Does it smell of rubber behind the refrigerator?
Detail
New products may smell of rubber.
Rubber is attached to prevent noise from the compressor and
smell of rubber can occur due to heat generated by the compressor.
In particular, smell can be strong when the product is used for the first time
as compressor runs for a long time.
How to fix
Smell will eventually disappear within 1 to 2 months of use.
