Stop: this involves gas or the sealed refrigerant system.

OnCall Tech only describes the symptom. Gas work needs a licensed gas technician, and refrigerant work requires EPA Section 608 certification. If you smell gas: shut off the supply if it is safe, do not switch anything on or off, ventilate, leave the building and call the gas utility.

OnCall Tech is a reference tool for trained technicians and can make mistakes. Always disconnect power and confirm with the manufacturer's documentation before you work.

Known issue: Whirlpool / Maytag / KitchenAid three-door French-door 'frost clog' (fresh food warm, freezer OK)

A class settlement (Paperno v. Whirlpool, N.D. Cal., final approval May 13, 2025) covered certain Whirlpool, Maytag and KitchenAid three-door French-door refrigerators built roughly 2012 to 2019 that may not fully defrost the fresh-food evaporator, so frost and ice block airflow and the fresh-food section stops cooling. Whirlpool denied wrongdoing. The settlement reimbursed documented evaporator repair or replacement costs within limits; reported claim deadlines were in 2025, so new claims are likely closed. The repeat-icing pattern is still common in the field.

Field pattern: fresh food warm, freezer fine (air damper stuck or iced shut before a sealed-system call)

On single-evaporator refrigerators the damper is the flap that lets freezer air into the fresh food section. If it freezes shut, sticks, or its motor or control fails, fresh food warms while the freezer stays cold. The wrong turn is calling it a refrigerant problem when the freezer is cold, or thawing the damper without fixing whatever put ice on it.

LG linear/inverter compressor fridge not cooling

Rule out demo mode, airflow, fans and defrost first, then use LG's forced-run diagnostic to see whether the compressor runs. If the compressor runs but doesn't cool, or won't start with a good board, it's a sealed-system failure: refer it to LG service or an EPA 608-certified technician and check the compressor warranty.
