Heil Quaker ICP 1085928 Control Board

The Heil Quaker ICP 1085928 Control Board is a critical OEM replacement part designed for high-performance fan timing and system sequencing in ICP, Heil, and Tempstar air handlers. This electronic fan timer control manages the critical communication between the 24V thermostat signals and the blower motor relay, ensuring precise airflow delays for both heating and cooling cycles. It features a dedicated 5-amp fuse to protect the low-voltage control circuit from external shorts and a 12-pin Molex connector for a secure, drop-in installation. Engineered to handle both PSC and ECM configurations via jumper selection, this board regulates the sequencer operation and thermal limit monitoring to prevent system overheating. For field technicians, the ICP 1085928 includes integrated diagnostics and clear terminal designations (R, G, W, Y, C) to streamline troubleshooting and ensure the HVAC blower motor operates within factory-specified efficiency parameters.

• Universal Compatibility: Serves as a direct OEM replacement for various ICP, Heil, Tempstar, and Arcoaire air handlers.
• Advanced Fan Timing: Features programmable or fixed delays that optimize blower motor performance and heat exchanger cooling.
• System Protection: Includes an onboard 5-amp blade fuse to safeguard the transformer and integrated furnace control logic from electrical spikes.
• Flexible Applications: Supports both electric heat and heat pump transitions with reliable sequencer logic.

• Does this board support variable speed motors? Yes, ensure you check the jumper settings for ECM vs. PSC motor compatibility as specified in the service manual.
• Why is my blower motor stuck on? A failed fan control board relay is the most common cause of a blower failing to shut off after the thermostat call terminates.
• What leads to the 5-amp fuse blowing? Typically, a short in the 24V thermostat wiring or contact coil will pop the fuse to prevent damage to the 1085928 circuitry.
