My Whirpool refrigerator/freezer model WRT318FZDB01 is not cooling. .. mostly just the freezer, but i can tell the temp is rising in the fridge part too.
In the freezer the dial in the back, i think that is supposed to control the temperature. i guess it was frosted over, because when it began to thaw it just fell right off.
I have never had a freezer like this, where i guess it relies a lot on the air flow in the back of freezer, and fridge. and i keep noticing, it can be pretty hard to not block those vents or what not. but as of now, they are not blocked at all. Last night it was making a loud noise, so we pulled the whole thing out, unplugged it, and i vacuumed the coils. i thought it was doing ok until i noticed my ice cream was still mushy. and the ice trays were not freezing. (we do not have an automatic ice maker)
i tried reading a few threads on this site but i am afraid to tinker with anything seeing how none of them matched my exact refrigerator.
i must add, this happened about 2-3 mths ago. we eventually took everything out of the freezer and fridge. (the whole thing was not cooling) and defrosted it completely, and i cleaned the coils the best i could with what i had available. that seemed to work great, until now. so could it be a defrosting problem? also the fan next to the coils is working. im not sure what the compressor is, or where its at, but that semi large metal round thing next to the fan is hot. and i heard absolutely nothing going on in the freezer. sorry, last thing i have to say, the entire time we have had this fridge the refrigerator part of it freezes everything unless its in the door or down in the drawers. my husband likes that about it, but i know that this is happening for a reason and it is not supposed to. could this all be related? and how can i fix it, myself?
thank you so much

Hi,

Rick may have missed your last reply.

Here's the parts diagram for your model:

So do you notice frost build-up on the back panel inside the freezer? Have you already remove the back panel inside the freezer?

Here's the evaporator thermistor for your model:
WPW10384183 Thermistor


I asked our tech bigbuck if he could please post your tech data sheet, then we can see what it should ohm test at.

Here's the video to show you where its located:

Yes jewels, keep posting here so Rick and I can help you.

So do you notice frost build-up on the back panel inside the freezer? Have you already remove the back panel inside the freezer TO SEE the frost build up?

Look at these photos below, which one does yours look like when you have frost build up on them?

sorry its taken me so long to respond, yes im still fighting the defrost problem with our freezer, and yes we have taken the back panel off and i believe the first 2 pictures are the most similar to how mine looks when it freezes.. if i had to choose though i would pick the first one.
i will try to get a picture for you today.
oh i should probably add that i can not hear the fan running anymore. we were able to defrost it once again about 1 1/2- 2 days ago, and ever since i noticed the ice isnt freezing and i am not hearing it make any kind of sounds. but the fridge is still cool. and the freezer is also cool, but im not sure how long i will be able to say that.
any thoughts?

OK jewels, this is what you do; First, unplug the refrigerator and access the control in the fresh food section (2 screws). Set your meter on the lowest ohms scale. Disconnect the wire connector on the control and measure the resistance between the white wire and the brown wire in the connector. Your meter should indicate 30-40Ω. Measure the resistance of the freezer sensor. Make sure your meter is on a high ohms scale RX20KΩ. At room temperature your meter should indicate 3.1K to 3.3K ohms.

If your meter shows an open circuit or 1 across the white and brown wires, remove the evaporator cover in the freezer. Use a hair dryer and completely defrost the evaporator. Make sure there is no ice or frost on the evaporator. Measure the resistance of the defrost heater. If it reads open replace it. If your meter shows 30-40 ohms replace the control. When your done defrosting it plug it in and check that the fan is working. Replace the cover over the evaporator. Do not leave it off. The refrigerator will work properly until you replace the bad part. Longer than a week and you'll need to defrost it again.

ok, the fan is working again. apparently that problem was just putting the backing of the freezer back on incorrectly.
does that change anything from your instructions on what to do above?
and im guessing i need a multimeter to do this??

Hey I have some better pics for you
This first one, my husband had already defrosted it but I believe it was that black rectangle piece he says was completely iced over and took forever to thaw out.
As for the multimeter, I only know of them cause harbor freight had a coupon once years ago for them. But idk anything else. Is there a specific one I should look for? As for using it I guess I can Google-tube it...
Back to the pics, I dont know what angle I was trying to get in the first one. But the 2nd is pretty self explanatory.
I guess I'm just trying to get as much input as I can, so when I do order the part I dont order wrong and we can get this done right the first time. Thank you for all your help..happy holidays

If you plan on doing other repairs a DMM is the most important tool in your tool box. DMM's start at about $10 at any of the home centers or walmart. You want one that can at least measure AC volts, DC Volts, and ohms. They're easy to learn and will take you about 30 minutes. This one has everything you need plus, and costs less than $20:

ok, i bought a multimeter it says it measures ohms, but it only came red and black cables, and not the white ones like the picture above.

You got it from RC and it's missing? Call repair clinic and tell them. They will ship you the missing parts.

Please take the 30 minutes and learn how it works first. Do a few practice measurements. Set it on AC Volts and check a few wall outlets. Set it on DC Volts and check all those batteries in a drawer somewhere. Set it on resistance / Ω's and check all those lightbulbs in the other drawer..lol
