1996 Amana SXD22S2 Refrigerator has soft ice cream and seems to be
running a lot, so the usual drill:
1) Vacuum the coils under the front. No good: freezer still 15
degrees. More drastic measures required.
2) Pull it out and clean dust from fan exit grill (which is spinning
nicely), and do my best with a brush on a springy wire to clean dust
off of the nearly impossible to reach coils under the unit, still no
improvement. Hmm. Begin diagnostic phase.
3) Check fan inside the freezer is running (ok) and evaporator coils
(by the time I pulled the sheet metal) had no frost build-up (ok).
Running out of ideas.
4) Run defrost cycle by opening/closing the door 4 times within 8
seconds, verify heater comes on (ok). Unplug to stop the defrost
cycle (no frost to thaw).
5) Set the thermostat to max cool. Let it run an hour (it stays
running the whole time) and check temperature of evaporator coils with
non-contact instant IR thermometer. Inlet tube in the zero degree
range, outlet tube in the 25 degree range, but inlet and outlet are
both on the top. On the bottom (half-way through the path), the
temperature was 45 degrees! Temperature of coils under the toe kick
are 77 degrees, the room is 70 degrees.
So, I think I know the answer: new fridge, right? I know that
replacing a compressor is not a good idea, if that's the problem, but
any hope at all in adding refrigerant?
