Heil Quaker ICP 34332905 Limit
When you're troubleshooting a furnace that is short-cycling or cutting out under load, the Heil Quaker ICP 34332905 Limit Switch is a critical diagnostic point. This genuine OEM HVAC replacement part features a 3-inch insertion depth, making it a drop-in solution for a wide range of Heil, Quaker, Comfortmaker, and Tempstar air handlers and furnace supply plenums. Designed specifically as a high limit safety device, it monitors internal temperatures within the heat exchanger and breaks the circuit to the gas valve if safe operational thresholds are exceeded. This prevents equipment damage and ensures the system operates within its thermal design parameters.
For service technicians, this ICP furnace limit switch offers the reliability needed to restore proper sequence of operation without the compatibility risks associated with universal after-market components. The 34332905 mechanical limit is built for high-duty cycles and provides precise temperature sensing to maintain safe airflow management. Whether you're dealing with a faulty blower motor causing overheating or restricted airflow from a clogged evaporator coil, this OEM component ensures the unit?s safety circuit remains intact and responsive.
Key Benefits- Direct OEM Compatibility: Verified for use in Heil, Quaker, and other International Comfort Products (ICP) brands like Comfortmaker and Tempstar.
- Precise 3-Inch Insertion: The 3" insertion length provides accurate thermal reading from the center of the air stream.
- Safety Circuit Preservation: Essential for preventing heat exchanger overheating and potential furnace damage.
- Rugged Construction: Engineered to withstand the constant thermal expansion and contraction cycles of residential heating systems.
How do I know if the 34332905 limit switch is failing?
Common indicators include the furnace shutting down prematurely during a heating cycle, the blower fan running continuously even after the heat has stopped, or the system displaying a specific limit circuit error code on the control board.
Can I test this switch with a multimeter?
Yes. With the power disconnected, check for continuity across the terminals. If the switch is open while the furnace is cool, it is likely defective and requires immediate replacement.
What causes this limit switch to trip repeatedly?
Repeated tripping is usually caused by restricted airflow. Check for dirty air filters, blocked return air vents, a malfunctioning blower motor, or debris on the heat exchanger or evaporator coil.
