We have a Frigidaire 16 cubic foot frost-free upright freezer. Most of the
time it will maintain a -10°F. temperature. Periodically, perhaps every 6
months or so, the temperature rises to between 10-20° above 0°F. If I remove
the contents and allow the freezer to stand empty with the door open for 24
hours, when I power it up again, it will return to the -10°F. temperature and
maintain that again for at least 6 months.
Any ideas on what may be cause this?

Frost-free means that it periodically heats up enough to thaw any ice off
of the cooling coils. Are you sure that you are not just sometimes
observing it during its self defrost cycle? Although, it could be that
the thermostat is getting frosted up or something if it is for a prolonged
period of time.

I wish that was the problem. It's not the frost-free feature causing this.
I've checked the temperature regularly and it never goes lower than 10
degrees above zero when it's having this problem.
Perhaps the thermostat is the culprit.

The most likely cause is that you didn't shut the door properly the
day before the problem. Probably a plastic sack of frozen food was
sticking over the gasket or you crammed too much in and the door
didn't close all the way and that failure on your part let in heat and
moisture. That iced up your coils much more than your defrost cycle
could handle so from then on your coils never defrost. Eventually
there is complete obstruction by the ice.
Learn to clear your gasket area when you shut the fridge and all will

I don't think this is the problem. I'm obsessive about making sure the
door is closed completely. In fact, when the door is first closed it's
almost as though the box is pulling a vacuum, as the door cannot be opened
at all for a few seconds.
I suppose it's possible that the coils are iced up, though I'm not sure
what caused it. That would seem logical, though, since giving the whole
unit a chance to stand open for 24 hours seems to correct the problem.
This has happened several times and always at about the 6th month mark.

This is almost definitely a frost/icing problem. You just need to figure out
why it is frosting excessively or not defrosting properly. Could even be a
clogged drain for the defrost water if it has one. Could be a leaky gasket
allowing excess moisture inside but not likely since you say it seems to
vacuum seal when closed. Could be an improper defrost cycle due to bad
timer, heater or defrost thermostats. See if you can find out how it is
supposed to defrost. Could also be due to inadequate airflow caused by
partial blockage or sticking fan bearings.

I keep two thermometers in my fridge. One on the freezer side and
one on the milk side. A rubber band holds the thermometer to the
jar of olives so it is upright and easy to read, every time I open the
About twice a year, I open the door and find the temp reading 48
degrees or so. I immediatetly drag a large box or ice chest into the
kitchen and dump the freezer contents into the box. Then remove the
shelves (6 screws). Then remove the back panel over the hidden coil
(6 screws). I grab the hair dryer and put it on high and start
melting the ice over the coils. About 25 minutes later the last of
the ice fall to bottom of the freezer and I put it all back together
and go another 6 months before someone crams too much stuff into the
freezer making the door fail to shut properly.

All good points, Jim. Thanks! This is a freezer only, and I don't think
it's a door problem, but the result is the same. I'll be thawing it out in a
day or so and it should be fine for another 6 months. I just wish I could
eliminate the problem.
