Turn it off. If you keep running it, it will die completely fairly soon. Please feel free to jump to the end if you don't want a fridge science lecture - it might help you figure out the problem though. When a fridge/freezer runs, the condenser (all the tubes at the back) will get warm-hot. That is where the heat goes from inside the fridge. First thing to check; is there excessive heat to remove from the fridge/freezer? Check the door seals are ok - cold air falling out of a bad door seal can make a fridge both cool and warm a room at the same time - which obviously leads to problems Check that the lights inside actually go off when you close the door by pressing the switch that the door usually presses when it shuts, and checking that the door will press the switch as far as it needs to go. Second thing; Check that there is adequate ventilation at the back - remember the ideal situation technically for a fridge is to have the bit at the back outside the house in the shade like an air-con unit. pull the fridge a bit more away from the wall and try blowing a fan onto it. Clean gently with a soft brush any dust etc that is on all the tubes at the back - it can cause an insulating coat to form. If the dust is sticky and hard to shift, then gently use a soft paintbrush and warm soapy water. Third thing; When the amount of refrigerant gas in a fridge system is getting low (they all leak a tiny bit all the time - even without any fault) two main things happen: The fridge gas has a lubricant mixed in with it that keeps the inside parts of the system oiled. when the gas is low, so is the oil and you get the same effect as running a car with no oil - runs hot, then dies. The low gas has an effect inside and outside the fridge - inside, near where the gas first enters the evaporator (the plate in the fridge that gets cold) it will get extra cold. the compressed refrigerant evaporates too quickly - easy way to explain is that there is nothing in front of it in the queue so it runs through too quick. the same thing happens in reverse when the gas goes into the condenser at the back, the gas condenses too quickly making the back very hot. I think, from what you say, that low gas is the problem. Although it is not too complicated, it is illegal for you to do it yourself in most places for environmental and safety reasons - get any fridge repair guy and he can do it and check for leaks at the same time. Hope this helps, and is in time to save your fridge :)

A certain amount of heating on the outside is normal (fridges and freezers are effectively an insulated box connected to a heat pump - and the heat has to be pumped to somewhere). If the external heat is getting excessive, you need to consider three possibilities (in order of increasing hassle and expense) 1. Make sure the heat has somewhere to go - ensure there is room for air to circulate around the outside of the fridge and that it isn't sited in front of a radiator (or in a sauna!) 2. Check the doors are properly shut and the seals are OK (because the plant will have to work much harder if the cold air inside is continually getting replaced with warm (note also that the plant in domestic fridges/freezers is sized on the assumption that the door will stay shut most of the time - causing problems when you use them in a commercial environment where the door is continually being opened). Depending on ambient humidity, one clue that you're getting outside air past the door seal might be excessive frosting inside. 3. If neither of the above, the plant may be losing efficiency (perhaps due to a slow leak of refrigerant). You need to monitor the situation carefully as when it comes, the decline into failure to maintain proper cold levels inside tends to come quite suddenly. Investigation and repair needs the right equipment and is usually a job for a pro - get a quote and compare with the cost of a new unit before commiting to anything. A.

If it is running well there is nothing wrong with the fridge. It is supposed to get hot at the back as that is the radiator. If it wernt hot, then you worry. Heat on the sides is normal as those are your mullon heaters used to stop moisture.

Why is the outside of the fridge hot


A fridge works by creating a convection current by drawing all the heat out of the air in the fridge and transferring it out if the back, this can mean the back of a fridge can feel warm/hot to touch. If you are genuinely concerned about the safety of the product however you should contact the manufacturer and stop using the product.

Burning electrical smell, refrigerator hot at lt side (freezer side) and at center area between doors


When you smelt this was the fan in freezer off? If so it is most likely in defrost mode and the smell is from frost melting and hitting the heater in the freezer. The hot on the sides and in the center. Is this outside the box? If so this is normal. There are coils inside the frame of a fridge that stay warm to eliminate condensation. Sometimes they shift and get too close to the wall and thats what you are feeling.

If you have any further questions please feel free to contact.

My roper side by side is getting hot


Depending on where your fridge is getting hot, this could be a normal operation of your fridge. if your feeling heat on the outside or in between the freezer and fridge this is normal due to the heating element inside the walls of your fridge. this heater is ther to eliminate any condensation that may occur inside the walls and insulation of the fridge. if you are getting a large amount of heat coming from the back of the fridge this could indicate that the compressor may be on the way out, and constantly running.hope this helps.

Thanks

I have the Lg fridge model LSC26905TT side by side. There is a humming noise-that we never heard before-along with the freezer side on the outside is very hot, and the middle section on the inside where...


Okay, the heat you're feeling is normal. That's the door heaters doing their job. Without them, you'd have condensation building up in those areas and water all over the floor. Unless you can smell something cooking from those or, they stop working, they'll be okay. Most likely it has something to do with the humming which I will address now.
The condenser is probably plugged with dirt. This will cause the compressor to work harder and make that humming noise. Because it can't remove the heat as well (from being plugged), the cabinet is heating up in those areas you mention beyond their normal temperature.
Clean that condenser and see if that helps. It must be free of all obstructions to work properly.
Worst case scenario. If the condenser is clean, the compressor might have gone bad.

The outside middle front & left hand side of the fridge were hot


The reason you feel heat by the middle of the door is because of the "mullion heater' or anti-sweat.
Check the temperature of the freezer, must be below 12*F for the ice maker to work.
