Why is my Phcbi Refrigerator not cold enough?

  James HillAug 6, 2025
  If your Phcbi Refrigerator chamber isn't getting cold enough, several factors could be at play. The outer door may be opened frequently, or the inner door might be ajar. Direct sunlight, blocked ventilation, or a nearby heat source can also affect cooling. Ensure the ambient temperature is within 5 oC and 35 oC. Overloading the refrigerator or blocking the air exhaust vent with items can impede cooling. Also, make sure the access port is covered with insulation and rubber caps when not in use. Damaged door gaskets or foreign substances between them can also cause this issue; if the gasket is damaged, contact a sales representative or agent for replacement.

  If the alarm on your Phcbi Refrigerator is activated during operation, it could be due to several reasons: the unit might not be properly connected to the power supply, or the power supply's capacity and voltage might be insufficient. There could be a power failure, or the circuit breaker on the supply circuit might be activated (a 15 A or more breaker is recommended). The fuse on the supply circuit could also be blown. Additionally, the outer door may have been left open for an extended period or is currently open. If an error code is displayed on the temperature display, contact a sales representative or agent.
