Re: Crack inside fridge
Yes, you need to worry about it.
Moisture will get in there, into the foam and cause what is known as an “insulation failure”, that is to say that the insulation will not be keeping in the cold air and keeping out the hot air as it should do. This will lead to extended running times and possibly a ball of ice in the fridge where there is no insulation from the moisture that builds up.
If it’s caught early enough there is a special sealant that can be used to repair it but I suspect that, at the age, that ship has long since sailed. 😉
How it’s handled by Whirlpool’s warranty I’ve no idea.
