When a drive overheats, trips on a fault, or causes the car to hunt between floors, you need electrical expertise—not just a mechanical tune-up. We help building teams across Canada sort drive and motor problems on traction units and modern MRL gear. Error codes, hot smells from the cabinet, and faults that only appear after a long run are all useful clues. Share them when you call. We send technicians who can work safely inside the controller and drive, test under load, and leave you with a plain summary of what failed. We do not endorse bypassing safeties to “keep the building running.” If passengers are trapped, call the emergency line at 1-888-892-0457 instead.
Why drive faults need a specialist desk
Drives interact with encoders, motor windings, and software limits. A mechanical-only visit may replace unrelated parts while heat damage continues in the cabinet.
This desk exists so your building gets electrical troubleshooting first, then mechanical follow-up if rollers or guides contributed to the symptom.
Drive symptoms worth documenting
Error codes referencing inverter, OL, or DC bus. Hot smells from the drive cabinet. Intermittent faults only after long runs. Noise changes that coincide with acceleration.
Photos of nameplates and ventilation filters help us bring compatible spares on the first visit when possible.
Testing after drive repair
Load tests across the travel height, not only one floor. Verification that regenerative energy is handled without nuisance trips. Confirmation that door interlocks still open only when permitted.
We log parameters changed so future contractors understand the baseline.

Common questions — Canada
Is drive repair always cheaper than replacement?
Not always. When capacitors, heat sinks, or boards are obsolete, we explain modernization options with rough timelines before you commit.
Can a mechanical technician fix my drive?
Drive faults require electrical qualifications. We match skill set during dispatch rather than sending the nearest mechanical-only resource.
Will drive work require an outage for the whole building?
Often one bank can be isolated, but fire service and egress plans matter. We discuss tenant communication before lockout.
