Heil Quaker ICP 1004304 Rollout Switch

The Heil Quaker ICP 1004304 Rollout Switch is a critical safety component designed to monitor temperatures near the burner assembly of high-efficiency gas furnaces. Rated for a fixed trip point of 350 degrees F, this Single Pole Single Throw (SPST) sensor provides immediate circuit interruption if it detects flame spillage or excessive heat outside the combustion chamber. As a Manual Reset device, it forces a technician to identify and resolve underlying issues—such as a cracked heat exchanger, blocked flue, or failed inducer—before the system can be fired again. This genuine OEM furnace replacement part is engineered for precision, ensuring the limit switch opens reliably to prevent fire hazards or carbon monoxide accumulation. Whether you are servicing a Heil, Tempstar, or Comfortmaker unit, this 1/4-inch quick-disconnect switch is the standard for maintaining UL-compliant safety protocols in residential heating systems.

Key Benefits for Technicians:

• High-Temperature Precision: Factory-calibrated to 350 degrees F for specialized high-heat applications.
• Failsafe Design: The Manual Reset functionality ensures the furnace remains locked out until the cause of the rollout is professionally diagnosed.
• Broad Compatibility: Direct replacement for ICP 1004304 across brands like Heil, Keeprite, Day & Night, and Kenmore.
• Standardized Wiring: Features standard 1/4" terminals for seamless integration into existing SPST safety loops.

Common Questions:

Why does the ICP 1004304 rollout switch keep tripping?
Repeated tripping typically indicates a flame rollout condition caused by inadequate draft, a blocked vent pipe, or a compromised secondary heat exchanger. Never bypass this switch; perform a full combustion analysis to locate the restriction.

Can I replace a 350F switch with a lower temperature rating?
No. You must match the original manufacturer specifications. Using a lower-rated switch will cause nuisance tripping, while a higher-rated switch compromises the safety of the furnace cabinet.

How do I test for a faulty rollout switch?
With the power off and wires disconnected, use a multimeter to check for continuity. If the button is depressed but the circuit remains open, the internal snap-disc is likely damaged and requires a replacement rollout switch.
