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.

How to fix a Spheros Air Conditioner when the compressor doesn't work?

  If the compressor of your Spheros Air Conditioner isn't working, the issue could stem from several causes. A defective fuse or relay might be the problem, in which case you should replace the fuse or relay. Alternatively, the magnetic clutch could be burned, requiring repair or replacement. A blocked compressor could also be the cause, suggesting you repair or replace the compressor. Finally, an open low pressure switch, possibly due to a lack of gas in the system or a defective switch, could be the reason.

What to do if Spheros CC 355 Air Conditioner has high discharge pressure?
- M
  Michelle GonzalezAug 16, 2025
  If your Spheros Air Conditioner is experiencing high discharge pressure, several factors could be responsible. There might be excess refrigerant in the system, requiring you to drain and capture refrigerant, then refill to the correct amount. Another possibility is an obstruction in the refrigerant flow, so check for restrictions such as a partially closed compressor valve, a blocked expansion valve, or a blocked filter dryer. A dirty condenser coil could also be the cause, so clean and wash it. If the condenser motor is stopped, refer to symptom 'Condenser motor is stopped'.

Why does my Spheros CC 355 have low suction pressure?
- M
  Mark PettyAug 25, 2025
  Low suction pressure in your Spheros Air Conditioner can arise from several issues. A lack of refrigerant could be the cause, so check for leakage and refill to the correct amount. If the air return temperature is too low, reposition the temperature sensor to a more appropriate location. A dirty or defective expansion valve might also be responsible, suggesting you clean or replace the valve. Other potential causes include a stopped evaporator motor (replace the motor), a restriction in the system (eliminate the restriction), a loaded air filter (clean or replace the filter), or a dirty evaporator coil (clean the coil).
