Set cutoff on 419 to 38F with a dif of 1 and ASD of 12 min. Had the probe in a glass of water for thermal shock
It worked fine for about a month, getting me down to 36-38, then the temp started creeping up to low 40s then 50s with a fairly good layer of frost on the back wall of the freezer section, so I unplugged everything thinking the evaporator was frozen and needed a defrost. Didn't get much in term of water coming out anywhere.
Plugged back in after letting it sit about 24 hours. Figured the open cup of water might have been contributing moisture so removed it and have the probe hanging over my regulator dangling in air near (but not touching) the freezer wall and after about 30 hours it is reading 47 and constantly running so far. I put a computer fan in to circulate the air and added a canister of damp rid as well try try to mitigate the frost build up. No joy. Still frosting up on the back wall and (so far) only getting to mid 40s
Thanks for the help
