Self-Install vs Manufacturer Warranty — Dispute Avoidance
Likely causes
Korean OEM warranty = certified installer required
Check: **Major OEM install certification**: ① **LG** = 'LG System AC Registered Installer' license (5-yr install card, certified receipt required). ② **Samsung** = 'Samsung Certified Installer' registration (e-tax invoice required, Samsung code signed). ③ **Carrier** = self-install allowed but warranty drops to 1-yr body only (no 5-yr compressor). ④ **Imports (Daikin, Mitsubishi)** = only Korean branch-certified installers covered. **Unqualified install result**: ① Compressor damage = no free repair (₩500k-1M self-pay). ② System leak = not covered. ③ 1-yr body warranty kept (Korean Consumer Basic Act).
What to do: **Tech self-protection**: ① Pre-install consent: 'Certified install = OEM 5-yr warranty kept' signed agreement. ② After install, register OEM service receipt + cert code (LG 'Install Register', Samsung 'Install Report'). ③ Give customer OEM warranty photo + install receipt copy immediately. ④ Dispute: install receipt + register code = strongest evidence. **Self-install dissuasion script**: 'Self-install voids compressor/system 5-yr warranty. You may pay ₩500k-1M out-of-pocket' → customer signs after decision.
Korea appliance warranty disputes = 8,000/yr via Consumer Agency/Fair Trade Commission. 'Certified install' confirmation = decisive evidence in 90% of disputes. LG/Samsung install registration = instantly via mobile app on-site (camera cert). New tech = OEM dealer registration = HQ training (3 days, ~₩300k, annual renewal). Customers insisting on self-install = 90% dispute after 1 year. Dissuade firmly, get signature, take photos = self-protection mandatory.
