Modine 5H0806890000 Ignition Control

When you are troubleshooting a Modine unit heater that fails to fire, the Modine 5H0806890000 Ignition Control is often the primary suspect. This OEM intermittent pilot ignition module is the official direct replacement for the legacy 5H80689 and is engineered for 24V 50/60Hz single-phase systems. Operating with a 150mA control draw, this board features a 1-second pre-purge, 90-second trial for ignition, and a 5-minute delay between trials to ensure safe operation. It is compatible with a wide range of natural gas-fired unit heaters, including the Modine BA, BDP, PAE, and BD series. As a veterans in the field know, these UT Electronic Controls Series 003-600A modules are critical for managing the gas valve and spark igniter sequence. Swapping out a faulty Modine 5H0806890000 restores the infinite ignition trial capability required for consistent performance in demanding industrial environments. Always verify your specific unit heater model compatibility and check for 24VAC at the secondary terminals before condemning the existing board.

Key Benefits:

• Direct OEM Replacement: Seamlessly replaces legacy part 5H80689 and various UT Electronic Controls 003-600A series boards.
• Enhanced Logic: Features infinite ignition trials with built-in safety delays to prevent hard lockouts during minor gas pressure fluctuations.
• Broad Compatibility: Validated for use in Modine Hot Dawg (HD), PDP, and PAE series gas-fired unit heaters.
• Robust Construction: Industrial-grade HVAC ignition control board designed to withstand the high-cycle demands of commercial heating.

Common Questions:

How do I know if my Modine ignition control is bad?
Standard diagnostic steps include checking for a 24V signal between the 'Sec' and 'Com' terminals. If you have a call for heat but no spark or gas valve voltage, and your limit switches are closed, the 5H0806890000 likely needs replacement.

What is the difference between the 5H0806890000 and the old 5H80689?
The 5H0806890000 is the updated manufacturer part number. It maintains the same form, fit, and technical specifications as the original 5H80689, ensuring a drop-in installation without wiring modifications.

Does this module work for both Natural Gas and Liquid Propane?
While this specific listing focuses on Natural Gas Ignition Controls, the board itself manages the ignition sequence. Always confirm your gas valve and orifice settings match the fuel type being utilized in the field.
