Hello
Had a weird problem with a PUHZP125VHA2 M/E split and was wondering if anyone has had a similar fault. Found the system not cooling properly. Checked the condenser and noticed the compressor kicks in after a couple minutes stops and after another couple minutes kicks in again and then stops after a similar time.
Contacted Mitsubishi tech who haven't encountered a problem like this especially as when it doesn't fault out on the controller even after 16 attempts.
Running pressures (r410a) suction between 160-180psi/liquid 180-280psi. Both condenser fan motors seen ok. Tested pump down, compressor windings ok. Unit at high level so unable to check inverter board so coming back with a scaffold. Spent a while on this and towards the end checked heating seems to be working. Found compressor pulling up to 12amps when stopping.
Any suggestions or thoughts would be appreciated hopefully going back to site this Tuesday.
Regards
