Is It Necessary To Repair Yoder Loop

Topic: LG linear compressor failures (LG and Kenmore refrigerators)  (Read 2026 times)

Accept yous guys had any experience with the new LG Compressor TCA38091801?  Are they curing the chronic failures of the fridges?  or is it a temporary repair to a permanent trouble?  I have a Kenmore 795.74022 (2017 model) with the typical linear compressor failure.  I am currently evaluating my repair options.  Any thoughts/opinions would be appreciated.

From what I accept read the new compressors are working better but might be too soon yet to tell since the older compressors would final 3 yrs or and then before failing.
LG extended the warranty menses for parts and labor on compressors but since you are asking well-nigh a Kenmore/LG not sure near the warranty situation since it is not handled by LG yous take to deal with Sears.
The lath must be updated if you do the new compressor and there has been a firmware update for the jig so you have to make sure you have the newest version.
I heard you tin can download and update the jig with the newer firmware.
Older LG mainboards from 2022-2014 might non update with the jig and you take to call LG or order a new mainboard if it wont update.

Nobody knows, considering the new compressors haven't been out long enough to fail.

I but made a thread most this. I'll update this post when a mod approves it. Essentially I bought an LG fridge from someone that had LG replace the compressor two-3 times and the terminal time (being the new compressor model) simply lasted overnight. LG gave upwardly and just gave the owner half of the refund and voided the unit. I can hear the compressor working and the condenser fan is on but when I touch on the high side it does not get warm or hot. I'm not sure what's wrong. If anyone thinks they know, delight let me know.

> someone that had LG supervene upon the compressor 2-3 times

Whoever worked on it did a bad job.

The compressors aren't great, but there'south no way a properly washed repair should fail 3 times in a short period of time. It almost certainly has a leak/restriction/contamination/software or board update that isn't beingness handled properly.

>  I can hear the compressor working and the condenser fan is on but when I touch the high side it does not get warm or hot.

That'due south probably some sort of sealed organisation problem, just non necessarily the compressor.

If this is your refrigerator and you can go a good sealed system repair from a competent technician that does a lot of LGs, and y'all tin can get information technology done for free under warranty, I'd become for it. If it'south going to cost you money, I'd supercede it with something unlike.

I but made a thread about this. I'll update this postal service when a mod approves it. Substantially I bought an LG fridge from someone that had LG replace the compressor 2-3 times and the last time (existence the new compressor model) merely lasted overnight. LG gave up and just gave the owner half of the refund and voided the unit of measurement. I tin can hear the compressor working and the condenser fan is on but when I touch the high side information technology does not go warm or hot. I'm not sure what'due south wrong. If anyone thinks they know, delight let me know.

You cannot become help from LG on that unit anymore if information technology was voided in their system by the serial number.
If yous know how to do sealed system work you can endeavour to cut the filter drier out and cut belch tube from compressor and accident nitrogen through condenser see if it comes out past inlet to filter drier. I saw a post by a tech showing photos of complete blockage in the filter drier that was a solid tan gunk and it was even backed up inside the tubing coming from the yoder loop. You can bypass the yoder loop and replace condenser if information technology has signs of blockage but it might have passed droppings into the 3 manner valve and then into the capillary tubes (if it is a dual evaporator unit). If compressor overheated many times the oil gets gummed upwardly and clogs the organisation. Or if information technology had a low side leak moisture is drawn into the organisation which causes POE oil to turn into acids and solid salt compounds that travel effectually the system clogging everything upwards.

I've been an apparatus technician for 41 years and I don't retrieve e'er seeing so many bad compressors (big box store dehumidifiers excluded) as LG refrigerators have.  Two weeks ago, the we scrapped out 8 LG refrigerators, all with bad compressors and non one of them was four years old.  One calendar month ago we had a customer who spent several days endlessly calling LG over again and over again and LG finally agreed to replaced their compressor on their 2 year one-time refrig.

This by October I was doing a washer repair and the customer mentioned that their very immature LG fridge was going to take the compressor replaced in warranty but that the service appointment was nearly one month out.  They inquired if my shop could do the repair faster.  I knew we could practice it in simply a few days merely fibbed (considering information technology was an LG) and said no, we're backlogged likewise.  In March, just earlier the COVID-nineteen quarantine began, I was back at the aforementioned client's business firm to repair their drawer microwave oven.  They told me their LG refrig just went out again and wondered if the warranty serviceman had done a bad job.  I looked over the paperwork and discovered that I knew the tech (and he'southward excellent) who replaced the compressor.  So through no fault of their own, the warranty service company got a bad yelp review from that customer.  Sure am glad I fibbed and didn't do the chore or that would've been me.

I don't know if new replacement LG compressors are any better but currently we suggest when refrig shopping, pick anything only LG.

