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.
