My Freezer has six settings 1 to 6. As near is Ice build up along the door, I guess i need to lift up one of the six settings. I would be grateful for some guidance or guidance on when to raise the Settings. It is perceptible outside the door ledge on the Top. Do I lift up the setting or lower it? The Ice build up is removed regularly but in a event of Days The Build up of ICE is back. Is this bad habit so serious that I must get rid of an otherwise angelic Freezer.? I have tried adjectives Trouble-shoot applications remembered by a former school tutor
Answers:    if the ice is on the inside of the feezer near are a number of reason this can happen cause can be a faulty door trademark allowing the heat to seize in and condense this can bring a build up around the inside of the door.
Faulty insulation can cause rime outside the cabinet. if this is the case afterwards there is not profusely u can do about it
if nearby is large rime mound inside or even outside behind the cabinet and otherparts of the freezer are not freezing afterwards you may have a blockage of the system which is again not worth fixing.
Lets hope it is singular the door seal you cancheck this visually to build sure there is no gap alowing ot air to enter the freezer
no you don't want to get rid of it. we enjoy the same problem beside ours. its always freezing and sometimes when we start the fridge the water drips out. the best of the bleak settings is 3. hope this helps within some way.
