Mitsubishi MR 560X. Top shelf of freezer not freezing food. Vents have been icing up. Fridge appears to be running too warm, around 11degrees Celsius. I have turned off fridge and defrosted it for 24 hours. Checked door seals ok. Problem unresolved. Any ideas?

are the shelves the part that freezes the food in your model/ What is the model number of your fridge?

Your description sounds like a loss of air flow problem. Check for overloading your freezer and fresh food side. In order for the freezer and fresh food side to work properly, the air vents need adequate room for air to circulate. I had a customer who completey filled the middle shelf with cardboard boxes and completely blocked air flow on the middle shelf The lower level near the evaporator was extremely cold and the upper area was room temperature in the freezer. Each shelf needs about an inch of room at the back and room between packaging to allow air to circulate.
Hope this helps

is the fan not working in it..may be jammed up..we had an old unit that did this all the time.. the door seal was bad allowing house humidity inside and it wpuld frost up so bad the fan got stuck..we eventually bought another used unit..

this fan needs to run when the compressor runs,check fan blade for being jammed by ice if you have this much ice on back wall as ice will stall motor,if no fan there will be no cool air to refrige compartment also the defrost drain tray will fill with water then freeze over which in turn floods the freezer floor and refrige compartments cause it cannot drain to the pan in the bottom

Make sure the two vents from the top of the fridge that run into the freezer are not blocked or obstructed in anyway, that's what the problem was in ours. Also do not allow ice to build up on the vents in the freezer.

Hi,

Fan problem is one of the most common reasons for the freezer to start failing, this is called "frost free failure." Ice can build up on the evaporator coils over time, and this ice builds up until it starts blocking the fan. The fan is responsible for circulating cold air throughout the freezer, so if it is blocked the freezer will not be able to freeze any food. You can usually check this by removing an access panel in the back of the freezer to inspect the coils. If ice is built up on the coils, a hairdryer can assist in defrosting them.

It's also possible that the fan is not running at all. If the fan is burned out or the motor isn't running, cold air can't circulate through the freezer and everything will melt. You can normally hear the fan motor switch on and off from time to time. Listen for it and if you can't hear it coming on for an extended period of time, the motor may need repair or replacement. The wires connecting to the fan may be the problem, preventing the fan from receiving electricity.

Several other problems could be keeping your freezer from freezing:

There could be leaks in one or several of the hoses in the refrigerator, which results in the cold air being lost instead of circulating properly throughout the fridge and freezer.

If you have the freezer so full that the cold air can't circulate, your food will thaw even though the freezer isn't malfunctioning. Always leave some space open in the freezer and try to not store food right up against the cooling vents.

The thermostat might have shorted out, which means the freezer can't accurately determine how cold it is. If this is the case, the refrigerator would probably not be working, either.

If your defrost drain becomes clogged, the water in the line will just refreeze over and over again, which could damage the lines as well as the fan. Always check the drain and make sure no sludge is building up in it if you have a self-defrosting refrigerator.

Always try to keep the freezer door closed for long periods of time. The more the door is opened, the more warm air is let in and cold air is released. If the door is opened frequently, the freezer could be warming faster than the fridge can cool it, which will thaw your food.

I hope this helps........

Good luck.

Hi,

As the weather is getting warmer for many people their freezer and/or refrigerator do not work right because of a dirty condenser coil...there are also many other things that can go wrong. If you are hearing a clicking or buzzing then check out the last two tips.

If your refrigerator is running but warm, then…

Check out this tip that I wrote about that... it is a great place to start trouble shooting your unit...and something that you can do rather then calling a repair person to do a simple thing for you...

Sounds like a defrost problem. Remove food from freezer section, take the back wall out after removing shelves, and use a hair blower to melt off the ice and frost. Most likely you need to replace the defrost heater.

Most/many times this is a clogged up or restricted defrost drain system, but once in a while the drain system has been cleaned and everything appears to be good but you still get ice in the defrost drip tray and such and the drain freezes over. Some manufacture designed kits to help and some home made remedies. http://www.applianceaid.com/defrost_drain_freezes.html
