Why Choose This Item

The ICP HQ1084734TD Limit Switch/Thermostat is a practical replacement for compatible International Comfort Products HVAC equipment requiring an L160-30F temperature safety control.

This component helps protect heating systems against excessive temperatures by interrupting the applicable electrical circuit when the designated temperature limit is reached, supporting proper equipment protection and reliable operation.

Replacing a defective high-limit switch may help restore normal heating operation when the existing component causes incorrect temperature-related shutdowns, interrupted heating cycles, or malfunctioning safety controls.

The 160°F nominal limit temperature and 30°F differential designation are important characteristics for selecting the correct replacement thermostat.

The 1084734, HQ1084734TD, and ICP1084734 references provide important identifiers for matching the replacement component to the original equipment.

Please verify the part numbers, L160-30F temperature designation, reset characteristics, electrical voltage and current ratings, terminal configuration, mounting dimensions, and exact ICP equipment model compatibility before purchase.

Safety Note: High-limit thermostats are safety-critical components. Disconnect electrical power and allow heating equipment to cool before servicing. Repeated high-limit activation may indicate restricted airflow or overheating. Never bypass or disable a temperature safety switch. Installation and functional testing should be performed by a qualified HVAC technician according to the manufacturer's specifications.
