Heil Quaker ICP 611891 Relay
The Heil Quaker ICP 611891 Relay is a high-performance combustion air relay specifically engineered for International Comfort Products (ICP) heating systems. Primarily utilized in gas and oil-fired applications, this 24V furnace relay (Potter & Brumfield KUMP-12AT8-24) acts as a critical switching interface between low-voltage signals and high-power combustion components. As a genuine OEM HVAC replacement part, it ensures precise timing and sequence of operation for the combustion air supply, optimizing airflow and preventing inefficient fuel burn. This plug-in general purpose relay features 3-pole single-throw functionality and is rated for 50/60Hz, supporting inductive loads with a maximum of 15.0 amps. It is the direct replacement for legacy part numbers 1420510, 1420831, 1420844, and 1420848. Field techs should note that modern iterations of the 611891 may feature a more compact footprint than original mechanical solenoid units, potentially requiring minor drilling for mounting bracket alignment in older Heil, Tempstar, or Comfortmaker furnaces.
Key Benefits- Direct OEM Compatibility: Engineered to fit a wide range of ICP brands, including Heil, Tempstar, Arcoaire, and Comfortmaker models like the NUGK050CF02 and PYMA060G1.
- Enhanced Durability: Solid-state construction offers superior longevity over older mechanical solenoid relays, reducing the risk of contact pitting or failure under high-cycle conditions.
- Broad Electrical Rating: Capable of handling up to 1/3 HP at 120V and 1/2 HP at 600V, providing versatile furnace control board integration.
- Simplified Installation: Comes as a comprehensive kit that typically includes necessary spade terminals for immediate field implementation.
What are the symptoms of a failing combustion air relay?
Technicians commonly report furnace "lockout" cycles or the combustion blower failing to initiate despite a 24V call from the thermostat. Testing for 24V AC across the coil pins with a multimeter usually confirms if the relay is receiving a signal but failing to close the high-voltage circuit.
Is this a direct fit for older mechanical relays?
While electrically identical, the 611891 is a compact relay kit. If you are replacing an older style mechanical relay, the terminal spacing and mounting holes may differ slightly, requiring minor cabinet adjustments or lead extensions.
Can I use this relay for 50Hz and 60Hz systems?
Yes, the 611891 is rated for 50/60Hz operation, making it suitable for both standard North American 60Hz grids and international 50Hz power configurations.
