Need some urgent help, Please.

Temperature in our cold storage suddenly becomes warm. Compressor is running but I noticed that there are ice building up on the filter drier and the TXV. Is it an indication of clogged filter, co'z the unit was running perfectly before. Also I noticed that the compressor has very little oil. What is the suitable oil for my compressor. It was from Carrier and the refrigerant is 134A.

Thanks!!!

You are right, drier is blocked, refrigerant flows slower, oil doe's not return.
Replace the drier and see how the temp drop.

If you have enough oil to run the compressor, don't fill with new oil the installation. It will go back to the oil separator / compressor once you have changed the filter and started again the installation.
