The garage fridge hasn’t been cold for a couple of months. Finally got high enough on the priority list to take a look. Findings: very dusty coils, and the fan in the freezer compartment wasn’t turning on its own.

Vacuumed out the coils, but need a swiffer duster wand to really get back in there.

Lubricated the fan and it seems to be able to come on under its own power. Letting it run for a while to see though.
