Hi everyone

Got an engineer coming to look at my multisplit tmrw.

One of the coils is staying cold when it is turned off so some refrigerant must be getting through to the coil that is off.

If I turn one of the other units off and leave the faulty one on the problem does not follow the unit so it must be something to do with the EEV on my bedroom unit.

The coil gets to the same temperature as the units that are calling for cooling.

I feel in winter this is going to cause heating problems as refrigerant will go to a coil that doesnt is turned off thus affecting other units that do require heating.

What should the engineer be checking tmrw and how long can I expect him to take to diagnose the problem, as I say its only one of the units doing this.

He has suggested that the valve motor may be shot or something blocking the valve from shutting.

Any help greatfully received.

Thanks.
