I hope someone can help. I have an old Kenmore SxS refrigerator, model
number 106.8566782. It has been a reliable unit, and with normal
maintainence and regular cleaning, it has performed well over the last
20+ years. The other day, my wife called me at work to let me know
that the fridge was warm, and everything in the freezer had melted.
When I got home I inspected everything I could while cleaning the whole
thing out. I eventualy took off the control panel cover and bumped the
defrost timer with my finger and the compressor immediately kicked on.
Unfortunately, the next time the timer went to kick in the defrost
mode, the timer stalled again, and I advanced it to get it to run once
again. I looked up the part on Sears parts website and the
reccommended replacement for the original timer pn. 943435 part was pn.
482493. I located this timer locally and replaced it with the loose
lead for the motor on terminal 2 since the original timer was wired to
pins 2 and 3. The fridge seemed to work fine, and I could hear the
timer running, so I thought all was well. The next morning the unit
seemed fine, and everything was as cold as it should be. But a new
problem seems to have been created with the replacement of the timer.
When the fridge goes into the defrost cycle now, the items in the
freezer thaw out considerably. The bread and waffles are soft, there
is moisture on all the shelves and walls, and the ice in the icemaker
is clumping together. Once the defrost cycle is complete, the freezer
operates normally once again and everything freezes solid once again.
I did not experience this problem before the original timer failed, and
am wondering if something is wrong with the timer or the installation
of the timer. I have read that a defrost thermostat could cause this
problem, however, it seems odd to me that it would fail at the same
time as the timer did, when it hadn't exhibited a problem beforehand.
One thing of note is that when the thawing is occurring in the freezer,
during the defrost cycle presume, the evaporator fan is running and
warm air is coming from the vents inside the fridge and freezer. But,
when I looked at it a little while ago while it was thawing and the fan
was running, I cycled the defrost timer until the compressor turned on
then off again, and the fan turned off as well and everything is quiet.
Thanks in advance for any help with this. - Mike
