Heil Quaker ICP 1320447 Rollout Switch

The Heil Quaker ICP 1320447 Rollout Switch is a critical safety component designed for specific gas-fired furnace applications, including several Inter City Products (ICP), Comfortmaker, and Tempstar models. This SPST (Single Pole Single Throw) safety device monitors the burner compartment for flame rollout conditions, immediately interrupting the 14V or 24V signal to the gas valve if excessive heat is detected. Engineered with a 300-degree F open temperature and a 40-degree F automatic reset, this switch ensures that your HVAC system remains protected without requiring a manual reset for minor ambient temperature fluctuations once the rollout condition is cleared. Its robust construction is built to withstand the high-heat environment of the burner assembly, providing reliable furnace limit control and ensuring OEM compatibility during emergency repairs or routine maintenance.

• Automatic Reset Functionality: Simplifies troubleshooting by resetting once temperatures drop to 40 degrees F, reducing unnecessary callbacks for minor trips.
• Precise Thermal Calibration: Calibrated to open exactly at 300 degrees F to prevent heat exchanger damage and hazardous exhaust leaks.
• Broad ICP Compatibility: Direct replacement for several Heil Quaker and ICP furnace parts, ensuring a perfect fit and proper alignment on the burner shield.
• Durable SPST Circuitry: High-quality internal contacts maintain low resistance for consistent signal flow to the furnace control board.

What causes this rollout switch to trip frequently?
Frequent trips usually indicate a cracked heat exchanger, a clogged flue pipe, or improper gas pressure causing the flame to roll out of the combustion chamber.

Can I use this switch in a manual reset application?
No, this is an automatic reset switch. It is essential to match the reset type and temperature rating of the original equipment to maintain the UL safety certification of the furnace.

How do I verify if the 1320447 switch is faulty?
Check for continuity across the terminals at room temperature using a multimeter. If the circuit is open while the unit is cool, the thermal limit has failed and the switch must be replaced.
