Defrost Timer: Which Part Number

Refrigerator & Freezer Repair
,
1

I got this Sub-Zero Looking Fridge from Habitat for Humanity. Has worked pretty good for 2 years.

A couple of times the fridge side gets warm.
I opened it up and saw the damper (#7914).
Just by looking at it I probably defrosted the whole unit.

Lately I have had all the symptoms.
Water in the Freezer floor.
Iced up roof.
Icemaker frooze solid - from dripping water above.

I wonder about the drain up there? Does this model have one? One forum suggested someone have it cleaned out…but said it was hard and I don’t see it in any exploded views.

The dial on the timer (part# 7405) is all beat up like
it has been dealt with before.

I have read and read and read many forums.

Basically I want to try a new timer.
Although I watch mine and it keeps moving.
Is it possible to still spin and not give a closure?
I hate to think it is intermittent. Can it, or should
it be a hard failure?

TWO different supplying companies have a #7405 timer.
One for 25, one for 45 dollars (quess which I want?)
the 25 is advertised as a 6 hour timer.
The other dosen’t say. They both have a different
…WRX09xxx Number listed for a Part Number 7405.

WHAT IF my existing timer is a replacement?
It says it is a 10 hour, non-ind, 60hz, 1/3 amp.

What might be better 6 hour or 10 hour?

Is there any real Brains or Boards in this older model?

Fridge side hold good at 25-38 degrees. Hard to get colder. The freezer (a 5 normal setting) I keep at 3 1/2 to 4 (warmer) cause it freezes great and I want to under work it of possible.

blah blah balh you ask?

What is the right timer part number? (WRX90 ???)
or based on defrost cycles, what to the Pros reccommend. 6hr or 9hr?

Total defrost has brought the unit back 3 times now.
I never realized the stress I feel knowing a whole fridges worth of food might (or is) spoiling !!!
Try finding block ice now days.

Thanks,
PATRICK

Thanks.
I saw that tube…Huge! Probably a 3/4" clear tube.

Last time I was up there on top and Vaccuming out the coils and the general area…I thought that was a wierd looking tube.

Now I know, and THANKS…
makes sense.

I WILL blow that sucker out first chance.
Blowing it Into the Left, Box side
(looking from the front).

So it drains from the compressor into the Box?
for evaporation of any condensated water?
I did notice residule and rust stains on the "slide out"
shelf the compressor sits on.
Must be from a past blockage.
I will clean that up to keep tabs on new blackages.

I guess as long as my timer is going round and round
it is OK. (6hr vs. 10hr) Must be a CAM set-up, and unless a cam breaks off, the opens and closures follow the rotation.

GENE- Thank You, sincerely

Is the evaporator fan in the freezer running.
If it is then it could be low on freon and can be recharged by a qualified tech.

My dryer isn’t drying but how do I tell if it is it the heating element, the thermostat or the fuse? Is there a way to know which part I need to replace.

[SIZE=2][FONT=Arial][SIZE=2]I just changed gearbox on my Kitchenaid washer and now it seems to agitate much harder then before? After replacing the gear box I filled the water to a light load and as it agitates it actually splashes some water out from the open lid??? The model number of the washer is KAWS700GQ0 and the gearbox part number used in the replacement is B0028081 item 423 it looks the same as the one I removed from the washer. is this normal or do I have another problem??[/SIZE]

The factory replacement part number for this model is 3360629. I would check to see if B0028081 subs to the number I gave you.
It is normal for water to splash out of the basket in small loads.

first of all the evaporator was freezing up into a solid block of ice,which of coarse caused everything to get nice and warm.so i replaced the defrost heater/thermostat assembly and two weeks later the same thing started.so i ordered the adaptive defrost control board,and just finished installing it.my question is how long should it take for the unit to self-defrost?it already has frost forming on the evaporator.i know,because if i push on the back of the freezer wall,i can hear it crunch.
