I have A GE side by side refrige model GSH22KGMC WW that the defrost
cycle doesn't work . It frosts up after about every 2 weeks and I
manually defrost and all works great. I've looked for a defrost timer
and can't find one in the refrige.. I would like to know if the defrost
timer is part of the primary circuit board accessed from the back of
the refridge? Is the defrost heater and defrost thermostat accesed from
the panel at the rear of the freezer compartment? I assume it is
probably one of these parts and would like to know how to test which is
the problem.
Thanks for the help if someone can.

Might try something simple first like vacuuming out all the dust
bunnies from the machinery under the bottom of the fridge. If that
doesn't work, GE has a pretty good parts/service operation, and of
course there's always repairclinic.com and otrher similar sites. Good
luck.

I've looked for a defrost timer
and can't find one in the refrige..
CY: if it's a mechanical timer, it's probably in the box with the
control knobs.

I would like to know if the defrost
timer is part of the primary circuit board accessed from the
back of
the refridge?
CY: Some newer fridges have a board, others use a mechanical
timer.

Is the defrost heater and defrost thermostat accesed from
the panel at the rear of the freezer compartment?
CY: Yes, and the freezeer section is usually narrow. Makes for
some strange twisting and bending to get at it.

I assume it is
probably one of these parts and would like to know how to test
which is
the problem.
CY: You can wait till it's frozen. manually advance a mechanical
timer, and then check the current draw. Five amps is about right
for a defrost heater. If it's not drawing five amps, very often
the heater and termination thermostat are replaced together.

CY: Y'welcome.

Thanks to both of you for replying, it is a relatively new refrige and
I've checked everwhere for a mechanical timer, On the main circuit
board on the back one of the componts has defrost printed on the
circuit board next to a IC component that is about 3/4 x3/4 and I
suspect controls the timing. I did find the screen inside the back
compartment clogged with dust so I cleaned as suggested by Joe , so we
will see if that helps.
Thanks again both of you
