- How to test the evaporator fan in your refrigerator. If this fan is not running, your refrigerator will not cool.
The fan in the freezer is what forces the air down to the refrigerator compartment. If the fan is not running food in the freezer will not freeze and the food in the refrigerator section will not get cold.
This video will show you how to test the resistance of the fan and also how to check it for proper voltage.

Rip brother, you have blessed all of us. You live forever in our hearts ❤️ 🙏
Thank you for this. Just tested my fan and it spun very slowly. So I have a replacement in its way.
I love you so much for this. Thank you
shouldnt you explain what's a good ohms reading and what's a bad one? like what it means if it's too low or too high?
Yea, wtf? Giving one side of the story is worse than no story.
I was thinking the exact same thing, short and to the point but what is a bad reading?
What should be the resistance reading if it's a 12v DC motor, which is what mine has?
Hi, Bill,
I like your video!
Please add one more check point at the very beginning: Determine what voltage rating of the fan motor, then proceed with either 120V or 12 DC. They are not universal and not compatible with each other.
Thanks for uploading the video.
After the ohms test, you should also test the leads to the metal body of the motor, in case the windings are shorted to ground. When you test run it with 110v, put wire nuts on the wire ends, to make a good connection, and plug the cord into a power strip, so you can switch off the power quickly in case there is a problem.
Thanks fir video - I thought evap fan motor was bad on basement 20yr old fridge - I saw it not running when checked couple days after bad lighting storm came through - We lost power for 24hrs for down trees - I think might have had surge as some ground fault or arc breakers trip- Compressor condeser fan runs. Maybe there's circuit board somewhere I dont have any paperwork / diagrams - I thought being 20yr old probably just had defrost timer? Guess have to investigate some more- Thanks for making video- Just an old hillbilly shade tree type trying to save couple dollars-
What are good and bad readings? Is it the same for DC evap motor?
What's the reading for a faulty fan?
For the ones asking question in the past year, Bill pasted ago few years ago. Search past comments the answers could be in there and keep watching his videos and hopefully they will stay up. I'm not related just a DIYer who learned from videos and read past comments to find out about him.
Thank you for the info
Hey how are you. I learned a lot from your videos thanks. I have a 12volt 3 wire evap fan from a panasonic fridge and wanted to know how to test it. Thanks again.
i have a weird problem with the evaporator fan in the Amana refrigerator. I turn fridge on and the evaporator cools well and ice starts to form as expected cuz the door is open but the fan will NOT run. I noticed the defrost thermostat is attached to the cables that control the power entry to the fan. IF I bypass the cable that goes to the thermostat the fan works, IF I connect as it was the fan will NOT operate. Do you think it may be a bad defrost thermostat? I do not know
how to test the thermostat...I dont have a voltage meter. THanks for your reply. Roberto. in Miami.
I open the pannel of evoprate fan pannel... It's not on... But I externally check the fan is working with 12 v adopter.... But not working in refrigerator... I think problem in wiring or it's 12 volt supply... please help me... what to do...???
I tested my fan and I am getting 30 ohms but it keeps dropping to about 15ohms I think eventually it will goto 0 but I did not wait... does this mean my evap fan is bad ? I see when you test your fan its at 97ohms and sometimes even 100ohms and it should not go down ? will the control board stop a half working or almost dead fan from starting and thus giving me a error code..67 on temp display panel: failure of BLDC fan motor at freezing compartment , poor motor , hocking to wires of fan, contact of structures to fan. snapping or short lead.. I see the evap fan run during startup and about few mins in and it will stop completely and thru the code 67.
good one, bill...
I have a Whirlpool freezer model ev171nyms04, it's icing in the grill area and the fan motor not running. I checked the evaporator fan motor it looks to be bad when I test as show in your video using the volt meter omes setting. I have two question:
1. How can I ensure there is nothing else is wrong?
2. Fan motor for this model is about $100. Can I use any other freezer evaporator fan motor with the same voltage that is cheaper?
Thanks,
My fan just stopped this evening without any noise or signs it was going. I see when the fridge starts the fan does a tiny jump then nothing. I checked the wires going to it and 122 volts ac. I check the continuity of the motor and 0L, so I then checked the ohms of the motor where it is measuring around 2.2-2.4 megohms.
Is there a way to tell if the fan is going out and just hasn't gone out all the way yet like say its still getting continuity but its intermittent.
You cannot easily test new fans they are 12 Volt and have 3 pin connector with some electronic board inside the fan. The only reason they replaced the old fan with this new fan is that old fan costs 20 $ while new fan costs 160$ .all comes from consumer pocket.
yup
Awesome dude!
the yellow ,blue and white wires how can I wire it up for a fan for something diff. ????
So I have a fridge, The freezer is ice cold fridge wasn't. I had some ice build-up in the channel that lead to the fridge. After clearing the build-up out, I can now feel air going into the fridge. But after 8 hours the temperature of the fridge has only gotten down to 50Degrees, does it normally take this long to cool down ?
Karel2015 I think it needs 24 hours. Any updates. I have the same problem
Did temp improve after more hours after clearing the channels of ice?
good job. by the way what is the function of refrigerator fan?
