GE Monogram Freezing Vegetables

Refrigerator & Freezer Repair

My GE Monogram is freezing everything in the drawers. I had this problem several years ago and it was the door that lets the cold air come in from the freezer. That is working fine now.

I have replaced the main control board and the 2 temperature sensors in the refrigerator section, but it is still too cold. It doesn’t seem to matter what temperature I put the refrigerator on.

What could possibly be wrong with this thing?

i’m having the same problem with my fridge changed the main board and the two sensors and still the same problem. Did you find a solution to yours.

4

I haven’t come up with a solution yet. I am going to order 2 more sensors and change the ones out in the freezer.

I am having the exact problem you are with my GE Monogram side by side…did you ever find out the problem?

You might have a defrost problem, or a refrigeration problem. Measure the freezer temperature and post.

Well yesterday changed the sensor in the back of the vegetable drawer and today the refrigerator was still too cold. I think i’m going to change like you the sensors in the freezer side. So far have changed three sensors and the mainboard and still the same problem…:frowning: :mad:

Measuer freezer temperature and post.

Richappy - if you are still monitoring, I am having similar problems with a ge monogram zisb48dyb - installed ~14 years ago. A few years back I added the icing kit (http://www.appliancepartspros.com/ge-icing-kit-wr49x10021-ap2636547.html) and that cleared up most of my issues. I keep the condenser coils clean periodically with a vacuum brush.

Now, fresh food is freezing (e.g. ice crystals in milk, frozen yogurt containers, iced veggies), plus lots of moisture on the inside walls.

Temperature Readings (deg F, taken with an infrared thermo, about 6 inches from surface):

Left side - Freezer (outside wall / inside wall) - 6" in from door frame
3 / 8.5
5 / 5
3 / 3

Right side - Fresh Food (inside wall / outside wall) - 6" in from door frame
48 / 39
28 / 30
33 / 30

Note - at the bottom/left/rear of the fresh food compartment, there is a plastic "radiator" looking thing filled with fluid. That liquid is frozen solid.

So - all told, it is not cooling sufficiently in freezer, and too cold in fresh food side with too much variation.

Thoughts? Where should I start?
I will turn off and defrost over the weekend - while its turned off I would like to troubleshoot.

I would replace the fresh food thermistors.

Thank you - that makes sense.

Question - my model (zisb48dyb) doesn’t seem to have a part labeled thermistor (I was assuming something like this: http://www.************************.com/PartDetail/Thermistor/WR55X10025/914093).

Looking through these pages (http://www.appliancepartspros.com/fresh-food-section-parts-for-ge-zisb48dyb.html) I find the following:

Is it one of these that needs replacing?

The thermistor is wired in the damper control, so instead of replacing it, just replace the thermistor. Get it’s part # in the sticky above and info on it’s resistance at room temperature so you can test it.

Sticky, ( GE refrigerators ( GS* and PS*) models.

The part # is AP3185407

Richappy - got the thermistor and took apart the damper. This looks like a sealed unit where the coiled sensor feeds into a bellows of some kind that expands to drive a probe to push a switch (cooling on/off?).

I do not see how to replace the sensor with the new style thermistor. Is that possible, or is my appliance too old? Do I need to order the full damper unit?

Pix attached…

So there is no thermistor in the damper package. If so, you will need to study the breakdown diagrams to find it.
