Re: Mitsubishi City Multi
There are several things that will prevent the compressor from ramping up to achieve target condensing temperature/pressure - one of these is the discharge temperature.
Have you checked this? This can be done by the dip switches on the outdoor PCB.
As I've posted above - also confirm the pressure transducers are reading the correct value. It could be that the system thinks that it's running at 28bar (for example) because the discharge transducer is readibg 6-7bar out.
If you come back with this answer then we can work through the problem with you.
This needs to be checked before worrying about clogged filters in the system.The difference between genius and stupidity is that genius has its limits.
