I am currently visiting a relative who lives in Spain but not on the mainland. She has an LG Model GRA2076ROM "amercian"style fridge freezer whicxh is about 5 years old. Anyway she tells me it has died and had been making loud noises for a while. On checking it was showing Er code Dh. I didnt have access to manual or service info at that time but took the back out of the freezer innards to reveal a heavily frosted freezer matrix which seems so have obstructed the dc fan,causing it to jam,a blade to snap off and the motor bearings to fail. The motor looks poorly designed and cheap anyway !
So...as a start,i managed to obtain a new motor and fan blade,did a full defrost and it seemd to work but Dh code came back.
The compressor goes on/off as expected so im assuming it is still maintaining temeprature.
I now read that Dh is related to the defrost heater sensor. This sounds expensive to fix and the local spares shop is rubbish and not really co-operative. All they want to do really is send their man to fix and charge lots of money. People just dont do diy here!
So assuming its still maintaining temp as it appears to be..are these viable options?
1)Manually dderost say once a month in the pold fashioned way
2)Fit a mechanical plug in timer and set it to say,ppower off for maybe 1 hour in every 24 hours to defrost in this way?
