Can an old fan work only at times? Is there a way of cleaning it? Could it be the temp sensor instead? I don't recall this guy testing it, but he says he followed all the tests in the service manual.
Fridge bros?
Replace the fan.
There are no spares anymore.
I can have it cleaned and greased. But I don't know of a grease or oil that can stand subzero temps.
>There are no spares anymore.
You've had this fridge for 20 fricking years. You've paid or had warranty service to replace the electronic board three times now. If you had any PrepHole in you at all you would know everything about this fridge by now, and you would be able to use any damn fan you can find to replace the one that has "no spares", and you would know the electronic board so well you could replace the "burn triac" for $5. I bet you have never asked the guy to let you keep the bad board.
Oh wait, I might have to cut some plastic or make a housing or something to use a fan that does not fit perfectly. Just buy another $3000 refrigerator already.
Chill out. It is my boomer parent's fridge.
So I can't try experiments. I will only intervene in case of very evident and easy fixes.
>you could replace the "burn triac" for $5. I bet you have never asked the guy to let you keep the bad board
The bad boards are customer property according to the local law. Yes I could have replaced that component, but there are other chips (controller) that might have taken damage without any visual clue.
>I don't know of a grease or oil that can stand subzero temps.
There are actually quite a lot of low-temp greases available. A few I know if are Phillips 66 Moly Low Temp, SLC-400 cryogenic grease, Jet-Lube Arctic, SuperLube 21030 Synthetic grease, they'll work down to like -40 F or even lower. Most snowmobile suspension greases offered by manufacturers like Polaris, Ski-Doo, etc. have an extremely low minimum working temperature as well.
Also check the air slot between the freezer and fridge, could be full of ice. It's where the freezer moves air to the fridge.
That is the most common cause on 'not cooling'. But there was no ice block down there.
Coukd you post the model number? f it's a 20 year old fridge I'm going to assume that it has one set of evap coils in the freezer and none in the fridge. Does the freezer freeze okay? If the freezer freezes and the fridge doesn't cool then it's either the fan or and ice blockage. If the freezer does not get cold enough then it could be a refrigerant leak or restriction in the sealed system. I know this isn't much help and a lot of what I said has already been addressed. Just see if you can do anything about the fan or you really might as well get a new fridge.
Get a new one, it will work and be 5x more energy efficient than the one you keep dumping money into. I put a lock on and store ammo in my old one.
at what point are you going to realize you've spent on new parts what a new fridge would cost you?
> electronics: 110 bucks
>new fridge: 1200
It is working again btw.
It wasn't the electronics nor the fan.
Something might have clogged the drain.
>$1200 for a new fridge
if you're paying that for a new fridge you may be moronic
There are smaller models starting from 700.
"American" ones start at 3k.
I bought a new refrigerator for $300. You've spent more money keeping this piece of shit alive than just getting a new one.
