The motor-unit must be replaced after 5 years or 160,000 cycles, whichever comes first. Verbatim source: VanDOOR AluLIFT maintenance manual v03-2026 §5.1 — “Replace the motor-unit after 5 years or 160.000 cycles”. On the basis of 40 cycles/day × 5 days/week (~10,000 cycles/year), 160,000 cycles equate to about 16 theoretical years — the 5-year threshold therefore becomes the limiting criterion at standard usage. At heavier usage, anticipate the replacement on the cycle counter.

High-frequency consumables: DL-8001254 guiding blocks — set of 4 per system per year; A23 12V batteries for FOB remote — 1 to 2/year per FOB. Fatigue parts to anticipate: DL-8001252 drive gear — replacement every 5 years or 160,000 cycles; AluLIFT balancer — every 1.5 to 2 years. Incident-critical parts: emergency-release cable, 30 A fuse, 2.5 m battery cable. The full motor block is replaced at end-of-system-life (16 years theoretical at standard usage).

Parts common to both ranges: motor block, control box, REED limit-switch sensors, FOB remote and A23 battery, battery cable, profile cable, 30 A fuse, DL-8001254 blocks, DL-8001252 drive gear, release key and cylinder. AluLIFT-specific parts: 5 push-button references (DL-8000810/811/814/815/816), spring balancer, door panels, vertical and horizontal rails, cable drums. Note: in EN documentation the drive gear is listed as DL-8002152 — confirm with VanDOOR (likely typo, correct reference is DL-8001252).
