Randy 43 :

hi, you had frost on the back panel of the freezer section?

JACUSTOMER-v76vawvf- :

no

Randy 43 :

the fan is in the freezer section correct?

JACUSTOMER-v76vawvf- :

There is a little ice buildup in the back of the freezer. If there is only one fan, it is in the freezer section, yes.

Randy 43 :

ice buildup on the rear panel?

JACUSTOMER-v76vawvf- :

yes

Randy 43 :

you didnt have that rear panel off right?

Randy 43 :

but you can verify the fan is running?

JACUSTOMER-v76vawvf- :

No, I have not taken anything apart.

JACUSTOMER-v76vawvf- :

Yes, I can hear it and see it moving when I look at the back of the unit.

Randy 43 :

in the fridge section at the back center there is a grill..the center snaps out, this is the fridge damper ,can you see if it is open?

JACUSTOMER-v76vawvf- :

yes it iopen

Randy 43 :

slight frost on the rear panel is a sign of a defrost issue in behind that panel

Randy 43 :

it will be more heavily frosted, causin no air flow to the fridge section

JACUSTOMER-v76vawvf- :

I don't see any frost in the fridge panel.

Randy 43 :

3 components in the defrost circuit, heater, thermostat and main board

Randy 43 :

no, the frost in the freezer section

JACUSTOMER-v76vawvf- :

What about the frost in the freezer section?

Randy 43 :

the fan in the freezer draws air across the coil in behind the freezer panel blows it thru the damper up in the fridge section

Randy 43 :

you have confirmed the fan is ok and the damper is open

JACUSTOMER-v76vawvf- :

Does that mean it is frozen up in the freezer section?

Randy 43 :

frost on the back panel indicates a defrost issue, one of the 3 components in the defrost circuit are defective

Randy 43 :

yes,it is frozen but it will continue to happen unless fault is repaired

JACUSTOMER-v76vawvf- :

So what is the short term and long term fix?

Randy 43 :

heater and thermostat can be checked for continuity,if these are ok ? the problem is in the board

Randy 43 :

heater and thermostat are in behind that freezer panel

Randy 43 :

board up in fridge section at top/front

Stepped out? Coming back?

Randy 43 :

im here

JACUSTOMER-v76vawvf- :

What is the next step?

Randy 43 :

any questions? i dont know your mechanical ability? you would req a meter and be able to remove the rear panel to access these parts, but one of them is open causing the frosting, usually not the heater, i would suspect thermostat,then board

JACUSTOMER-v76vawvf- :

In order to get it to work now I need to turn it off and defrost the freezer, correct? In order to resolve this issue permanently I need to fix the problem with the board?

Randy 43 :

yes, you would need to defrost it , but it isnt necessarily the board, it is one of 3 parts i mentioned..you have a defrost problem but the 3 components need to be checked for continuity to see which one is defective

JACUSTOMER-v76vawvf- :

Are these normal warranty items? This fridge is only about 3 years old.

Randy 43 :

no,they are covered for only 1 year, but they are a lot less inexpensive than a compressor or sealed system repair would be

JACUSTOMER-v76vawvf- :

Ok. thanks.
