Honeywell 32001676-001 Board Assembly

The Honeywell 32001676-001 Board Assembly is the dedicated replacement printed wiring board specifically engineered for high-performance HE360 and HE365 series powered flow-through humidifiers. As a critical humidifier control board, it manages the synchronized operation of the 120V fan motor and the water solenoid valve. This OEM control circuit features an integrated transformer that steps down line voltage to 24VAC, providing the necessary power for the humidistat circuit and solenoid activation. Whether you are troubleshooting a Honeywell HE365 not working or performing a routine HVAC humidifier repair, this printed circuit board (PCB) ensures precise humidity regulation by processing signals from the humidistat to trigger moisture delivery. Built for durability in high-moisture environments, the 32001676-001 simplifies field replacement with clearly labeled terminal connections for E1-E10, allowing for rapid diagnostics of the power humidifier fan board and solenoid functionality without complex rewiring.

Key Benefits

• Direct Compatibility: Precision-engineered for seamless integration with HE360 and HE365 series models.
• Integrated Transformer: On-board conversion of 120VAC to 24VAC simplifies the electrical footprint and powers external controls.
• Optimized Solenoid Control: Ensures reliable water flow management by precisely switching the solenoid valve during call-for-humidity cycles.
• Robust Construction: Designed with high-grade copper traces and heat-resistant board material to withstand consistent furnace plenum temperatures.
• Efficient Diagnostics: Standardized terminal blocks allow technicians to quickly verify line voltage and 24V output during troubleshooting.

Common Questions

How do I know if the 32001676-001 board needs replacement?
If your HE360/HE365 fan doesn't spin and the solenoid fails to open despite 120V power at the source and a closed humidistat circuit, the board's internal relay or transformer has likely failed. Check for 24VAC at the solenoid terminals during a call for humidity.

Can I test the board before installation?
Yes. Experienced technicians can bench-test the assembly by applying 120VAC to the line voltage terminals and jumping the humidistat (yellow wires) together. If the relay clicks and the fan/solenoid outputs energize, the board is functional.

Does this board support automatic digital humidistats?
Yes, the board provides the 24VAC power supply required for automatic humidistat models like the H1008 series via the blue wire terminals.
