Viking freezer and fridge power on but not getting cold.

I am curious how you know it is on unless you get inside. Some have magnet switches that will not cycle until the gasket seals.

Sounds short of refrigerant or very blocked up condenser. Is there a lot of heat from the back/ underneath>

Is the freezer itself getting cold.To blow cold air.the freezer should get cold/friezed.the cold air blows from freezer to fridge side.first the freezer side gets cold, then when the freezer side gets enough cool to its set cooling temperature, at that time the defrost cycle starts.In defrost cycle the fan in the freezer starts running and the cool air from freezer starts going to fridge side.There is a ventilation passage between fridge and freezer from where this cool air passes.---------------- If in your case, the freezer is getting proper cold, but its not blowing cold air from freezer to fridge, then possibility is that, there is a blockage in ventilations.But if ventilation its clear, then its defrost problem.First try manual defrost reset procedure. The 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. It will take near to 4 hours to get run in its proper cooling cycle. Then check, if the problem returns again. Then its defrost board problem. ------------------------- BUT if in your case, the freezer section itself is not getting cold, then the problem is compressor related.The compressor is the part which cools the freezer frost.In the compressor, there is a refrigerant to cool the freezer.If the compressor gets weak or the refrigerant gets low, then it will not cool the freezer, if the freezer is not cool then it will blow warm air from freezer to fridge, in defrost cycle.In that case, the compressor is faulty and its the cause of problem.------------ So you will have to first check , that is your freezer getting cold or not.as per that you can start the troubleshooting.------------------

You can get required parts from from online sites like: --- www.repairclinic.com or from searspartsdirect online site. --------- This should help.Thanks.Helpmech.

remove the rear cover inside the freezer if it has a lot of frost on it,then the evaporator coil is frozen up and you cant blow cold air over or thru a solid block of ice,defrost it,then check the defrost heating element,defrost thermostat and timer or defrost circuitry for no power or defective components,you can use a hand held hair dryer to defrost it quicker

In case the freezer not getting cold. maybe the tube is leaking .the freon gas scape. or your compessor is defective

more than likely the defroster inside the freezer has gone bad. This defroster is located in the space between the fridge and freezer and activates to defrost the freezer and stop build up of ice in the freezer.. If it is bad the freezer will not keep the fridge nor freezer cold.

It has seperate cooling circuits as you describe the problem can be a leak of refrigerant in the freezer circuit.if there is no heating up in the freezer condensing coil.It has to be check for the leakage.

I suspect you may have a faulty compressor! Do you notice if the compressor starts?

The most common problem with refrigerators not cooling when the freezer cooling is the fan which supplies cold air to the freezer. Not easy to get to in most cases. Another problem is the vent to the fridge part is blocked or not operating with the adjustment control.

It should work the same as before. Does the compressor get really hot after running a while? If so it could be low on charge, or there could be a restriction inside the refrigeration system. Either way a professional would have to look at it.
