Kouwa Service & Repair Forum
The above Model is on a Machine where I continually get an \"E8\" Error for Thermal Relay Overload. The Compressor will run for no more than 1 minute. Amps or Watts run high. Seems like an internal failure on Compressor. Any other thoughts before I replace Compressor? Condenser Coil is clean, great airflow. Nothing noticeable at Liquid Filter screen before Cap Tube.Also on this Unit it says Refrigerant is R407C. Any ideas on how much Refrigerant is in System in pounds?Any Tech info on this unit in regards to the Refrigeration cycle would be great.Thank you,Andrew Maass
