Cooling issue We had a power outage and now our fridge and freezer will not cool, the fan is turning on and I have looked at the computer board and see no damage or burnt contacts or wires and I see nothing worng with the the underside of the appliance. What is the first solution to solving this problem? The black thing that I assume holds freon is cool to the touch. Help..... Shanna

check capacitor to compressor if ok possible bad compressor if no voltage to compressor bad board

how long was the power out...

Depending how long the power was off you may have an ice blockage in the freezer. Normal cooling causes the freezer coils to build up frost and snow coating all over the coils. A normal defrost cycle melts that frost/snow off and keeps the coils clear so the fans can move air through the coils.During the power outage the frost may have started to melt wetting the snow. If the refrigerator then came on and re-froze the wet frost/snow into a solid block of ice, the normal defrost cycle would not be able to clear that solid ice out. So it may be blocking the air flow. Remove freezer back panel and see if there is ice back there. If yes--use something like a hair dryer to melt everything out until it is completely clear. Make sure the fans are running also.

have a fridge technician as the power surge from the outage may have damaged the power board.

If the fan in the freezer stops, then coll air from freezer will not pass from freezer section to fridge section.In that case, the freezer section will get over frosted but fridge section will not get cold, because cool air will not pass from freezer to fridge.The fan is there for two things, 1) for cooling the heating evaporator coil and 2) For flowing the cool air from freezer to fridge.---------- If the frost is getting collected and fan is getting stuck up in frost, then this is the problem.The defrost cycle is not running, the cooling cycle is running.---------------
This problem is called defrost problem.-------------

So first thing you try is , perform, manual defrost reset procedure.---------

The manual defrost reset procedure is as follows : ----
First unplug the unit from main power outlet. Then empty whole unit completely. Then keep both the doors open. Wait for 24 hours. All the ice collected on the coils and in the freezer section will get melted. Clean the water from the sections. Then Connect the power cord of the unit to main power outlet after 24 hours/.Then set the temperature to normal in both fridge and freezer section. Then check,if same frost is getting collected, then its defrost problem,. If it's again building up ice that means the unit is not defrosting. It's starting the cooling procedure, and then while defrosting, it's not working. The defrost assembly consists of three main parts. The defrost thermostat, the defrost heater and defrost board. Any of the one is not functioning. When thermostat sense the maximum cooling, it triggers the defrost heater to start heating and this defrosts the ice collected on the coils and the system works. Both thermostat and heater are controlled by defrost board. First the thermostat and defrost heater to be checked, if both check ok by meter and visually, then its defrost board causing the problem. You can get required parts from from online sites like: --- www.repairclinic.com or from searspartsdirect online site. --------- This should help.Thanks.Helpmech.

Sounds like there is a low Freon issue in the unit.

Possible faulty freezer fan motor. Dirty condenser. Faulty control board.

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.Its defrost problem. Try manual defrost by unplugging the refrigerator from main power outlet for 24 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 you.

the problem is going to more then likely in the main control board which is on the back of the refrigerator in a little compartment this board is bad about going out if you have power surges or outages

where to look for the defrost timer on the LG top freezer modle
