Heil Quaker ICP 1398442 Fan Relay

For contractors and seasoned HVACR technicians, the Heil Quaker ICP 1398442 Fan Relay (also referred to as a DPST Combustion Fan Relay) is a critical 24-volt component for maintaining precise control over the inducer motor or blower sequence. This Double Pole Single Throw (DPST) relay is engineered by International Comfort Products to handle the heavy-duty cycles found in residential and commercial heating units. By utilizing a 24V coil to actuate dual high-voltage circuits, it ensures synchronous power distribution to multiple components without the risk of cross-circuit interference. When diagnosing a no-heat call where the inducer fails to energize or stays stuck open, replacing the OEM 1398442 relay restores the proper timing of the combustion process. Its robust contact points are designed to resist pitting and carbon buildup, ensuring reliable switching under high-amperage loads. This HVAC induction fan relay is a direct-fit replacement for various Heil Quaker, Tempstar, and Comfortmaker models, streamlining the repair process and ensuring system safety.

• OEM Precision: Genuine International Comfort Products part ensures 100% compatibility with specific Heil Quaker furnace models.
• Dual-Circuit Control: The DPST configuration allows for simultaneous switching of two separate electrical paths using a single 24V signal.
• Enhanced Durability: Specifically designed to handle the high-cycle demands of combustion fan motor applications.
• Standardized Terminals: Features standard spade connectors for rapid, wire-for-wire field replacement, reducing downtime.
• Reliable Sequencing: Prevents erratic blower operation and ensures the combustion fan reaches appropriate speeds before ignition.

Is the ICP 1398442 a direct replacement for 24V sequencers?
While often listed alongside sequencers, this is a dedicated DPST Combustion Fan Relay. While it performs switching duties similar to a sequencer, its primary function is direct fan control. Always verify the terminal markings on your existing part before installation.

What are the symptoms of a failing fan relay?
A faulty 1398442 relay typically presents as a "clicking" sound without fan activation, a fan that never shuts off, or a failure to initiate the combustion cycle during the call for heat. You should measure 24V at the coil with a multimeter to confirm the thermostat signal is reaching the relay.

Can I use this relay in non-ICP units?
Technically, this is an HVAC 24V relay designed for the International Comfort Products family. While the DPST specifications may match other universal applications, using this OEM part ensures the load rating and physical footprint are correct for Heil Quaker equipment.
