The International Comfort Products 1320447 is a precision-engineered rollout switch designed to protect furnaces and heating systems from dangerous flame rollout conditions. This SPST (Single-Pole, Single-Throw) safety device monitors burner operation and interrupts the circuit when unsafe temperatures are detected, helping prevent heat exchanger damage, fire hazards, and carbon monoxide risks.
Key Specifications
- Open Temperature: 300°F — trips the circuit when burner rollout is detected
- Close Temperature: 40°F — resets automatically once the unit cools to a safe level
- Reset Type: Automatic Reset — restores operation without manual intervention after cool-down
- Switch Configuration: SPST (Single-Pole, Single-Throw)
- Brand: International Comfort Products (ICP)
- Part Number / SKU: 1320447
How It Works
The rollout switch is mounted near the burner assembly. Under normal operation, combustion gases are drawn into the heat exchanger and vented safely. If a blockage, cracked heat exchanger, or improper airflow causes flames to “roll out” beyond the burner compartment, temperatures at the switch location rise rapidly. When the temperature reaches 300°F, the switch opens the circuit, shutting down the burner to prevent further damage. Once the unit cools to 40°F, the automatic reset function restores continuity, allowing the system to attempt normal operation again.
Benefits
- Protects against flame rollout — a leading cause of furnace fires and CO exposure
- Automatic reset design reduces service call frequency for nuisance trips
- Direct OEM replacement for compatible International Comfort Products furnaces
- SPST configuration ensures straightforward wiring and reliable circuit interruption
- Helps maintain system safety and extend equipment service life
Application
This rollout switch is an OEM replacement part intended for use with compatible International Comfort Products (ICP) furnaces and heating systems. Always verify compatibility with your specific unit model before installation. Installation should be performed by a qualified HVAC technician in accordance with local codes and the equipment manufacturer’s guidelines.
