Question about Refrigerators
After coming back home from a week long holidays the fridge was in error mode. All the food was rotten and took a while to clean the mess. Had fault 27 PM Comm error. Checked the connection between the touch panel and the mother board. Unit started work as normal after cycling power. Temperature reaches the set point but not as it supposed to be. there is not enough circulation to freeze or cool. Suspect the fans. These fans have 3 wires and one being the feed back pulse to tell the mother board that the fan is turning. Please send me your ideas before ripping every thing apart to access the fans in the main fridge and the freezer. It seems that the 2 bottom compartments are working fine.

Art, I need to get a little more information from you. Does the condenser fan under the refrigerator seem to work and blowing warm air from below and or behind the refrigerator? The motor feeling warm is OK. Only when too hot to touch on top. Needs to cycle also. When you opened the freezer did you hear the fan blowing? Thanks, JT

The fridge gets its cold air from the freezer through a vent
between the freezer and fridge.The fan in the freezer blows air through
it. There is a flap you adjust with the
fridge temp. control. Make sure it's opening and closing when you adjust the
fridge temp ..

The mos common reasons for freezer ice build up are"
Poor cooling is often the result of a heavy frost build-up on the evaporator coils. You can't see these coils without removing a panel on the inside of your freezer. A sure sign that there is a build-up is the presence of any frost or ice build-up on the inside walls, floor, or ceiling of the freezer. Such a frost build-up usually indicates a problem in the self-defrosting system or damaged door gaskets.
The refrigerator is supposed to self-defrost approximately four times in every 24 hour period. If one of the components in the self-defrosting system fails, the refrigerator continues to try to cool. Eventually, though, so much frost builds up on the evaporator coils that the circulating fan can't draw air over the coils. There may still be a small amount of cooling because the coils are icy, but with no air flow over the coils, cooling in the refrigerator compartment is quite limited.
Here's an inexpensive, though inconvenient, way to determine if the problem is with the self-defrosting system. Remove all of the perishable food from the refrigerator and freezer, turn the thermostat in the refrigerator to Off, and leave the doors open for 24 to 48 hours. (Be sure to have several towels ready in case the melting frost and ice causes the drip pan to overflow). This allows the refrigerator to defrost "manually." When the frost and ice build-up has completely melted away, turn the thermostat back to a normal setting. If the refrigerator then cools properly, it indicates a problem with one of three components in the self-defrosting system:
The defrost timer
The defrost thermostat (also called the bi-metal switch)
The defrost heater
If it still does not cool properly, there may be a problem with the refrigerant level or the compressor. You may need to consult with a qualified appliance repair technician to further diagnose the problem

When the freezer section gets cold and reaches
its required cooling temperature, after that the frost on freezer section
starts defrosting and the cooling fan in the freezer section blows this cool
air from freezer to fridge. But if the defrost cycle does not start then over ice will get collected on freezer ventilations and that will block the air passing section from freezer to fridge, so the
freezer gets cool but fridge section does not cool.Try manual defrost by unplugging the
refrigerator from main power outlet for 4 hours then reconnect it and check, if
the same problem is noticed again,. If yes then its defrost board problem. The
defrost board located in the back of fridge section. You can get required parts
from www.repairclinic.com or from online sears part site. ------------- Thank
