  • High-Capacity Blower Support: Features heavy-duty 20 Amp relays for both heat and cool blower functions, ensuring reliable power delivery.
  • Wide Voltage Range: Designed to operate reliably within a line voltage range of 98-132 VAC, accommodating minor fluctuations in power supply.

Pro-Tip: Check the Blower Speed Taps                                                                                      The ICM289 manages various time delays. When installing this board, always confirm the correct speed tap connections on the board's terminals (e.g., HEAT, COOL, FAN) match your furnace's wiring diagram. Incorrect speed settings are a primary source of airflow issues and can cause limit switch trips shortly after startup.
