You are correct, my bad, I did not see that listed the first time, this is a newer style I have not come across as of yet with both.

Here it is:

Frigidaire 5303918776 Thermistor (AP6041625) - AppliancePartsPros.com

In SYSTEM DIAGNOSTIC MODE do test 39--->Freezer Evaporator Thermistor

Jake

Thank you!

K so I did the following tests:

• test #2 (frozen defrost heater). I turned it on and waited like it said and it did not increase temperature. it kept flashing 95 deg F
• test #29 (FF thermistor). it showed 48 deg F and my thermometer confirmed it but the fridge is set to 38 deg F
• test #30 (FZ thermistor) it showed 10 deg F and my thermometer confirmed it but the freezer was set to 2 deg F.
• test #39 (freezer evaporator thermistor). it shows 95 deg F.

Then that freezer evaporator thermistor must be the culprit its reading way too high.

appreciate it.
I think the heater defrost might be as well because even if it do a force defrost. the temperature doesn't change.
if i do test #2 and turn the heater on, the temperature doesn't change and the tech data sheet said it should increase. well, I guess the thermistor could be busted and it wouldn't be showing that.

all the parts

5303918776​

are sold out.
do you think these would work?
Amazon Frigidaire Thermistor

 

[Jake]

I have no clue, sorry, I've never ordered parts from amazon.

That amazon thermistor part number does not match though for the one you need.

Jake

 

[jtstp17]

right. all the

5303918776​

are sold out everywhere. I don't think they make them anymore.

So I wonder if another similar fridge thermistor would work.

 

[Jake]

Yes, I noticed they are out of stock everywhere, so its a waiting game now. Hate to to see you install one that's not for your model.

That I don't know, sorry.

Appreciate the reply as always.

I opened it up again yesterday. I checked the replaced defrost thermostat while it was frosty and it had continuity.
I defrosted the coils with a hair dryer. I switched out the defrost heater assembly even though it passed continuity as well.

I went to swap the defrost thermistor (with similar model) but the wire harness was not accessible. It just went up from the freezer and towards the back of the fridge. I have no idea how to access it. So, I guess the only way to replace it is to cut the wires and then wire nut the new thermistor to the cut wires.

I could not for the life of me get the defrost heater to heat up. I tried the force defrost setting, I tried the tests, nothing. The only thing I could thing of is that the thermostat wasn't frosty but you would think even a forced defrost setting would override that.

I am definitely worried that something isn't going right with the heater actually heating up.

That's exactly the correct way to do it.

You mean the evaporator thermistor? No, you usually can't override that, it have to be frosty or in a cup of ice water for at least 5 minutes.

Jake

 

[jtstp17]

No the actual defrost heater assembly. it is not heating up even if i use the forced defrost setting (plus and minus buttons at same time).
I even tried the forced defrost setting when the coils were frozen so the thermostat was definitely frosty.

but both pass the ohm test.

 

[Jake]

No the actual defrost heater assembly.

I see now, did you check for 120 volts going to it when it should be heating? if not do that first.

Jake

 

[jtstp17]

I didn't check any voltage. I unplugged the thermostat and checked for continuity and unplugged the heater assembly and did that as well.
I replaced both heater assembly and thermostat but not the thermistor.

forced the heater assembly into defrost mode when thermostat was frosty although thermistor said it was 90deg and i felt no heat off the defroster heater assembly.

 

[Jake]

You have to check voltage to it, then trace back if your not getting 120 volts to it.

If you are finding this a bit overwhelming, then Its time to contact Frigidaire to come out at 1-800-374-4432 to see what's going on, to see why this is happening, and if the Frigidaire tech does not know, they have a special factory hotline phone number to get the Frigidaire factory involved to find a solution to this problem.

In fact we are going on 2 months on this thread here, and its getting a bit overwhelming for me when it drags on this long, so its best to have Frigidaire come out at this point. There is nothing more I can help you with, sorry. Its not that I'm giving up on this, but its what I can't see 700 miles away from you.

Jake -

No worries. I understand.
I had a local technician come out today. He said everything is working part wise and that the control board is the culprit most likely. Just wanted to update you.

Do control boards really go bad that often for the defrost controls?

 

[Jake]

Thanks for the update!

Yes, that is correct, if the heating element and freezer thermistor ohm test good, then only part left is the main control board, which I posted the link to in post #11 here:

I have a frigidaire french door gallery fridge. It made a few crazy noises over a couple months and then we realized the fridge portion was warm. I put a thermometer in there and sure enough, it was 50degrees and our temperature was set at 35. The freezer portion is spot on and is cold. I...

No, very rare, but can happen especially if you live in a area where the power goes off a lot, its when the power comes back on is when you can get a power surge/power spike and it tends to mess up the control board.

That's why I always advise my customers to have a whole home surge protector installed at your home breaker box.

Damn. that would be smart for surge protector.

weird thing happened. the fridge is working this morning. went from 50 deg back down to 41 today...

[Jake]

Did the new control board fix it?

Jake

 

[jtstp17]

No it did not.

It is the freezer thermistor. But, it is backordered everywhere.

Although, the fridge is working but 3x a day I have to hold the up and down arrows and go to test number 2 and turn it on. The evap heater setting.
So fridge has not frosted up since early august.

I asked the techs if we could use another thermistor that looks similar and they said no. Not sure if that is true or not.

 

[Jake]

Ok, thanks for letting us know.

Hopefully the new freezer evaporator thermistor will be in-stock again very soon, I'm sorry to hear its been on back-order for so long, I don't know of a substitute one that would replace it.
