Printed Circuit Board Repairs for Tumble dryers AEG, Electrolux, Zanussi Etc
Even if you’re not a technician or an engineer, some Tumble dryer printed circuit board problems are obvious. Some common and simple problems can cause a printed circuit board not to work.
A thorough visual inspection of your tumble dryer PCB could save you having to buy a new board they can cost over £150 plus a needless engineers bill. Don’t be afraid to have a look. Just make sure your power is turned off to make sure you don’t get an electric shock.

Hello,
Thank you very much for your repair guides. I repaired our tumble dryer AEG Lavatherm just like in your video and it was working! Unfortunately after several month another may by common fault appear the error code E50 and then error E5E which means the problem with motor board communication unit. I removed the motor board unit and found out that the linked switch LKN364GN was destroyed and another resistor R118 was burned out. This issue is described here but there are still no information about the resistor R118.
Please if you can find out this information I think not only me would really grateful. For example if you have the possibility to photo the new motor board.
Thank you very much again.

Hi,
Bee reading through you site and hope I can get some help like others have. I have an Electrolux tumble dryer with the motor inverter board 136005602 ELEW011. The only “visible” damage is a small smd resistor (R118) right next to the bridge rectifier burned beyond recognition. Do you have the value of this resistor? Thanks in advance.
I’m sorry I don’t know the resistance of all the individual chips all I can suggest is see if you can find a second hand circuit board on eBay.

Hi, there is 100 value printed on the resistor R118 so it should be 10 ohms. Here you can see .
Cheers.

Hello!
I have found your article searching for information on ENV06 repair. I have a tumble dryer Electrolux which starts to spin 4 or 5 times and then stops with error E53 ( triac sensing circuit fault ). I cannot seem to find any component which is burnt/broken/not functioning! Yet, the dryer does not work. Do you have some advice on what else to check ? Direction change relay is good,and the triac sensing line which takes one output from relay through 3 pcs series resistors 470k is also ok. Also do you know the markings on triacs,specifically the triac for drum rotation motor, I think it is ZR0405MF,but the markings are barely visible.
Hi,
Thank you for the tips, very helpful !!!
Unfortunately I’ve broken a transistor while desoldering the LNK304GN and I can’t find infos about it to replace, would you have any ideas about spec that it could be? it’s near to the right of the LNK, there is two of them one beside the other and the enclosure of the transistor shows “JVW 07”. Can’t find infos ?? Way to find schematics?
I’ve took a pictures with microscope could I send it to you?
Thank you for your attention

Hello. Thank you for a good guide.
I have a AEG Electrolux Mod: TN55460, Type: P502664, Prod nr. 916 096 379 01
I was wondering what to look for, if I get error code E32?
I first got error code E54. Then I changed the capacitor, but got new error code E32. All red lights, and it will not even respond properly. I tried also to clear the error code, but I guess it was after that it stopped and I get error codes as as explained.
Now I am looking at the circuid board, but cannot find any cracks or dry joints. Tested some diods with mulitmeter, but they looking good.
Did not replace the LNK304GN 54526E yet. Could it be broken?
I see you have a repair guide here:

What is this chip called in the second picture?
I have a picture of is here:
http://www.evernote.com/l/ABkueSCjK_xBTI-IllKiGmwcTSHUXiMwUjA/
I tested also the temperature sensors, and they all look good.
The electric motor seems to work also, as its turning.
I also have to add that the water pump and the belt are OK.
Any good ideas what part is broken or needs to be replaces?
Thanks
Where can I get one of these resistors – mine is O/C – it says 47 ohm 10%
maplan may have them

