Symptoms: the compressor has been working to cool, the pump has been working pumping, ice is getting thicker, but can not enter the dehydration program for ice falling.
Cause: Test the temperature probe, the intelligent control system can not effectively perceive the water temperature and work, error program error, or controller failure.
Maintenance: Use a multimeter to measure the resistance of the water temperature probe (when the water temperature in the tank is close to 0 째 C, unplug the three-wire in the control box and test the resistance of the two wires on both sides) , It is judged that the controller is bad, should be replaced, such as resistance is lower than 27K, you need to disconnect any of the two lines, through the way through the series resistance will be adjusted to 27K to 28K between
