The frig is less than two years old. It is a side-by-side model. The
ice maker dispenses cubes into a container in the freezer door. There
is a photocell circuit that detects when the ice container in the door
is full. There is an ice maker on/off switch panel in the freezer
compartment that also contains the photodetector emitter.
The ice maker stopped working. I have been trying to diagnose the
problem. Water inlet valve is fine. The ice maker itself seems to
cycle fine and make cubes - when there is voltage to the ice maker from
The trouble is that sometimes the 115V line to the ice maker has
voltage on it, and mostly it doesn't. I cannot for the life of me
understand what the trouble is.
When I put a voltmeter on the input wires to the ice maker, there is
normally no voltage present. What can interrupt the supply voltage?
There is the ice maker on/off switch in the freezer compartment. If I
switch this back and forth it seems to make no difference - no voltage
to the ice maker. I removed the switch panel from the side of the
freezer compartment to see what it looks like, and there is a small
circuit board attached to the back of the switch panel, and a four wire
connector. The circuit board undoubtedly processes signals from the
ice bin full emitter and detector, as well as the setting of the on/off
switch. I have no idea how to diagnose this circuit board.
Can somebody help me out? I am thinking that there must be some sort
of repair manual that exists someplace, or some type of diagnostic help
on the internet, but all I can find is diagnostics for the ice maker
I am stuck.
