If a temperature sensor is defective during installation, the controller does not work properly
and the sensor needs to be replaced. If the sensor is defective after some time of operation, the

times of the cooling cycles. In this way, the temperature in the freezer remains. Of course this
situation needs to be repaired as soon as possible.
