Description
Product Introduction & Engineering Value
A failed controller board inside an automatic door operator can create a misleading troubleshooting situation. The motor, sensors, and mechanical assembly may appear normal while the actual fault originates in the control electronics.
The NABCO FKC-107-01 is a legacy control PCB used for NABCO automatic door systems. For replacement projects, engineers should verify the complete board marking, connector arrangement, installed operator model, and firmware or revision information before installation. NABCO continues to support various automatic door product families through its service and maintenance network, while older boards may require careful identification.
Technical Specifications
Identification Parameters
- Manufacturer: NABCO
- Part Number: FKC-107-01
- Component Type: Printed Circuit Board Assembly
- Control Category: Automatic door controller electronics
- Application: NABCO automatic door operators
- Board Function: Signal processing and actuator control interface
- Replacement Class: Legacy control PCB
- Market Availability: New open box / surplus listings reported
- Installation Form: Internal controller board replacement
- Verification Requirement: Match board revision and connector layout before installation
⚠️ Note: Publicly available documentation for FKC-107-01 does not provide a complete electrical datasheet, I/O map, voltage specification, or firmware compatibility matrix. Final compatibility should be confirmed from the installed equipment documentation and board markings.
Field Application & the “Trench” Experience
A building maintenance team manages a high-traffic entrance fitted with an older NABCO automatic door system. The door begins stopping randomly. Technicians first replace the sensor and check the motor assembly. The fault remains.
The experienced technician checks the controller cabinet.
The FKC-107-01 PCB shows signs of aging: intermittent relay operation, unstable signal processing, and heat-related component deterioration. Instead of replacing the entire door operator assembly, the maintenance team sources a matching FKC-107-01 board and compares every identification mark before installation.
That comparison prevents a common mistake: installing a similar-looking NABCO board designed for another operator generation.
Specific application scenarios
- Commercial building entrance door maintenance — restoring legacy automatic door operators without complete system replacement.
- Hospital and public facility access doors — maintaining reliable opening/closing control systems.
- Industrial personnel access doors — replacing controller electronics in older NABCO automatic door installations.

Transparency SOP: QA & Testing
A proper FKC-107-01 inspection process should include:
- Visual condition check
- PCB surface inspection
- Connector condition
- Solder joint inspection
- Signs of corrosion or contamination
- Identification verification
- Confirm marking
- Record revision labels
- Photograph component side and solder side
- Electrical checks
- Continuity verification
- Power input inspection
- Component-level examination
- Functional assessment
- Where the correct NABCO operator test environment is available, verify controller behavior with compatible equipment.
A clean-looking PCB is not automatically a tested PCB. For legacy control boards, traceability matters.
The Veteran’s Tech Trap Guide
⚠️ Trap #1 — Matching only the PCB number
The marking is important, but it is not the only compatibility factor. Confirm the automatic door operator model, connector layout, and revision information.
⚠️ Trap #2 — Ignoring stored configuration
Some automatic door controller systems contain setup parameters related to opening speed, closing force, sensor timing, and safety inputs. Replacing the board may require reconfiguration.
⚠️ Trap #3 — Treating surplus stock as plug-and-play
A surplus PCB may have been stored for years. Check for oxidation, capacitor condition, connector wear, and environmental storage conditions before installation.
PRO TIP: Before removing the original , photograph all connectors and adjustment settings. Legacy equipment often has undocumented field adjustments that are difficult to reconstruct later.
Dynamic FAQ
What is NABCO ?
The is identified as a NABCO printed circuit board assembly used in automatic door control equipment.
Is still an active NABCO production part?
Public availability appears limited, with examples appearing through secondary-market surplus channels. Confirm current OEM support status before planning long-term maintenance strategy.
How do I confirm compatibility before ordering?
Provide:
- Existing PCB part number
- Board revision marking
- Automatic door operator model
- Connector photos
- Complete equipment nameplate information
Can I replace the PCB without adjustment?
Not always. Depending on the automatic door system, controller replacement may require parameter verification, safety-input checks, and operational adjustment after installation.
What should be checked on New Surplus stock?
Request:
- Actual board photographs
- PCB label confirmation
- Storage condition information
- Functional test details
- Warranty terms
What warranty should apply?
Warranty depends on supplier and condition classification. Confirm whether the board is New Surplus, Used, or Refurbished and whether functional testing has been completed before purchase.
Procurement Recommendation: For NABCO , maintain the spare-parts record using the full identifier + operator model + revision information. For legacy building automation equipment, the surrounding system information is often as important as the PCB number itself.
