Hello Sounds like a restriction/clog if the unit is (pumping down) .try adding freon when the compressor cools off & starts again.See if the low side #s improve.Make sure the service valves are open.

I have a 2008 samsung mini split mho50fxca2a with a I trip pfc overcurrent error what is this and where to start? also shows e4 67 which is compressor rotation error?


Your 2 errors are most likely related to the compressor itself and the power supply feeding it. If the system is an inverter system, there is usually an "inverter board" or power control board that sends high voltage (usually in DC rectified voltage) to the compressor. If the board is not functioning correctly or if there is an issue with the compressor, it may cause a reverse rotation error along with the power error. Additionally, the compressor itself may have failed and may have shorted or welded windings. This condition can be especially dangerous due to the potential of electricity arcing and the possibility of refrigerant loss. If you are not a technician trained to work on the equipment, I would NOT advise attempting a repair. Some of the power supplies in those units can discharge over 300v DC and there are quite a few components that can cause serious injury. I would call a technician to diagnose the issue.

What does error code 461 means on a samsung ?rc140dhxga hide away unit


Hi Jaco,
to trouble shoot this problem,you need to make some eliminations:
1.Check the standing pressure of the refrigerant (gas).If it is low that could cause the compressor to over heat and eventually fail.
2.The compressor could be drawing more current from the inverter causing it to trip.
3.The inverter card could be faulty.Try to run the unit with a similar card from a similar unit before your consider buying a new card.
4.The start capacitor/run could be fault causing the compressor draining a lot of current from the inverter.Inspect the capacitor for visible electrolyte leakage or bulging casing.Try one from working unit.

WHAT IS AN error code 461


This is a fault to do with the power inverter for your compressor in the out door unit.This is caused by :
1.compressor failure or faulty
2.Inverter card faulty,tr to use another inverter card from a working unit before buying a new one
3.Check that refrigerant standing pressure is adquate
4.Check that the capacitors start/run are not leaking,check for electrolyte leakage.Try one from the working unit

It sounds like your inverter is at fault. You will need an inverter tester ( most good service techs will have one ) to prove that the output to the compressor is correct. If the inverter is okay then it will be the compressor at fault with a location error or it is simply seized. A common fault that caused this was the eev remained closed (coil failure ) and caused the compressor to over heat.

Hello have a inverter LG Airconditioner and it keeps turning itself off and showing the letters C6? Any ideas


Error Code: C6 Problem: Inverter compressor run current high

SOLUTIONS:
- check [resistance of] compressor windings all equal 1 to 4 ohms

- check [resistance] to earth 50 Mohm minimum

- check run current

I'd also check the motor capacitor(s)

Probably best to explain/print out and give to authorised serviceman
