Refrigerator is not cooling at all.
When I pushed Freezer and Ice plus buttons simultaneously the error E and rU popped up.
What does this error means?

Hi Neel,

That error code isn't listed.

So its not cooling at all now? Are the fans in the freezer and refrigerator running? Pull the refrigerator out from the wall, then remove the lower access panel and see if the compressor and condenser fan, that sits next to the compressor, are running.

Its possibly the main PCB board that went out.

Here it is for your model:
EBR78940615 Pcb Assembly,main

Thank you for your response Mr. Jake.
Fans in freezer and refrigerator are working. Compressor and condenser fan are also working.
I pushed the reset button on main control board on back and now the error is gone. But still refrigerator and freezer is not cooling at all.

So the compressor is running and its still not cooling?

If that's the case, you have a sealed system problem. A sealed system problem is a refrigerant leak (not common), an inefficient compressor, or system restriction. Sealed system repairs are expensive and will often exceed the value of the machine.
