  Poor cooling in your Phcbi Laboratory Equipment can occur due to several reasons: a large amount of items stored at once, a high ambient temperature, the outer door not being firmly closed, excessive frost buildup on the chamber wall, a blocked air intake vent, an improperly set temperature, direct sunlight exposure, a nearby heating source, or incorrectly set rubber cap and insulation for the access port.
