Question about Refrigerators
same thing happened to me with a westinghouse upside down fridge freezer yesterday. i talked to a mate of mine who is a refrigeration mechanic and he said to check the air flow going into the fridge via the freezer and to see if the fan above the evaporator was working. he also said you would probably have to have the fridge light switch depressed as the fan is designed to only run when the fridge door is closed. when i removed the cover in the back of the freezer to inspect the fan i found the fan was spinning okay, but my evaporator was choked up with ice. i gave it a good defrost and clean out and everything seems okay now. i think the heating element around the evaporator (frost free) is not working and that is why it has iced up. apparently it is very important to have good airflow in and around the evaporator so if it is iced up or you have too much stuff in your freezer it will not be efficient and your refrigerator performance will suffer.
to have a rough idea on whether you have enough gas in your system, he suggested feeling the pipes coming out of the compressor. in normal conditions one should be quite hot to touch and the other should be a little bit cooler than room temperature. your condensor (which is the big coil up the back of the fridge should be warm and your evaporator (coil behind a cover in your freezer should be cold to touch)
hope this helped
