Do you see snow on the panel that covers the evaporator?


No, not at all. In this fridge, the evaporator coil is located UNDER
the freezer floor. To remove that freezer floor, I have to remove both
the freezer compartment door and the fridge fresh food compartment
door.
I will do that with the fridge running so as to preserve the frost
pattern on the evaporator coil.



I defrosted the fridge manually by unplugging it, propping the fridge
and freezer doors open, directing the melt water tube into a large
shallow pan on the floor behind the fridge and letting any frost on the
evaporator melt.

I collected about a quart of water, which to me means that the
evaporator was pretty iced up.

Once I was convinced that the evaporator coils were fully defrosted, I
put a plastic cup of water (covered by a jar lid) in the freezer
compartment and plugged the fridge back in. This test will determine
whether the fridge works properly when the evaporator coils ARE NOT
frosted up. If that water still doesn't freeze, then I'll look at the
frost pattern on the evaporator to see if it indicates a low refrigerant
charge. If the water does freeze, then I'm convinced the problem is
excessive frost accumulation on the evaporator coils, and I'm gonna
blame the DTS for that cuz the defrost heater shows continuity.

If replacing the defrost termination switch still doesn't solve the
problem, and the evaporator is frosted up along it's full length so it's
not a weak refrigerant charge, then I'm willing to call in an appliance
service tech to figure out what's wrong. I figure that if I go this far
and still can't solve the problem, then I'm prepared to pay for a
service call. For 99% of appliance problems, going as far as I have
will have determined the cause of the problem and the solution. I'm
willing to pay for that remaining 1 percent that I can't solve myself.

On this fridge, I have to remove the fridge and freezer compartment
doors to remove the freezer compartment floor. The evaporator is under
the freezer compartment floor. I have to bend the hard plastic freezer
floor to get it out of the freezer compartment. So, I'll let the fridge
fully defrost a second time so that the plastic I'm bending won't break.
Then I'll remove the freezer floor and plug the fridge back in to see
how the frost forms on the evaporator.




Looking forward to the next exciting installment.
Sounds like you're closer to diagnosis.
