Heil Quaker ICP 1171476 Limit
The Heil Quaker ICP 1171476 Limit Switch is a critical safety component designed for precise thermal monitoring within high-efficiency gas furnaces and HVAC systems. Engineering specifications for this L130-30 limit control dictate an open temperature of 130?F with a fixed 30?F reset differential, ensuring the burner circuit breaks upon reaching the overhead threshold to prevent heat exchanger damage. This OEM replacement part is essential for maintaining the safety loop in ICP, Heil, and Tempstar equipment, allowing for standard fixed-mount installation within the furnace plenum. As a SPST (Single Pole Single Throw) switch, the 1171476 provides reliable normally closed contact operation, cycling open only when temperatures exceed factory-set limits. Professional contractors prioritize these limit reset switches for their tight tolerances and compatibility with integrated furnace controllers, ensuring consistent system protection across various residential heating units and packaged HVAC systems.
Key Technical Benefits
- Precision Thermal Calibration: Factory-set for an L130 opening point to protect against airflow restrictions.
- Reliable Differential: Features a 30-degree reset to prevent rapid short-cycling and ensure system stability before restart.
- Broad OEM Compatibility: Directly replaces multiple ICP and Heil Quaker part numbers for streamlined truck stock maintenance.
- Durable Construction: Engineered to withstand high-cycle environments within forced-air furnace heat exchangers.
Common Technical Questions
What causes a limit switch to trip frequently?
A tripped limit switch typically indicates restricted airflow, often caused by a clogged furnace filter, undersized ductwork, or a failing blower motor.
Is this switch a manual or automatic reset?
The ICP 1171476 is an automatic reset limit, meaning it will re-close the circuit once the temperature drops below the 100?F reset point.
Can I substitute this with a higher temperature limit?
Never bypass or upgrade the temperature rating of a limit control; higher thresholds can lead to cracked heat exchangers or fire hazards.
Notes
Item is Non Cancelable / Non Returnable
