Fridge freezer refrigerator ice makers

Usually found on high end units, it freezes ice cubes ready for appliance owners when needed. it will be located in the freezer unit to take advantage of the freezing temperatures.

These units need to be connected to the cold water mains connection in order for the ice to be renewed. 

The temps in the ice make are monitors by an NTC sensor  and when the ice is required a motor with turn the tray to free the ice up ready for dropping into the glass required. An arm on the front of the ice maker makes sure that the ice does not overfill .

These unit usually have a test button on them so they can be tested when needed, its a common failure to see the tray snap from the maker this would water to spill over the food in the unit so is usually spotted quite quickly.

You could get a motor failure or a failure in the control side of the system so test for power at the motor prior to replacing and ohm test the motor to see if it is faulty as well. If the arm that stops the ice maker broke it could continuously make ice even when not needed this can be a costly fault so keep an eye out for damage.


Test motor for ohms resistance reading 40 ohms for smaller motors , Test the micro switches , Test any fans for ohms and then test the NTC for ohms reading , ensure no shorts in the parts and look after service information on your model to check ohms readings.



Fridge freezer ice buckets

Ice from the ice maker is dropped into the these ice buckets and it then can be used to dispense the ice cubes to the appliance user. To dispense the ice a motor and large screw auger is used the motor turns the auger and the auger pulls the ice towards the exit. other than the screw failing or coming lose the only other problems could be freezing up or the motor failing. Sometimes there may be a solenoid fitted this is a switch to prevent crushing of the ice so either full cubes or crushed ice can be selected by user.

To test the motor take an ohms reading and match this to service specs for appliance make sure there are no shorts or earth leakage currents by testing for continuity.

Same thing for the solenoid if one is fitted 

The plastic bucket can weaken and crack over time if so replace it.
