How to Fix / Troubleshooting
Safety first: Refrigerant is under pressure and must be handled by certified technicians.
- Step 1 – Visual check: Look for oil stains on coils and piping, which often accompany refrigerant leaks.
- Step 2 – Listen for hissing: With the unit off, listen near joints for any hissing sounds indicating a leak.
- Step 3 – Do not attempt recharge: Do not use sealants or attempt to recharge the system yourself; this can damage the unit and is often illegal.
- Step 4 – Call a professional: A technician should locate the leak, repair it, evacuate the system, and recharge with the correct refrigerant and weight per Sencor specifications.
