Quick check — and when it's not DIY
Before booking a repair, check how often the door's been left open or ajar recently, since that's the single biggest cause of humid air getting in. Also, check the door seal for gaps and make sure vents inside aren't blocked — the most common self-fixable cause. If none of that changes anything, if ice keeps building back up, the defrost heater, timer, or sensor has failed, and reaching those parts means removing interior panels without damaging the liner.
