Hi @shalomie
Have you tried placing a thermometer in the freezer to read what the temperature actually is, and comparing it to the display temp, just in case the temperature is fluctuating all over the place?
(Allow for a degree or two difference between the thermometer readings as no two thermometers are exactly the same)
It is quite normal for the freezer temp to reach 32 degrees F at least once every 8-12 hours. (depends on manufacturer)
This is part of the auto defrost cycle, where the compressor and the evaporator fan are turned off and the temperature in the freezer is allowed to rise to 32-33 deg.F so that any frost in the freezer melts and drains away. The process is sped up by turning on the defrost heater in the freezer. It usually takes about 20-30 minutes.
After the defrost cycle time has elapsed (set by control board defrost timer)the compressor and the evaporator fan are switched back on and the freezer temp is driven back down to the required temperature. This takes time to achieve of course.
In normal operating mode (not defrost cycle mode) the temperature in the freezer can vary slightly around the 0 deg. mark because cold air “falls” out of the freezer being replaced by warmer air, when the door is opened during normal use.
