Focus on the development, production and sale of range hoods and gas hobs.
ALK Product After-Sales Plan and Product Testing Overview
release time:
2026-04-03
This article covers ALK's 3-stage quality testing (gas cooktops, range hoods, ovens), overseas after-sales solutions (self-service, local repair, full replacement), 24-month warranty, and technical support.
Part I: Product Testing Showcase
Comprehensive Quality Inspection System
We operate a three-stage quality inspection system: incoming materials, in-process production, and final shipment.
Incoming materials: Core components (burners, valves, motors, heating elements, thermostats, and glass panels) undergo 100% parameter verification per AQL standards, ensuring a batch pass rate >99.5%.
In-process: First Article Inspection, line patrols, and pressure and leak tests per international safety standards (CE/GOST/CSA); assembly tolerance ≤0.1 mm.
Shipment: Full functional and visual inspection per CE, CB, RoHS, plus random drop and vibration tests — ensuring zero out-of-box defects and zero cosmetic flaws.
Core Testing Items
Gas cooktops: Live ignition test (pure blue flame, no anomalies); flame failure device cuts gas within 10 seconds; valve body tested >10,000 cycles without leakage.
Range hoods: Airflow, noise, and grease separation meet standards; tempered glass is impact-tested (1 kg steel ball)—no sharp edges if broken.
Electric ovens: Nine-point cavity temperature tolerance of ±10°C; door hinge tested for >20,000 cycles; outer glass temperature rise of ≤60°C; timer auto-off.
Whole-unit reliability: 72-hour burn-in at 40°C; vibration test per ASTM D4169.
Safety & compliance: Certification marks (CE, GS, CB, and RoHS) on the product/package; test reports on website; gas type compatibility provided.
Part II: Overseas After-Sales Solutions
Strategy 1: Pre-Sales Prevention & Installation Support
Confirm local gas type and pressure before ordering; the factory pre-installs correct nozzles. Nozzle conversion kits and instructions are available if the gas source changes. After delivery, users should unbox, inspect, take six-sided photos, and record a video. Users arrange local licensed installations. For electric ovens, confirm voltage/frequency match on the nameplate. Non-professional installation issues are not covered under warranty.
Strategy 2: Rapid Response & Remote Troubleshooting (Golden 48 Hours)
Contact via website, WhatsApp, WeChat, or email—response within 24 hours. Provide: serial number, installation environment photo, and short fault video (<10 sec) following product-specific guidelines (ignition, flame, gas odor, suction, heating, door issues, etc.).
Intelligent diagnosis:
Logistics damage → assist with freight insurance claim and replacement (based on unboxing video).
Installation error → provide corrective guidance.
Manufacturing defect → initiate after-sales process.
Improper use → send maintenance guidelines.
Strategy 3: Tiered After-Sales Resolution
Prioritize component replacement + local repairs; full-unit return not recommended.
Tier 1 – User self-service: Replace simple parts (ignition needles, thermocouples, knobs, burner caps, nozzles, control panels, bulbs, capacitors, filters, heating elements, temperature probes, door seals, etc.) using purchased parts and tutorials. No need to return old parts.
Tier 2 – Local repair: For motors, circuit boards, and valve assemblies, the user contacts a local technician; we provide remote guidance. In key markets (USA, Germany, France, UK, and Australia), users may access contracted service providers at their own expense.
Tier 3—Full unit replacement: Only for severe cases (completely nonfunctional upon arrival, structural deformation, spontaneous glass breakage, severe valve leakage, or heating system failure after multiple repairs). User returns defective unit (shipping at user’s cost). After verification, we cover replacement shipping. For built-in products already installed, prioritize local repair. If return/replacement is chosen, the user assumes all removal costs and risks.
DDP returns: User responsible for return shipping and customs clearance.
If the FAQ does not resolve the issue, contact us via the website, email, or WhatsApp.
Part III: After-Sales Policy Summary (for web display)
24-month warranty
Long-term consumable supply: Ignition needles, nozzles, sealing rings, filters, bulbs, etc.
Technical support: Damper adjustment, temperature calibration, cleaning/maintenance, firmware updates.
Safety commitment: If a manufacturing defect causes a gas leak or electrical fire (verified by a third party), we refund the product cost. Other consequential losses are not covered.
Minor operational issues: Provide illustrated guides; closed-loop resolution.
Component failures: Simple parts (ignition needles, bulbs, filters) — user replaces and submits video to close case. Complex failures (motors, circuit boards, valve assemblies) — user contacts local technician; we provide remote guidance.
