Have doors been open for a long period of time?
Reason
If freezer or refrigerator compartment door is open for a long time,
motor will keep running to make lost cold air.
Also it will continue to run when the door is not fully closed.
When the temperature is stabilized, the motor will operate normally.
How to fix
Use after the door is closed.
Motor will stop running when the inner temperature meets the set temperature.
Temperature sensors
Compressor runs until a certain temperature is reached
