How to remove the disgusting smell due to the decay of the meat inside the refrigerator

http://techlife.samsung.com/ways-remove-odors-refrigerator-1045.html

I would not waste my time trying to fumigate something that carries carcinogenic fumes- especially when it comes to storing food products for human or even pet consumption.

I bet this freezer is over 10-years old and would not be worth running anyway, due to its poor energy rating and high consumption of electricity.

The time and money that would need to be invested in purifying this junky freezer (which is why the previous owner got rid of it) and by-the-way, there's no guarantee that after putting good money into bad, that fumigating it would be successful, if I were you, I would strip it down for its scrap metal (which is a profitable commodity) and go collect the money instead of spending it.

Please, please, please- by all means- remove the door(s) from the freezer so no child gets locked in and suffocates if it is to be abandoned or unattended.

I know this might sound weird but there might be a dead rodent or other small animal under the fridge or squeezed in between small parts. This happened to us but it was not the fridge; it was the air-conditioning unit. If this has happened in your case, the smell will be really bad for a while and eventually go away when the animal has fully decayed.
Even if it is not a dead mouse, here is a good website that gives you the names of effective odour neutralising products. It's definitely worth having a look at. http://togetridofmice.com/2009/12/dead-mice-smell-dead-rat-smell.html
Good luck.

Cleaning would not get rid of the smell, just place a piece of charcoal in the fridge and it will remove the smell in due time.

Hope it helps.

You may have had something drip and somehow get under the fridge. I know blood dripping from meat will smell. It could have dripped down through the defrost drain tube to the pan underneath. You can access the pan from the rear by removing the cardboard cover. If the smell seems to be coming from the pan, it's difficult to remove so I would just pour some bleach in it to kill any smell and you may can wipe it out from there. The drain tube may also have the smell in it so you can pour some bleach into it from the inside of the freezer at the bottom of the rear panel. You can move the fridge to see if anything is pooled on the floor that might smell.

Check the defrost water evaporator tray located inside the bottom grille. You probably will find a disgusting mess. Remove the tray and scrub it clean to resolve the problem. While you are cleaning up, check the tube that directs defrost water into the tray. It may be clogged.

Keeping baking soda in the freezer has little chance of actually absorbing any odor causing air because the air is too dense. Two solutions I can recommend is to either turn the freezer to its HIGHEST setting so it doesn't freeze anything and try the baking soda again, or the second is very inconvenient, but I've seen it work, is to unplug the unit and place a container of Damp Rid in it for a couple of days.

Check the inside of the freezer and ensure there are no cracks in the lining as moisture can get in there and cause horrible smells, especially if you have ever put meat (especially poultry) and the package leaked before freezing.

use a syringe to blow clorine bleach down the drain hole.(the clorine will gas off and leave no smell after about an hour)

The drain is at the bottom inside the freezer section. It is possible a piece of something got behind a panel, or otherwise in a "hidden" spot. Or something is in the defrost water tray underneath and every time it defrosts, it gets wet and releases the odor again. Look in the drain pan by removing the kick plate (bottom grate under the doors) and look to see if anything is there. Use a few open boxes of baking soda in the fridge (to absorb odors), and wipe the inside with some vanilla extract. that combination will help with the odor. But the source of the odor needs to be removed first. It sometimes can be hard to find.

I've not seen this before. I'm wondering if some food (meat/meat juice) has gotten behind the rear panel of the freezer. The only way to find out is to remove the rear panel to inspect it. You'll have to remove all the food and remove all the shelves and bins. You'll see 6 screws on the rear panel, remove these. Grasp the vent (at the bottom) with needle nose pliers, lift up and out then down. Now pull the panel out by lifting it over the top shelf supports. This will expose the evaporator coils so you can see if there's anything in there causing the bad smell.

If you don't find anything... try some baking soda?