I�ve put in around 50+ now since they debuted. Oasis�t been back yet merely also hasn�t been iv years yet like nuance said lol. You simply take to brand sure you lot have the info replacing. You need the flash jig and also the compatibility list. Merely nearly all fridges will except the 801�s except the oem comps that are in the 300�s. Those have to have the OG comps. Merely had a 795 with the 300 comp. and those are rare though only 2d I�ve seen out of 100�due south but I�d still bank check.

viii weeks ago fridge and freezer both stopped cooling, LG sent a tech out who replaced the compressor, next twenty-four hour period but the freezer was working and the h2o and ice maker.  LG sent another tech a calendar week later who spent two and half hour doing IDK what other then him rechecking the get-go guys work, second guy said it should all exist cold in 24 hours, next twenty-four hours it was same, refrigerator nevertheless not getting cold. No codes appear on the front display and no blinking lights on the rear PCB board. When put in test mode everything functions as it should when it is put through the three modes. As LG has at present left us hanging we take replaced ourselves the Fridge Defrost Sensor Assembly. (it didn't help) then the "Full Duct Associates, Multi, ( that didn't help) then we just replaced the (Refrigerator Temperature Sensor, (which likewise has non helped. We are at a loss, don't know what to replace from here. Anyone have whatsoever clues???

eight weeks ago refrigerator and freezer both stopped cooling, LG sent a tech out who replaced the compressor, side by side day only the freezer was working and the h2o and ice maker.  LG sent another tech a calendar week later on who spent 2 and one-half hour doing IDK what other then him rechecking the first guys work, second guy said information technology should all be cold in 24 hours, side by side 24-hour interval it was aforementioned, refrigerator yet non getting cold. No codes announced on the forepart brandish and no blinking lights on the rear PCB lath. When put in test mode everything functions as it should when information technology is put through the 3 modes. As LG has at present left us hanging we accept replaced ourselves the Fridge Defrost Sensor Assembly. (it didn't help) and so the "Full Duct Assembly, Multi, ( that didn't assistance) then nosotros simply replaced the (Refrigerator Temperature Sensor, (which also has not helped. We are at a loss, don't know what to supervene upon from here. Anyone take any clues???

Take to check frost pattern of both evaporators. You said freezer is cold simply refrig is non so pull off cover come across if any frost on frige evaporator. You can also listen or feel cap tube inlet for flow of gas. And look for tiny crimp in the cap tube at inlet of evaporator. If you meet it cutting that crimp off and rebraze cap tube there might be junk clogging at the crimp from the failed compressor. Too accept heard nigh oil gets stuck in the evaporator clogging flow.

Hi Houptee
Simply changed out the primary command board yesterday and observed no alter, the evaporator in the fridge doses not go a frost design on it at all,
The freezer compartment and ice maker and h2o dispenser work fine.  I�m at a loss as LG has left me hanging going on 9 weeks now living out of a cooler and trying to supplant piece by piece as I research possibles, I�m pretty good at repairing appliances for a girl, repaired my oven, dishwasher, dryer and pretty much took apart my LG front load washer apart to replace the bearing when repair man wanted 700 dollars for a 25 dollar part on a 3 year one-time washer information technology took me 2 days and a few sweat words but information technology�s working just fine at present, these things seem to fall apart only later on their extended warranty ends, I had a five year on my refrigerator and it was just 6 months past....

Hi Houptee
But changed out the primary command board yesterday and observed no change, the evaporator in the fridge doses not get a frost pattern on it at all,
The freezer compartment and ice maker and water dispenser work fine.  I�m at a loss every bit LG has left me hanging going on 9 weeks at present living out of a cooler and trying to replace piece past slice equally I research possibles, I�m pretty proficient at repairing appliances for a girl, repaired my oven, dishwasher, dryer and pretty much took autonomously my LG front load washer autonomously to replace the bearing when repair human being wanted 700 dollars for a 25 dollar part on a 3 twelvemonth erstwhile washer it took me 2 days and a few sweat words but it�s working but fine now, these things seem to autumn apart just after their extended warranty ends, I had a five year on my refrigerator and it was just 6 months by....

At that place must be no refrigerant flow to the FF (fresh food) evaporator. This could be a clog in the capillary tube which is the sparse tubing that runs from the three way valve to each evaporator. Did they replace either evaporator when they worked on the fridge? Where the cap tube connects to the evaporators LG puts a modest pinch crimp in the tube and this can cause debris to get stuck and clog the tiny tube at inlet to the evaporators. Some other problem is when they replace evaporator the tech might accidentally braze the cap tube also much and braze it shut considering at that place is non much cap tube to work with later cutting off the crimp section. A rare one is the iii mode valve is bad and does non send refrigerant to the other evaporator (some techs that work for LG have told me they hardly ever have to replace a 3 way valve).
So the only thing you can do to effigy out the issue would exist to identify the three style valve in home position by unplugging fridge, wait a minute or so, plug it back in and you tin feel and hear the iii way valve vibrate and chatter, as presently as it stops vibrating you unplug the refrigerator. Now you can go over by the correct side where h2o connection is and there is a harness connector that you can unplug so the 3 way valve will non modify position and stay in home position. Now plug it back in and let it run for a while and see if both evaporators are getting frosty. If not then you pretty much accept a clog restriction to the FF evaporator.
You would demand to remove refrigerant and effort to cut out the crimp and then put nitrogen in the organisation and see if it blows out the cap tube earlier yous rebraze it to the evaporator.
This should accept been all done by whoever did the compressor job. It is a hurting in the ass working within the box trying to affix in there without burning the plastic on back of fridge.