I have an old fridge that has problem with defrosting! I have to shut it down and manually defrost it every 2 weeks or so, and I was thinking if I modify it by removing the defrost components (they are useless anyways in my case) and and wire the fan directly to the mains in order to make it working constantly even if the compressor is off! will that help to reduce the over freezing? because there will be constant air pushing which may help melting the ice! I know I will still need to manually defrost it from time to time, what I am hoping is to do it every 3 weeks for example instead of every 2 weeks! will keeping the fan on all the time help? thanks
Did the permanent fan thing ever get implemented? Did it have good results?
I have a GE bottom freezer double door refrigerator, model # GFMS5HFFA SS and I'm trying to determine if I need to buy a new evaporator fan. I have noticed that the refrigerator section warms up because the fan in the freezer is not blowing cold air up. It'll work fine for 5 or 6 days and then stop working. I should note that the freezer continues to stay cold and works fine.
The weird thing is that the problem comes and goes. I have determined that If I unplug the fridge for a few hours and plug it back in the fan works fine and cools down the refrigerator and both the freezer and refrigerator function as designed...and will sometimes work fine for several days and then suddenly the refrigerator is warm again...because that little fan in the bottom is not going.
My question is if the evaporator fan goes completely it probably wouldn't fail and then start working fine after a period of rest. Are these fans known to work for several days and then suddenly stop? Or do they just go completely? I don't want to spend more than a hundred dollars on a new fan if the problem lies in the control board or thermostat. I do not have the expertise to check those parts...but I can quickly and easily change out the evaporator fan...if, in fact, it is gone.

Any updates on the resolution of your problem with the fan?
thanks for that. my fan spins freely when theres no power, but when turned on it doesnt turn, and if you try and spin the blades, it will turn a quarter turn and stop. theres a magnetic force there acting on it. im gunna disconect the wires and do what you did and see what happens
You have power after you plugged it in to AC Power source, therefore your reading is your power source not your fan
tip of the day, don't touch the multimeter leads with your fingers when doing a measurement. Your body has some resistance and will not give you an accurate reading this way, it's a small increase on the reading....but, now you know....
actually it will give a slightly lower reading but i doubt it will change the diagnosis on this test.
Bill, my parents have a LG refrigerator with an on the bottom freezer. The lowest the freezer temps have gotten lately is around 20-25 degrees. The fridge stays around 36-38 degrees. What could we check to get the freezer colder? It isn't making ice either anymore. Thanks! We really like your helpful videos!
Bill Please help.. What would caz a good evaporator fan not to ever kick on? It tested good but wont work in fridge. Great videos, Thanks
Control board is the problem
What was your problem/solution? Thanks
@@TheJesseGuerra I got a new refrigerator..
@@terricorbin3513 Thanks for reply.
Is the ground wire suppose to be connected when the fan is installed. My fan is not working and I noticed it is not grounded
Omg lol. Are you trolling or serious? Plug the fucking ground in lol.
Pls help, a Samsung refrigerator, fresh food section not working, while other areas are. changed the fan motor, and the sensor still not working. found out the fan after changing is still not running. what should be the problem?
Please provide update? What was the problem if not the evaporator fan.
fan not running .... fridge stays cold ... freezer stays cold .... goes into defrost cycle ok ... fan comes on after a long time 12-14 hours ,,, top mount freezer model ... if the fridge goes down a bit , then fan goes on .... is this normal ???
Recently I have heavy frost and frosty icicles all over the food in the freezer and the walls inside the freezer, the seals were OK and door was properly closed. Can this be a sign the fan is bad?
Was the fan the problem in your case?
@@TheJesseGuerra Yes I changed out the fan and freezer was back to normal, but I noticed the same icing-up when I had too much food packed in the freezer sort of blocking the area around the fan.
when i conect to refrigerator fan is not working its problem with viring butt i cant find the board in refrigerator
Not recommended, but you take yer jumper cables from the truck, jack a conductor into both prongs of a 120volt outlet, connect that to the fan. If she runs she’s good. If ya got a big blue spark, that whole mess is gonna catch on fire if ya don’t trip the breaker.
my evaporator fan is running,,,,,,,,top of line to evaporator frosting up to the point where line is wrapped in black tape,,,,,,,,but below that to evaporator nothing frosting up ,,,,,,,do i need a new evaporator ?
+bob woerner Freon restriction or loss of freon is what it sounds like.
worth fixing ?
I connected the AC like you did and got a loud "pop" and a blue flash...
I personally thought that part of video was questionable. Glad you are ok.
I mean when testing the motor with 120V, is it necessary to ground it?
Hello bill my microwave is totally dead it does not go on
HI Bill,
Question: my samsung freezer fan has 3 wires red, black and white. What is the extra wire for?
Thanks for all the videos. It's a 12 volt DC motor.
Filler Wong
I have the same motor problem.
What did you find out?
Black is ground
Hi Bill,
Great video, very well explained and shown! I have my LG refrigerator evaporator fan out and want to check it the both ways you said. Mine has a white, pink and gray wire coming out of the transformer. Could you tell me which ones I need to attach to the probes to check the ohms and A/C cord to? Thanks, Joe
Is the fan grounded?
Meow Mix When it's in the fridge it is.
