Utica-Dunkirk 29388 Contorl Board

The Utica-Dunkirk 29388 Fan Timer Control Board is a critical OEM replacement part engineered for precise timing and sequencing in high-efficiency hydronic heating systems. As a direct substitute for the legacy United Technologies 1158-120, this board manages the induction of the fan blower motor, ensuring optimal post-purge cycles and heat distribution. For field technicians, this integrated furnace control (IFC) provides a drop-in solution to resolve common boiler lockout issues, intermittent heating, or failure of the fan to activate after the burners ignite. This Utica-Dunkirk circuit board is designed to match original factory specifications for voltage compatibility and terminal orientation, facilitating a straightforward swap during HVAC preventative maintenance. Its robust construction resists thermal stress, maintaining safe equipment operation and system efficiency throughout the peak heating season. Rely on this genuine replacement part to restore the intelligent logic required for fan timer control in compatible Utica and Dunkirk boiler models.

Key Benefits:

• Direct OEM Swap: Replaces the United Technologies 1158-120, ensuring full compatibility with existing wiring harnesses without field modifications.
• Precise Fan Sequencing: Regulates the timing of the blower motor to optimize heat transfer and prevent the common "cold draft" at the start of a cycle.
• Enhanced Troubleshooting: Provides reliable logic processing to help identify fault codes and system errors during boiler diagnostics.
• High-Durability Logic: Engineered to withstand the electrical demands and thermal fluctuations typical of residential heating system controls.

Common Questions:

• Is this board a direct replacement for the United Technologies 1158-120? Yes, the Utica-Dunkirk 29388 is the official replacement for the discontinued 1158-120 model.
• Will this fix a blower fan that runs constantly? A stuck fan relay on the old board is a primary cause of non-stop blower operation; replacing it with a new 29388 control board typically resolves this failure.
• Does this board work with oil furnaces? While primarily used in Utica-Dunkirk boilers, it is used in several specific multi-brand units (like Olsen) where the 1158-120 was the original spec.
