If it is the new fridge that is going bad, is it a fire hazard? I left power to it and won't return till the weekend.
This is what I was suggesting earlier, the old frig probably leaked the ammonia out and is now absorbed into the wood. However, I am not sure how long ammonia would smell once evaporated. I am guessing it would last. I would get some "natures miracle" Nature's Miracle Just For Cats Urine Destroyer - Nature's Miracle Sale - Featured Products - PetSmart
but in a smaller bottle and spray it on the wood a few times, or as another suggested a 2 to 1 mix of vinegar and water and spray on the wood. and see if it helps. If not buy a quart of Kilz primer or some other type of a wood cover that would trap that smell in. Lowe's or the such should be very able to show you a product that will work. They have stuff you can paint on a sub floor of your house to cover pet odors with., this is what you would look for.
