Possible Causes
Blocked condenser airflow, failed condenser fan, dirty condenser coil, high ambient temperature, high refrigerant charge, high pressure switch failure
How to Fix / Troubleshooting
Safety: Disconnect power. High-pressure components can be dangerous; do not bypass safety switches.
- Clean condenser coil: Remove dust and debris from the condenser. Ensure front and rear grills are not blocked.
- Check condenser fan operation: Confirm the fan runs whenever the compressor is on. Replace the fan motor if it is not operating.
- Verify ventilation: Ensure the unit has proper clearance and is not installed in a closed cabinet without ventilation.
- Inspect high pressure switch: Locate the high pressure switch on the discharge line. Check wiring and connectors for damage.
- Technician service: If E7 recurs after cleaning and fan repair, a refrigeration problem (overcharge, non-condensables, water-cooled condenser issues) may exist and must be corrected by a professional.
