Visible surfaces can thaw before ice in concealed areas has cleared. A short shutdown may change the symptom without completing the model's prescribed process.
What the observation tells you
That can lead to rapid recurrence and repeated disruption of both food compartments. Do not remove fixed panels to speed the process or use a heater to reach hidden ice. The underlying cause also remains unconfirmed even after a full thaw.
A useful next step
Follow the exact owner procedure with suitable food storage. Record how long the shutdown lasted and where ice returns. Persistent recurrence warrants assessment rather than a cycle of improvised short defrosts.
