Possible Causes
Room temperature below operating range, Faulty low‑temperature sensor reading, Defrost sensor mis‑positioned, Main PCB misinterpreting sensor data
How to Fix / Troubleshooting
Safety: Turn off and unplug the unit before moving it.
Steps:
- Check room temperature: Verify the room is within the Meaco specified range (typically above 5 °C). If the room is too cold, relocate the unit to a warmer area.
- Allow warm‑up: If the unit was stored in a cold environment, let it sit unplugged at room temperature for several hours before use.
- Sensor inspection: If the room is warm but E9 persists, inspect the evaporator/defrost NTC sensor for correct placement and secure contact with the coil.
- Replace sensor: If the sensor reads incorrect values (tested with a multimeter) or is damaged, replace it with a genuine Meaco sensor.
- PCB issue: Persistent E9 with a known‑good sensor may indicate a faulty main control PCB, requiring professional replacement.
