  If your Phcbi Freezer isn't getting cold enough, several factors could be at play. Start by ensuring you're not placing warm materials inside and limit how often you open the door. Check that the chamber temperature is set correctly (not lower than -86 oC), and that the unit isn't in direct sunlight or near heat sources. Make sure ventilation around the unit isn't blocked and reduce the number of stored items. Ensure the access port is covered when not in use and that the door gaskets are clean and undamaged. If the door seal is damaged, contact our sales representative or agent for replacement.

  If the alarm activates during operation of your Phcbi Freezer, it could be due to several reasons. First, check if the chamber temperature setting has been changed and adjust it if necessary. Also, ensure that the door hasn't been left open for an extended period. Avoid placing containers with high temperatures inside the chamber. If the LCD touch panel is unresponsive, try turning the power off and then on again.

  If the compressor in your Phcbi Freezer doesn't operate when you turn on the power switch (and the LCD touch panel is on), the capacity of the power supply might not be sufficient to start the compressor. Ensure that the power supply has enough capacity.
