De-Icing problem on PANASONIC E12BKP
PANASONIC E12BKP
Problems with de-icing on the outdoor-unit.
The inner section is cleaned, and new fan-motor with new type of bearing set in.
FaultCode F11 is active. I.e. errors on 4-way valve or V-coil.
The problem is that the outdoor-unit cant manage the de-icing on the outdoor-unit, when the 4-way valve is turned.
The fan on the outdoor-unit do not stop to rotate under the de-icing process. I`am not sure if the fan should come to completle stop when de-icing happens, and, if it is here the problem is located?
Have tried to de-ice with hot water. After start-up the heat exchanger was effective, and gave much heat from the inner-unit. The ice also smoothly came over the all area on the outdoor-unit exchanger.
After a period in full operation the unit went to de-icing mode, and in connection with this – the problem start. The outdoor-unit do not carry out the effective de-icing.
I can under the de-icing process see of power-consumption, that the compressor works itself up, and consumption is located at approximately 550 W - 600 W.
What can be the problem with bad de-icing?
