If your Orbegozo ADR 93 air conditioner alternates between cold air and hot air, here are the most common causes and how to fix them:
Main Causes
- Dirty or clogged filter - This is the most frequent cause. A dirty filter reduces airflow and cooling efficiency. Clean or replace the filter according to the recommendations in the manual.
- Blocked or poorly connected exhaust hose - If the hot air exhaust hose is bent, blocked, or disconnected, the unit cannot properly expel heat and produces lukewarm air. Check that the hose is properly connected and straight.
- Open doors or windows - The air conditioner needs a closed room to maintain cooling. Ingress of hot air significantly reduces efficiency and can cause the temperature to stagnate.
- Incorrect operating mode - Make sure you are in cooling mode. Ventilation or dehumidification modes do not produce cold air.
- Normal thermostat cycles - Some portable air conditioners are designed for automatic on/off cycles. If the room is already cooled, the unit may switch to simple air circulation, which may feel lukewarm. This is normal behavior.
Troubleshooting Steps
- Clean the unit's filter
- Check that the exhaust hose is straight, properly connected, and unobstructed
- Close all doors and windows
- Lower the temperature setting
- Confirm that you are in cooling mode
- Wait a few minutes - the compressor may need to restart
If the problem persists after these checks, the compressor or cooling system may require technical intervention.
