Lift faults FAQ
What is lift fault finding?
Lift fault finding is the diagnostic process used by lift engineers to identify the root cause of a fault before repair.
Why is the lift emergency phone not working?
Autodialler or emergency phone faults can be caused by handset issues, line failures, or control faults. We test the system and restore compliance.
Why do lift doors stop closing?
Door operator faults, safety edges, or alignment problems can prevent doors from closing. We diagnose and repair the door gear and controls.
What causes lift levelling issues?
Levelling problems can be caused by worn components, misalignment, or control settings. A lift engineer will diagnose and correct the issue.
Do you cover intercom faults?
Yes. We diagnose lift intercom faults and cab communication issues as part of our fault finding service.
