Damage to RV from refrigerator drain hose

I just recently opened mine up (Norcold). It goes to a cup in the outside compartment. The end was closed from excess heat and not draining.



Before I opened this up, I was defrosting the fridge every 2 weeks. Now, it's been a month and I'm not looking at defrosting for another week at least, maybe not until we get home first week of May.
