Ice making mechanism prevents ice from falling properly
If the resistance value is above 27K, the controller is judged to be bad and should be replaced. If the resistance is lower than 27K, each of the two lines must be broken. The resistance will be adjusted from 27K to 28K by series connection of resistors.
Maintenance method: use multimeter to measure the resistance of water temperature probe (in water tank, when the water temperature is close to 0 degrees centigrade, remove the three core wire in the control box, test the resistance value of two lines on both sides)
Fault reason: measuring water temperature probe fault, making intelligent control system can not effectively perceive water temperature and work, misjudgment, program error, or controller failure.
