How to Fix / Troubleshooting
Safety first: Do not attempt to add refrigerant yourself.
User checks:
- Look for oil stains: Inspect flare joints and coils for oily residue, which indicates leaks.
- Listen for hissing: In a quiet environment, listen near joints for hissing sounds.
Resolution: A licensed Bosch technician must locate and repair leaks, evacuate, and recharge the system to the specified amount. Continued operation with low refrigerant can damage the compressor.
