- Dirty or obstructed air vents.
- Faulty temperature probe.
Diagnosis Steps:
- Examine the air vents for any obstructions.
- Check the functionality of the temperature probe using calibration tools.
Solutions:
- Clean air vents and ensure proper airflow.
- Replace the temperature probe if it is faulty.
Symptom-Cause-Solution Matrix
| Symptom | Probable Cause | Solution |
|---|---|---|
| Equipment Does Not Power On | Power cord issue, circuit breaker tripped | Secure connections, replace cord |
| Error Code E-03 | Sensor malfunction | Reconnect or replace sensor |
| Inconsistent Temperature Readings | Dirty vents, faulty probe | Clean vents, replace probe |
