There is a little yellow residue around the the bottom of a cylinder that has insulation and tubing inside. Also the freezer doesn’t get cold at all and the front display works and is flashing a code that according to my manual means the unit has failed not owner serviceable. I’m not getting a good feeling about this
That is dried up sodium chromate (rust inhibitor in the coolant)
It is toxic.....work it wet
No blowing with compressed air, vacuuming, brushing etc that can cause 'dust'
Face mask, gloves....spray bottle......work it wet to clean up before you remove/work on cooling unit
