ICP Limit Switches

The ICP limit switch is a crucial safety component in HVAC systems. The intent of this switch is to keep an eye on the furnace's or the air handling system's temperature. When the temperature reaches a preset limit, the limit switch activates to interrupt the electrical circuit, shutting down the heating system.This function helps prevent the system from overheating, which could otherwise cause equipment damage or pose fire hazards. ICP limit switches are typically adjustable to suit different system requirements and are engineered to withstand the demanding conditions within heating units. They are crucial for maintaining the equipment's safety and ensuring it. Regular maintenance and inspection of these switches are essential for reliable and safe HVAC performance.

FAQs

Can you run an ICP furnace without a limit switch?

No, it is not safe or recommended to operate an ICP furnace without a functioning limit switch. The limit switch is essential for preventing overheating and ensuring safe operation.

How do I test an ICP limit switch?

To test an ICP limit switch, turn off power to the furnace, locate the switch, use a multimeter to check for continuity, and ensure it activates at the correct temperature.
