Mitsubishi electric suction pipe freezing

[Craig Johnston]

I could some kind person help me please, I have a Mitsubishi puhz-rp125yha2.
The suction pipe is frozen all the way into the compressor. I have check filters, fan motors and coils. All ok. Is this liquid coming back to the compressor or possible charge issue?

Thanks

Check the expansion valve isn't fully opened

How do you check that with the lev? Thanks

[Craig Johnston]

No errors. Unit is working ok

is this the pipework within the condenser or the suction line from evap to condenser- is the lagging 13mm wall? you can get away with 9mm but if lagging is compressed with cableties or squashed on cable tray then that can cause sweating/frosting on suction line?- run it in test mode and view coil temp should be above freezing- otherwise ****ted up coil?

Are the indoor filters clean?
