What to do if my Lauda Chiller shows an HP alarm due to a pressure switch?
- CchristiantateAug 8, 2025
If your Lauda Chiller displays an HP alarm related to the pressure switch, several factors could be the cause. First, ensure that the lateral panels of the housing are closed. Next, check for adequate airflow into the condenser, ensuring there is enough free space and cleaning the condenser if it's dirty. If the ambient temperature is too high, wait for it to decrease. Should the motor fan not be working (not turning when the chiller is running), or if you suspect a high-pressure switch failure, contact authorized technical service.
