# Porch notes

> Short notes on what actually fails here, written after the call rather than before it.

- Why Ice Cubes Come Out Hollow (/porch-notes/hollow-ice-cubes/): A hollow cube is a water problem wearing a temperature problem's clothes. Here is how to tell the two apart before you call anyone.
- Frost on the Back Wall of the Freezer (/porch-notes/back-wall-frost/): Frost is not the freezer being too cold. It is humidity that entered the cabinet and then failed to be removed on the next defrost.
- Condensation Along the Door Line (/porch-notes/door-seal-condensation/): A seal fails slowly and invisibly. Long before it lets go, it is letting in humid air, and the cabinet is paying for it in compressor hours.
- The Condenser Is Above the Doors, Not Below (/porch-notes/condenser-under-the-grille/): The one piece of maintenance that reliably extends the life of a compressor, and the first thing we check on any cabinet that never stops running.
- After the Power Blinks, and What to Check (/porch-notes/storms-and-control-boards/): A dark panel does not always mean a dead board. The useful first question is whether the compartment is still holding temperature.
