Is your refrigerator acting strange and you don't know why? Cold food compartment warm? Leaking water? Maybe I can help.
I just fixed mine for about $30 for two parts, and no repair call. I thought I'd share some of what I learned. I don't consider myself all that handy so this is written from a novice point of view - if this is you, don't be afraid!
Note: If your refrigerator is one of those newer models with a computer board, you'll likely have to call someone and replace the board. The same seems to be true for all those newer washers, dryers, etc. that are all computerized - they don't make many parts that can be fixed individually by the average person.
Ok, so I have a typical self-defrost model with the freezer on top. If yours is like this, you'll likely have a fan, defrost heater, and condenser behind the back wall of your freezer. (Some models, typically older ones, have the "guts" under the freezer floor.) The cold is produced here and circulated throughout the fridge compartment.
When the refrigerator goes into defrost cycle (typically for 6-20 min. every 6-8 hrs. depending on the model), the heater heats the coils and melts the ice. There is a hole in the tray underneath the coils where the water goes down into a hose and down to an evaporator tray. Often, this hole gets clogged with ice which gets worse with time over repeated cycles of melting and cooling. Then the water has nowhere to go and ice will build up on the coils, and/or water will leak from inside the refrigerator and you will see puddles on the floor, or the air cannot circulate well enough to cool the refrigerator.
Now that you have a basic understanding of how it works, why not take it apart and see if you can find the problem? If you can put the food in another refrigerator or a cooler you might be able to save it.
