  If your Phcbi Freezer isn't operating when plugged in, several factors could be at play. First, check the power supply connection to ensure it's properly connected. Verify that the power supply's capacity and voltage are sufficient. Also, check for any power supply issues or power failures in your location. The circuit breaker on the supply circuit might be activated, so try resetting it. Lastly, inspect the fuse on the supply circuit; if it's blown, replace it.

  An alarm activation on your Phcbi Freezer can stem from several causes. First, check the power supply connection to ensure it's properly connected. Verify that the power supply's capacity and voltage are sufficient. Also, check for any power supply issues or power failures in your location. The circuit breaker on the supply circuit might be activated, so try resetting it. Lastly, inspect the fuse on the supply circuit; if it's blown, replace it. Additionally, it could be due to a change in the chamber temperature setting, so adjust it as needed. The door may have been kept open for too long; make sure to close it. Avoid placing containers with high temperatures inside the chamber; allow them to cool first. Ensure the door is fully closed.
