Sub-Zero & Wolf Error Code EC 85
Overpressure on compressor
Common Causes
- 1Blocked condenser
- 2Refrigerant overcharge
- 3Condenser fan failure
Overpressure conditions can cause compressor housing failure. If EC 85 recurs after condenser cleaning, do not operate — call for professional service immediately.
Step-by-Step Troubleshooting
- 1
Immediately clean the condenser coils — a severely clogged condenser is the most common cause of overpressure
- 2
Verify the condenser fan is running and moving air across the condenser coil
- 3
Check for restricted airflow around the unit — built-in installations require proper ventilation clearances
- 4
If condenser is clean and fan works, suspect refrigerant overcharge from a previous service — requires gauge measurement
Pro Diagnostic Tip
Touch the discharge line leaving the compressor — it should be hot but not too hot to touch briefly. Scalding heat indicates overpressure. Sub-Zero high-pressure cutoff triggers at approximately 300 PSI.
