  If your Phcbi Freezer's chamber isn't cold enough, several factors could be the cause. First, remove any warm material that may have been placed inside. Minimize how often you open the door. Check if the chamber temperature setting is too high and lower it if necessary. Ensure the unit is not in direct sunlight and relocate it if it is. Confirm that there is adequate ventilation around the unit and move it away from any heat sources. Also, make sure the ambient temperature is within the recommended range. Reduce the number of items stored inside, and ensure the access port is covered with insulation and rubber caps when not in use. Remove any foreign substances between the door gaskets. If the door seal is damaged, contact your sales representative or agent for replacement.

  If your Phcbi Freezer isn't operating, even when plugged in, start by checking the power supply connection to ensure it's properly connected. Verify that the power supply's capacity and voltage meet the freezer's requirements. Check for a power failure in your location. Reset the circuit breaker if it has been activated, and replace the fuse if it's blown. Also, ensure the power supply plug is properly connected on the product side.

  The alarm on your Phcbi Freezer might activate due to several reasons. Check the power supply connection and ensure it's properly connected. Also, verify that the power supply's capacity and voltage are sufficient. A power failure could also trigger the alarm. Check if the circuit breaker has been activated and reset it if necessary, and replace the fuse if it's blown. Other causes include a changed chamber temperature setting (reset it, if needed), the door being left open for an extended period (close the door), or high-temperature containers placed inside (remove them). Ensure the door is fully closed.
