Printed Circuit Board Repairs for Tumble dryers AEG, Electrolux, Zanussi Etc

Tumble Dryer Parts

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.

Make sure it’s unplugged from the electric supply, now check all the connections are good tight and the pins are clean as you can get corrosion build up due to moister. You can Remove the cover from your tumble dryer PCB.

If the previous has not cured your problem you now need to remove the printed circuit board from the tumble dryer facial panel. Dryer covers are held on with screws and clips; this can vary from on different manufactures and models of tumble dryer.

The first inspection should be to check all the tracks on the circuit board look for water damage and also burnt tracks, due to the nature of the appliance there can be quite a lot of humidity on the board especially if the dryer has been kept in a very cold room or garage. Condenser dryers are more prone to this than normal vented dryers.

You are having to go into the realms of Electronics and if you do not know what you are doing you can cause more harm than good. You need to check for signs of damage to Components like Capacitors, Resistors, Diodes, Triac’s and the link Switch which fails so often on this type of tumble dryer. (Please note that when the LNK 304GN u. TNY264G blows the 47R Resistor also has blown) and you need to check all the Resistors & Diodes. I have put together a load of pictures on these Env 06 boards so you can get an idea of what to look for.

These pictures will help you understand some of the common chips that blow and there not always obvious

If you are not sure take the circuit board to someone that does what they are doing!!
