Why is my Spheros CC 355 Air Conditioner not cooling but the compressor is still running?

If your Spheros Air Conditioner isn't cooling while the compressor remains on, it could be due to several reasons. You might have a refrigerant leak, requiring a check for leakage and a refill to the correct amount. Another cause could be air or other gas in the system, which can be resolved by drawing a vacuum (min. 3h below 10mbar), replacing the filter dryer, and refilling to the correct amount. A dirty or defective expansion valve may also be the culprit, necessitating its replacement. Additionally, a dirty evaporator coil or air filter could be the cause, suggesting you clean the coil or clean/replace the filter.
