Heil Quaker ICP 1320364 Limit Switch

The Heil Quaker ICP 1320364 Limit Switch is a critical OEM furnace safety control engineered specifically for International Comfort Products (ICP) equipment. As an auto-reset temperature switch, this component monitors high-side plenum temperatures to prevent thermal runaway and heat exchanger damage. It is calibrated to open the electrical circuit when temperatures reach the 110°F to 130°F threshold, providing essential protection for residential and light commercial forced-air systems. When troubleshooting an ICP furnace limit switch, utilizing this genuine factory part ensures the correct bimetal response time and mounting orientation required for secondary or primary limit applications.

For technicians servicing Heil Quaker heating systems, the 1320364 offers a direct-fit solution that maintains the internal safety string integrity without the calibration drift often found in generic aftermarket controls. This high-limit safety switch is essential for restoring operation after a rollout or overheating event has been corrected, ensuring the blower and burner cycles remain within factory-specified parameters. Whether you are replacing a 1320364 limit control due to fatigue or as part of a seasonal maintenance overhaul, this OEM part provides the exact electrical specifications and thermal tolerances your equipment demands.

Key Benefits for Contractors:

• Automatic Reset Functionality: Restores circuit continuity once the system cools to safe operating temperatures, reducing nuisance service calls.
• Precise Thermal Calibration: Factory-set for 110°F - 130°F to meet specific airflow and heat rise requirements of Heil Quaker and ICP units.
• Direct OEM Compatibility: Eliminates the need for bracket modifications or wiring adapters in compatible ICP gas furnaces.
• Enhanced System Safety: Prevents terminal heat damage by interrupting the gas valve circuit during restricted airflow conditions.

Common Technical Questions:

What causes a Heil Quaker limit switch to trip repeatedly?
Frequent tripping usually indicates restricted airflow, such as a clogged filter, closed registers, or a failing blower motor, causing the plenum temperature to exceed the 130°F threshold.

Is the ICP 1320364 a manual or automatic reset switch?
This is an automatic reset limit switch. It will close the circuit once the bimetal strip cools down, unlike manual reset rollout switches that require a physical button press.

Can I use a higher temperature limit switch instead of the 1320364?
No. Limits are safety-rated for the specific heat exchanger design. Installing a switch with a higher rating than 130°F can lead to equipment failure or hazardous operating conditions.
