Quick check — and when it's not DIY
The one self-check that's actually worth your time: confirm the thermostat setting, that the door seals fully, and that vents inside aren't blocked by over-packed items. When that isn't the fix, a fan that's confirmed dead, or ice built up around it, means removing interior panels to reach it — not a quick swap without disassembly experience.
