dometic frig

[emma8]

We have a 2008 Sundance 3200ES with a dometic frig. Noticed today that there is a fine hairline crack on wall inside of frig. Will this affect operation of frig in future - seems to be working ok right at this moment. Wondering if this can be fixed by applying a fine coating of silicone caulking over crack. Would appreciate any information you can provide to remendy situation and why this could possibly have happened in first place.
Tk you.

emma8, If I had to guess, I would say a temporary seal of silicone will keep the cool in the fridge but it sounds like something that should be replaced. Dometic carries a 3 year parts and 2 year labor warranty from the in service date. If you could, please post a few pictures of the crack. Thanks!
