What does Traulsen CondenserClean Alarm mean?
The clean-condenser alarm tells the operator that the condenser is not rejecting heat properly, most often because the condenser coil is dirty or airflow is restricted. Keeping the condenser clean is routine maintenance; if ignored, restricted heat rejection raises head pressure and cabinet temperature and can shorten compressor life.
Symptoms
- Alarm LED illuminated and horn sounding on the control
- Visibly dirty condenser coil
- Reduced or blocked airflow at the top or rear of the unit
- Unit struggling to hold temperature in a warm room
Common causes
- Dirty condenser coil
- Disconnected or failed condenser fan
- Obstructions at the top or rear of the unit
- Room temperature too warm or airflow restricted by nearby objects

Diagnostic steps
Clean the condenser coil
Check whether the condenser coil is dirty and clean it if so.
Check the condenser fan
Confirm the condenser fan is connected; reconnect it, and replace the fan if it is failed.
Clear obstructions
Remove any obstructions at the top or rear of the unit that block airflow.
Address room conditions
If the room is too warm, lower the room temperature so the condenser can reject heat.
Improve airflow
Move the unit or nearby objects to restore unrestricted airflow around the condenser.
When to call a professional
Coil cleaning and clearing obstructions are routine maintenance the operator can perform with power off. Call a technician if the alarm continues after cleaning and clearing airflow, which points to a disconnected or failed condenser fan. Replacing the fan motor involves electrical connections and should be done by qualified service personnel to avoid shock and to confirm the component is truly defective.
