Heil Quaker ICP 34335002 Limit Switch
The ICP 34335002 High Limit Switch is a critical safety component designed for International Comfort Products and Heil Quaker furnace units. This OEM 220-240F auto limit switch functions as a normally closed thermostat disc that monitors heat exchanger temperatures to prevent thermal runaway. When internal plenum temperatures exceed the 240?F threshold, the switch opens the circuit to the gas valve, ensuring the system remains within safe operating parameters. As a genuine ICP replacement part, it handles high-cycle thermal demands without the drift common in aftermarket alternatives. It is a direct fit for C9MPD075F12A1, C9MPD075F12A2, and C9MPD075F12A3 models. For technicians troubleshooting intermittent furnace shutdowns or code-locked ignition sequences, replacing a fouled or out-of-calibration 34335002 limit switch restores the factory-specified safety sequence and prevents nuisance tripping in residential HVAC systems.
Key Benefits
- Exact OEM Specification: Ensures the 34335002 part matches the original furnace high limit temperature settings for precise cut-out performance.
- Automatic Reset Logic: The 220-240F auto limit switch restores the circuit automatically once temperatures drop to the differential setpoint, reducing unnecessary service calls.
- Broad Compatibility: Engineered for seamless integration with Heil Quaker, Comfortmaker, and ICP furnace replacement parts catalogs.
- High-Temperature Durability: Constructed to withstand the harsh environment of the heat exchanger assembly for long-term reliability.
Common Questions
What causes a 220-240F limit switch to trip repeatedly?
Frequent tripping is usually caused by restricted airflow, such as a clogged furnace filter, blocked return ducts, or a failing blower motor, rather than a faulty 34335002 switch itself.
Is the ICP 34335002 switch compatible with other furnace brands?
While it is primarily for International Comfort Products, it may fit other brands under the ICP umbrella. Always verify your specific furnace model number against the technical specifications.
How do I test the 34335002 High Limit Switch?
Using a multimeter, technicians should check for continuity across the terminals when the switch is cool. If the switch remains open at room temperature, it has failed and requires immediate OEM replacement.
