Heil Quaker ICP 1173822 Limit Switch
As a seasoned tech, you know that a nuisance trip is often a symptom, but when the Heil Quaker ICP 1173822 Limit Switch fails, your entire heating cycle is dead in the water. This genuine OEM replacement limit switch is a critical safety component designed for International Comfort Products (ICP) equipment, including brands like Heil, Tempstar, and Comfortmaker. It features a fixed setpoint that opens the circuit at 120°F (high limit open 120) to prevent heat exchanger damage and automatically resets, closing at 100°F once the plenum temperature stabilizes. This normally closed furnace switch ensures that if airflow is restricted due to a bogged-down blower or a clogged filter, the burners cut out before things get dangerous. Whether you are working on a gas furnace high limit repair or a routine HVAC safety switch replacement, using this ICP 1173822 snap disc ensures the unit maintains its original specifications and agency listings. The L120-20 temperature limit logic is precise, providing the exact thermal protection required for specific PDS4 and PDD4 series units.
Key Benefits for the Contractor:- Precise Thermal Calibration: Factory-set to open at 120°F and close at 100°F for accurate overheat protection.
- Automatic Reset Function: Eliminates the need for manual intervention once the system reaches a safe reset temperature.
- Original Equipment Reliability: Ensures proper fit and depth in the 1173822 mounting bracket for direct Heil Quaker parts replacement.
- Enhanced System Safety: Protects the heat exchanger from cracking by monitoring air handler internal temperatures.
- Why does my furnace short cycle after installing a new limit switch? Ensure your air filter is clean and the blower motor is moving at the correct RPM; restricted airflow is the #1 cause of limit switch tripping.
- Can I use a universal L120 switch instead? While universal discs exist, using the genuine ICP 1173822 ensures the mounting flange and terminal orientation match the existing wiring harness perfectly.
- What does a 'Limit Switch Open' error code mean? It indicates the circuit has broken because the plenum reached 120°F, or the 1173822 switch has failed and stayed open.
