To continoue with my Engel upright fridge performance issues, I took on board suggestion from Edz,
" Could you fit a couple of computer fan to help circulate the cold air from the freezer ..
I take it thats the only part that supplies the cooling for the lower section of the fridge like most small uprights .. Guess you have made sure the door seals are in very good condition and the door closes tightly ."
After installing a small case fan below freezer box,temperature minimum gain was down to 9 degrees. On checking exterior ventilation space I noted a similiar case fan = part of the manufacturers package that blows over the exterior condensor,and this was working well! I also found a 240V plug & lead,so I connected to mains supply & noted a change in "tone"of the compressor running (eg.stronger-bit louder). I have left this running for 24 hours (temps outside at 45 degrees!) with new interior fan going also.Result this morning is 4.6 degrees which I am happy with.
Question now is,with a better performance from 240V supply over the 12V supply, would it be worth while upgrading original 12V wiring? My slide on is a yankee Palamino with the wiring standard equivelant of a "Jayco" - white & black cables! Is it worthwhile upgrading to 6 - 8 B&S? cable run direct to battery is approx 3.5 metres, original run is anyones guess with it coming from a factory install fuse box.The original fridge was a 3 way Thetford, & have found this Engel is a 2016 manufacture.
Thanks ,Steve.
