1. 1

   Compare the read value from sensor TR5 with an external thermometer.

2. 2

   Connect a manometer to the refrigerant circuit and measure the low pressure. Compare the evaporating temperature value from JR0 with the measured value.

3. 3

   Use a magnet to manually change the position of the electronic expansion valve (EEV) during operation to check if it's stuck.
