Hello from JA
My name is Woody.
I will be glad to assist you today.
I have been servicing ALL Major Brands of Appliances for 35 Years,
and have over 100,000 in home repairs and over 80,000 internet repairs under my belt.

Can I please have the Full model number of the unit to better assist you ?

You are missing the last number off the model number it ranges from 0-9 like FFU12F2HW7

Customer: replied 1 year ago.
Im using my receipt to get the model #.. just looked at the freezer and cant find any other numbers
Customer: replied 1 year ago.
is there somewhere I can look?
Expert:  Whrlp Master Tech replied 1 year ago.

ok I will use the 7 then !

This model has a mechanical defrost timer that is nothing more then a clock to advance it into ant out of defrost .

Lets pull the unit out and manually advance the timer knob till the unit stops running .

At that time the unit should be n defrost ,and then wait 5-7 minutes and open the door and listen for any popping or sizzling as it water is dripping on a hot object

Here is a part break down the timer is item # *****

Let me know if you hear the sizzling or not after 7-10 minutes

Customer: replied 1 year ago.
Advanced the knob and the motor stopped... I immediately hear some popping... maybe not sizzling yet but will wait the 7-10 minutes. Is the frozen food going to thaw?
Expert:  Whrlp Master Tech replied 1 year ago.

no it will not get that warm in the interior of the freezer only behind the rear interior panel will be the heat.

This will tell us if the issue is the timer ,not advancing into defrost or if it is the defrost circuit inside the freezer behind the rear interior wall.

Customer: replied 1 year ago.
I think its been 10 minutes.. no popping and sizzling sounds when I open the door :-/
Expert:  Whrlp Master Tech replied 1 year ago.

ok do you have a Volt-Ohm meter and know how to use it?

To be able to do any testing.

And the shelves and the rear interior lower panel will need to be removed so w can manually defrost the ice.

Customer: replied 1 year ago.
Checking on the meter... I will prepare the lower shelves... my sister has a freezer down the street I could put food in.. Kind of a I best off emptying all the food or just putting it on higher shelves?
Expert:  Whrlp Master Tech replied 1 year ago.

you can leave it in the unit and put it on the upper shelves and on the counter you will not have it out for more then 20-30 min so it will not defrost ,if nothing else cover it with towels to insulate it

Expert:  Whrlp Master Tech replied 1 year ago.

Once you have the food moved around and the rear interior panel ,let me know

Customer: replied 1 year ago.
My husband will have to look for the meter... he thinks we have one and he does know how to use it. He's looking and I'll move things around..
Customer: replied 1 year ago.
Ok.. Bottom two shelves are empty
Expert:  Whrlp Master Tech replied 1 year ago.

ok and if you have one later we will need a hair dryer to defrost the built up ice also.

Customer: replied 1 year ago.
ok.. found the meter.. seems to be a small amount of water leaking under the fridge. I dont have a hair dryer but i have a heat gun
Expert:  Whrlp Master Tech replied 1 year ago.

oh a heat gun is even better.

And if you have any water coming from the unit it may be defrosting can you still not hear any sizzling and or see a orange glow from that rear wall in the freezer?

Customer: replied 1 year ago.
No sizzling...we can hear dripping when the door is open..
I found the model # ***** the last digit is 8
Expert:  Whrlp Master Tech replied 1 year ago.

ok on the #8 and is the frost really built up it may be surrounding the heater?

Customer: replied 1 year ago.
no glow.. there is a sound when I stick my head in the door but it really just sounds like dripping.. the frost is melting and I have not applied heat.. should I?
Expert:  Whrlp Master Tech replied 1 year ago.

yes start at the bottom and go up!

Customer: replied 1 year ago.
The frost was not "really built up" I would say 3/4 to an inch if that.. is disappearing quickly.. applying heat now
Expert:  Whrlp Master Tech replied 1 year ago.

ok if it is disappearing on it`s own some thing has to be melting it.

Customer: replied 1 year ago.
I'm needing a big towel on the floor to soak up the water.. my husband has the volt-ohm as well
Expert:  Whrlp Master Tech replied 1 year ago.

ok we still need to verify if the unit is heating itself or not first if you can.

Customer: replied 1 year ago.
how should we do that?
Customer: replied 1 year ago.
can hear a sizzle now... used the heat gun for a minute or two now we're definitely hearing a lot of sizzling
Customer: replied 1 year ago.
should i keep the door open?
Customer: replied 1 year ago.
All frost is gone
Expert:  Whrlp Master Tech replied 1 year ago.

ok no go ahead and put the rear panel back on it will defrost itself ,now that we know it is heating .

That means the defrost timer is just not automatically advancing into defrost .

And the defrost timer will need to be replaced.

Expert:  Whrlp Master Tech replied 1 year ago.

Customer: replied 1 year ago.

Customer: replied 1 year ago.
