Description
Overview
The International Comfort Products 1171483 is a 200°F manual reset (M/R) limit switch designed to protect HVAC heating equipment from overheating conditions. When the sensed temperature reaches the 200°F set point, the switch opens the circuit and requires a manual reset before the system can resume normal operation — providing an added layer of safety by preventing automatic restart until a technician has inspected and resolved the underlying cause.
Key Features
- 200°F trip temperature for precise high-limit protection
- Manual reset design requires technician intervention before restart
- Direct OEM replacement for compatible International Comfort Products systems
- Helps prevent equipment damage caused by sustained overheating
- Reliable bimetal sensing element for consistent, repeatable performance
- Compact form factor for straightforward installation in tight equipment spaces
Application
This limit switch is a genuine OEM replacement part intended for use in International Comfort Products (ICP) furnaces and air handlers. It is installed in the heat exchanger or plenum area to monitor supply-air or heat exchanger temperatures. If temperatures exceed the 200°F threshold — due to restricted airflow, a dirty filter, or a blower failure — the switch opens, shutting down the burner and alerting the technician that a manual reset is required.
Why Choose a Manual Reset Limit Switch?
Unlike automatic-reset limit switches, a manual reset device stays open after a fault event. This prevents the equipment from cycling on and off repeatedly during an overheat condition, reducing the risk of heat exchanger cracking, component damage, or fire. It ensures that a qualified technician evaluates the system before it is returned to service.
