Scope of Repair
Elevator Boards We Repair
We perform component-level diagnostics and repair on the electronic assemblies that control elevator operation — from main controller logic boards to individual hall call cards.
Main Controller Boards
CPU and logic boards governing overall elevator operation, dispatching, and safety interlocks.
Drive / Inverter Boards
Variable-frequency drive boards for both hydraulic and traction elevator motor control systems.
Safety Relay Boards
Safety circuit boards and relay logic assemblies — tested against original specifications after repair.
Door Operator Controller Boards
Electronic controllers for car and hoistway door operator systems including reopening and timing logic.
Car Operating Panel (COP) Boards
In-car button and display boards, including floor selection, door open/close, and emergency circuits.
Hall Call Boards
Floor-level call button interface boards for landing stations, including indicator and communication logic.
Dispatch System Boards
Group dispatching and supervisory controller cards for multi-car elevator installations.
Leveling / Position Sensor Boards
Electronic boards that process floor-level sensing, shaft encoding, and positioning signals.

Fault Diagnosis
Common Elevator Board Failures We Diagnose
Our technicians identify root-cause failures at the component level — not just the symptom.
Controller Fault / No-Run Condition
Main logic board failures causing the elevator to remain out of service. Often traced to failed microprocessors, corrupted memory, or power regulation components.
Drive Fault — Inverter Failure
Drive board faults typically caused by failed IGBTs, capacitor degradation, or gate driver circuit failures in the motor control section.
Safety Circuit Fault
Safety relay board failures that prevent the elevator from running. We test all outputs against original safety specifications after repair.
Door Operator Fault
Door controller board failures causing doors to open/close erratically, fail to open, or generate continuous door fault codes at the main controller.
Communication Error — Car to Controller
Serial or CAN bus communication failures between car operating panel, hall call boards, and the main controller causing intermittent or full-loss-of-service conditions.
Leveling Fault
Sensor interface board failures causing mis-leveling, floor hunting, or leveling faults — often related to signal conditioning circuits or failed optocouplers.
How It Works
Our Repair Process
Receive & Log the Board
We log your board upon arrival, confirm the part number and system information you provide, and assign a repair order.
Visual & Component Inspection
Full visual inspection for burned components, failed capacitors, cracked traces, corroded connectors, and physical damage before powering the board.
Circuit-Level Diagnosis
Powered and in-circuit testing to isolate faults. Safety relay boards are verified against original switching specifications and safety circuit logic.
Repair & Component Replacement
Failed components are replaced with equivalent or upgraded parts. Solder joints are re-flowed, connectors cleaned, and boards cleaned of contamination.
Functional Test & Ship with Warranty
The repaired board is functionally tested under load conditions. Shipped back with a 12-month warranty covering the repair performed.
Electronics Repair Only
Flexa Systems is not a licensed elevator contractor. We repair the electronic boards and control modules only. All installation, commissioning, adjustment, and testing in the field must be performed by a licensed elevator technician in accordance with ASME A17.1 Safety Code for Elevators and Escalators and applicable local jurisdiction requirements. Our repair restores the board to its original electronic function — it does not alter, re-engineer, or re-certify the elevator system.
Cost Comparison
Why Repair Instead of Replace?
New OEM elevator controller boards are among the most expensive boards we see. For older systems, replacements may simply not exist.
New OEM Controller Board
$2,000–$12,000+
When available — lead times of 6–16 weeks common for major brands
Pre-2000 / Legacy Systems
Discontinued
OEM replacement boards no longer manufactured; new controller installation required if board cannot be repaired

FAQ
Frequently Asked Questions
Do you repair elevator safety relay boards?
Yes. We repair safety relay boards at the component level. After repair, we verify relay switching function, contact integrity, and output logic against the original board specifications. All reinstallation and final commissioning testing in the elevator shaft must be performed by a licensed elevator technician per ASME A17.1 requirements.
Does repairing the board affect code compliance?
Our repair restores the board to its original electronic function without modifying its design, programming, or safety logic. We do not alter the controller's behavior. Code compliance of the overall elevator system remains the responsibility of the licensed elevator contractor performing installation and inspection.
What is your turnaround time for elevator board repair?
Standard turnaround is 3–7 business days from receipt. Rush service (1–2 business days) is available for an additional charge. We understand that a failed elevator board means an elevator out of service, and we treat these jobs with priority. Contact us to discuss your timeline before shipping.
What information do I need to provide when sending a board?
Include the elevator manufacturer and model, controller model number, board part number (from label on the board if visible), and a description of the fault or symptom observed before removal. Any fault codes from the controller display are also helpful. This information allows us to reference the correct specifications during testing.
Do you reparametrize or reprogram drive boards after repair?
We repair the drive board hardware. If parameter memory is intact, the existing parameters are preserved through the repair process. If the parameter memory (EEPROM) has been corrupted or lost, we will advise you. Reparametrization of the drive for the specific elevator installation must be performed by the elevator technician on-site during commissioning.
Send Your Board for a Free Evaluation
No commitment required. We evaluate your elevator board at no charge and provide a repair quote before any work begins. If we cannot repair it, you pay nothing.
