my self-defrosting (Fridgedair - upright and side by side)
fridge is freezing up on a weekly cycle. If i defrost the
**cooling coils** in the freezer manually on Monday the coils are
frozen/frosted up by the following Monday... essentially blocking
the cold air from going to the refridgerator side.

When i manually defrosted i measured the resistance of the heater
element going around the cooling coils at 19.2 Ohms ?

What could be possible conditions to cause such a problem ?

My guess would be a bad defrost timer. As I understand it, these are
typically little timing motor bits, not all that unlike dryer timers,
that operate a defrost cycle every now and again, shutting off the
compressor and turning on the defrost elements for a spell.

what sort of components or actions should i be doing to repair ?

If it's the timer, replacing it would be the obvious correct repair (and
stands a good chance of being economical, to boot). Of course, if it's
an old fridge, you may be money ahead in the long term to get a new,
more efficient model instead, simply based upon electricity savings.
