Heil Quaker ICP 34335001 Limit Switch

The Heil Quaker ICP 34335001 Limit Switch is a critical safety component designed for precise thermal monitoring in high-efficiency gas furnaces and air handlers. As a veteran-grade furnace high limit switch, this genuine OEM replacement part features a normally closed circuit that triggers an open on temperature rise at 210?F to protect the heat exchanger from structural damage. Once the system plenum cools to the 190?F cut-in temperature, the automatic reset limit switch restores the circuit, allowing for standard ignition sequences to resume. This specific ICP 34335001 disc-style control is engineered for 125-250V applications and is compatible with a wide range of International Comfort Products equipment, including Heil, Tempstar, and Comfortmaker units. For contractors troubleshooting short-cycling or "limit circuit lockout" codes, replacing a worn 34335001 thermostat disc ensures the system operates within its engineered thermal parameters, maintaining both equipment integrity and occupant safety.

Key Benefits for HVAC Professionals

  • Precise Thermal Calibration: Reliable 190-210?F operating range prevents premature trips while ensuring robust overheat protection.
  • OEM Compatibility: Exact drop-in replacement for Heil Quaker 34335001, 313408, and TOD 60T11 models, eliminating the need for field modifications.
  • Automatic Reset Functionality: Minimizes nuisance service calls by restoring system operation once the unit reaches safe temperatures.
  • Rugged Construction: Built to withstand the high-cycle demands of modern furnace heat exchangers.

Common Technical Questions

How do I verify if the 34335001 limit switch is faulty?
Use a multimeter to check for continuity across the terminals while the furnace is cool. This is a normally closed switch; if you find infinite resistance (no continuity) at room temperature, the switch is stuck open and requires replacement. Also, verify that the blower motor is moving sufficient CFM, as restricted airflow?not a bad switch?is the primary cause of limit trips.

What furnace models are compatible with this limit switch?
This part is widely used in ICP-branded equipment, including N9MP, C8DNL, and GDE series furnaces. It serves as a direct replacement for various Heil, Tempstar, Arcoaire, and Snyder General models. Always cross-reference your specific model number before installation.
