Quick check — and when it's not DIY
There's one thing worth checking before you book anyone: check how often the door's been left open or ajar recently, since that's the single biggest cause of humid air getting in. When that isn't the fix, a genuinely failed defrost heater or timer needs the interior panel off to test and replace, and misdiagnosing it means paying for parts that weren't the problem.
