Mitsubishi electric suction pipe freezing
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

Re: Mitsubishi electric suction pipe freezing
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?
