Heil Quaker ICP 1171475 Limit
The Heil Quaker ICP 1171475 Limit Switch is a critical safety component engineered for precision thermal monitoring in ICP residential furnaces and HVAC systems. This fixed temperature limit control is calibrated to an open temperature of 140?F with a 30?F differential, ensuring the heat exchanger does not exceed safe operating parameters. Designed as a direct replacement part for Heil Quaker, Comfortmaker, and Tempstar units, this switch features a standard L140-30 furnace limit configuration to maintain system integrity during high-heat cycles. As a specialized HVAC high limit sensor, it utilizes a bimetallic disc to interrupt the burner circuit upon reaching its setpoint, effectively preventing equipment damage. When diagnosing furnace limit switch tripping, this OEM-spec component ensures exact electrical ratings and mounting alignment required for ICP furnace repair and long-term reliability in the field.
Key Benefits for Contractors:
- Precise Thermal Calibration: Fixed 140-degree opening point specifically matched to ICP heat exchanger specifications to prevent overheating.
- Automatic Reset Functionality: Features a 30-degree reset differential, allowing the system to resume operation once the plenum temperature drops to 110?F.
- OEM Compatibility: Designed for seamless integration with Heil Quaker 1171475 models, ensuring proper spade terminal fitment and mounting depth.
- Durable Construction: Built to withstand the high-temperature environment of a furnace cabinet without drift in setpoint accuracy.
Common Questions:
What causes a 140-30 limit switch to trip frequently?
Frequent tripping is usually indicative of restricted airflow, often caused by a dirty air filter, blocked return air ducts, or a failing blower motor rather than a faulty 1171475 switch itself.
Can I substitute this with a limit switch of a different temperature rating?
No. In ICP HVAC troubleshooting, using a limit with a higher opening temperature creates a safety hazard, while a lower temperature will cause nuisance tripping. Always match the L140-30 specification.
Is the 1171475 limit switch orientation-sensitive?
The switch should be mounted in the original factory location using existing mounting holes to ensure the sensing element stays in the direct path of the airflow for accurate monitoring.
Item is Non Cancelable / Non Returnable