Hi Paul
I have an Electrolux 67550w and i have 230v into the machine. The problem is that the machine doesn’t start and the diodlight is dead. I think that the Link Switch can be broken.I see a small melt on it.
Do you have this problem before that no diodlight lit?
Can it be the Link Switch?
BR Josef
the Link Switch is common also check all resistors
Hi Paul
I have Elektrolux EDC 67550 Drayer.
When I switch on unit all diode are dead ( and dryer no work).I replaced LNK 304 GN and resistor R76 47 Ohm but still diode are dead.
Which Voltage I need to have on LNK 304 GN .I make measurament and voltage AC and DC on LNK 304 GN no exsist.
What I can check ?
Rgds
Ivan
you also need to make sure all diodes are good and resistors
Hi,
Would any board issue cause the element to overhead (with error code E63). I have fitted two now both have tripped with E63 safety resettable thermostat tripping then a full TCO trip. Could there be a fault on the board causing over heating?
Hi Paul,
I have the Electrolux 67550 it starts and stops after about 45 seconds with display returning to zero on timer. Strangely it will work on the “time” option. Cool/shoes/wool all seem to work but all others will fail. I had error 51, when I go into engineer mode initially I see code C7. Any thoughts?
Martin, i have the exact same problem, starting and then stopping after 30s with 0 on display. Will work in ‘TIME’ mode. Did you find out what the problem was? Thanks, Jo
Hi, i have the same problems drying tomble Electrolux EDC78550, it`s only run for 25 sec, before IT stop, and the display 00. How do you solved your problem?
What area of the PCB typically fails to produce an E68 error code on a Frigidaire Affinity electric dryer? I have checked the microswitches and all seem to be working properly, after reassembly the code is still coming up. Without any user interaction the dryer will occasionally light up, a couple of times the light for the dryness level cycled through the settings before the code came up.
Hoping you can save me time and money by pointing me in the direction to fix my board.
Thanks.
Hi Paul,
My AEG Lavamat Turbo 16850a has died and it is the LNK305GN, an inductor and the R76 resistor that says “33R 10%”. I thought it meant 33 ohm. I want to replace it with a 33 ohm safety resistor (for washing machines), but in your video you talk about a 4700 ohm resistor.
Do you happen to know if my 33R is indeed 33 ohm or is it 3300??
Rgds,

Hi Paul,
I have the Electrolux AEG 56840L . i need a number off the chip in the image 9/17. near LNK304GN and is located between the R79 and C25.
As well as the appearance of the image lock prevents Drayer clothes work.
Thanks
Hi Paul,
I have Electrolux EDH97981W.. The same control boards. I found burned compnents on second PCB http://prntscr.com/cpxrrd.
Can anybody check what was value of this (probably) resistor? From Where to where it is connected? Any idea what could be reason for burning this resistor>
Thank you in advance for help.

Hallo Paul ik heb een aeg droger .deze stotterde steeds met opstarten .als ik een tik er tegen gaf ging hij draaien. Alle verbindingen zogoed als opgefrist
Nu start hij wel maar met autorevese gaat hij stotteren .welk onderdeel regeld de autorevese van de moter?
if Google translate is working correctly I think you are telling me you have a problem with the drum not turning in One Direction, this may be a fault with a relay on a circuit board.

Hi Paul,
thank you very much for this interesting article. I have a AEG Lavatherm T59850. While I was working, it suddenly stopped and died.
Following your instructions, I inspected thoroughly the PCB and found only the 47R resistor broken. I ordered a new one along with the diode TRSB1 (the components I bought are identical -even from the same manufacturers- to the original components).
I replaced the resistor and the diode (even if the original one appeared working well) but unfortunately the resistor blown again. The LCD panel didn’t show any sign of “life”. As soon as I turn the knob, the R47 resistor blows. Do you have any suggestions on what to check?
What could be the problem?
Of course, if you help me solving this problem, I would be more than happy to offer some beer!
Thanks
Hello Giuseppe
You mention the diode at TRSB1.
Do you know the full specification of this part as there are many different diodes. Also, do you have a link to purchase this diode?
Regards
Hey Paul,
I have an AEG with ENV06 that will not turn the motor. Usual suspects like brushes, tacho and motor itself have been eliminated, I suspect a fault in TRIAC control circuit. Any pointers?
Hi Paul
Great video and very useful pictures etc. – thank you.
My Zanussi tumble dryer has just stopped working and will not even ‘turn on’.
I have removed the PCB and can see that the resistor R76 has a small crack in it (almost as per your picture). Do you think replacing this will fix the problem? Also do l need to replace the link switch as described – it looks undamaged and there are no signs of any sort of shorting!
Where do you recommend l purchase a new resistor (47r 10%) to replace the damaged one?
Any advice to can give would be gratefully received.
Regards
My tumble dryer Electrolux Model EDC67550W suddenly stopped working midway. I checked fuse and all connections but could not switch it on. There is no light. Please help.
