Check there are no small vegetables stuck in the seal. Crazy, I know, but it's amazing the places frozen peas can end up.
If there's nothing caught in the seal, perhaps the seal has deformed. How did you do the defrosting? Sometimes people use knives and damage parts of their freezer. Some people use boiling water, which can cause damage to seals. If the seal has become deformed, you will most likely need a new seal.
It might also be worth checking the door hinges; if the door isn't flush with the opening, the seal won't seal properly. Defrosting shouldn't cause any problems with the door, but sometimes accidents happen.
