Hi iam working on a pury p200 ymfc mitsubishi city multi system. The system was idle for the last 6 odd years, was brought in to install new compressor and outdoor boards ( water damage , due to cover off outdoor unit , I installed new gas to system. System not working . I replaced the 4- way valve and i also Found one lower check valves stuck replaced all check valves. System now heats but still not cooling after replacing all these parts. I reset all the l.e, v s on the indoors also. Currently i have l.e.v 1and 3 motor heads replaced, and some of the indoor l.e.v heads replaced.
Unscrewed l.e.v 3 and can here gas passing. but indoors doing nothing.
Replaced old corroded solenoid head, very corroded not sure if body is opening properly to allow refrigerant to flow through l.e.v 3. Also tested all solenoid a and b heads.
Seems like refrigerant not leaving b.c box as suction pipes on each port not cold, solenoid block a/b/c andsuction pipe from condenser Icing up. Any help would be great,
Thanks.
