limit Switch
The Laars Heating Systems 2400-058 Limit Switch is a high-precision, 24V thermal safety component engineered for critical boiler applications. Featuring an automatic reset configuration, this thermal cut-out is designed to maintain operational safety by monitoring internal temperatures within a 140°F to 180°F range. As a direct replacement HVAC limit switch, the 2400-058 ensures the system cuts out at the 180°F high-limit set point and automatically re-engages once the temperature drops to the 140°F threshold. This responsive Teledyne Laars part prevents heat exchanger damage by interrupting the burner circuit during restricted airflow or excessive heat buildup, providing the necessary protection for boiler system integrity.
Key Benefits:
- Precision Temperature Control: Calibrated for a 140°F cut-in and 180°F cut-out to prevent system overheating.
- OEM Compatibility: Specifically designed for Laars Heating Systems and Teledyne Laars boilers, ensuring a perfect fit and electrical match.
- Automated Operation: The automatic reset limit switch eliminates the need for manual intervention after a temporary high-temperature event once the system cools.
- Voltage Reliability: Standard 24V electrical specification integrates seamlessly with existing low-voltage control circuits.
Common Questions:
What causes a Laars 2400-058 limit switch to trip frequently?
Frequent tripping usually indicates restricted airflow, often due to a clogged filter or a failing blower motor. If the switch remains open despite normal temperatures, use a multimeter to check for electrical continuity across the terminals.
Is the 2400-058 a manual or automatic reset switch?
This model is an auto-reset limit switch. It will automatically close the circuit and allow the burner to fire again once the sensor detects the temperature has fallen back to the 140°F cut-in level.
Can I use this limit switch on other boiler brands?
While the thermal specifications are 140-180°F, this Laars boiler part is intended for use in specific Teledyne Laars and Laars units. Consult the technical manual of your equipment to verify the exact part number requirements before installation.
