Honeywell 4074EHG Repair Kit

The Honeywell 4074EHG Terminal Board Repair Kit is a critical service component used for the FC37A electronic air cleaner cell. This OEM terminal board assembly is specifically engineered to restore electrical integrity when the original contact points have suffered from arcing or terminal burn-in. The 4074EHG is a direct replacement and is functionally identical to the 4074EHG/U model, ensuring a precise fit within existing Honeywell Residential air filtration systems.

For technicians in the field, this FC37A repair kit provides a strategic solution for arcing issues. By mounting the replacement collector cell contact board on the opposite end of the cell frame, you can bypass burnt plate edges and establish a fresh electrical connection. Each kit includes a high-grade terminal board, two interface connector clips, four aluminum pop rivets, and a replacement cell handle to facilitate proper realignment and airflow orientation. Using this Honeywell air cleaner part maintains factory-spec high-voltage distribution between ionizing wires and collector plates.

• Optimized Conductivity: Restores factory-spec voltage distribution to eliminate electronic air cleaner arcing and snapping sounds.
• Comprehensive Hardware: Includes necessary rivets and clips to complete a field-level rebuild of FC37A collector cells.
• Dual Compatibility: Fully interchangeable with the Honeywell 4074EHG/U for streamlined inventory management.
• Strategic Mounting: Allows for installation on the non-damaged side of the cell to extend the service life of expensive internal components.

Is the 4074EHG compatible with older FC37 series cells?
Yes, it is specifically designed for the FC37A and B series cells. It allows you to relocate the terminal connection to the clean end of the cell if the current terminal side is damaged.

Why does the kit include a new cell handle?
When the terminal board is moved to the opposite end of the cell to avoid burnt edges, the handle must also be moved so the cell can be inserted correctly into the cabinet with the proper airflow orientation.

What tools are required for this repair?
A veteran technician should have a 1/8-inch (3mm) drill bit to remove old rivets and a standard pop rivet tool to secure the new terminal board assembly.
