AEG Electrolux T35850. No heating

[jerry111]

This machine has been ‘not heating’ or taking much longer to dry clothes than before. There is no mains to either of the two rear heating elements. They read 51 and 36 ohms cold. I’ve taken the front control panel off and inspected both sides of the pcb, there are no signs of burnt out components etc. Is this likely to be a control pcb problem? I have read that the relays that feed mains to the heaters can give problems, is this possible on this unit?

There’s a lot of listings for thermostats for driers is this likely to be the fault?

When the unit is running all the led’s light as they should and the drum starts and stops as normal There’s no indication that anything is wrong except that the ‘exhaust’ is much cooler or not warm at all.

I work as a electrical engineer and take the usual precautions when testing.

Thanks for any help or advice offered. 🙂

Re my original post..

I’ve been able to read the error codes from the machine. They are as follows: Start/Pause LED flashes:6x amber-green, then 2x red.

During normal operation all LED’s operate as normal.

If I start the machine empty, it runs cool for around 2mins, then turns off. I suspect that this may be normal.

Both the temp stats under the heater elements measure OK.

Thanks, jerry111.

Hello all,

Managed to find the service manual on the internet which made things easier. In the test mode the drum rotated and I was able to turn on both heating elements. So began to think more control, or the main pcb 🙁

Before going down that route, I checked the resistance of the NTC on the front chassis. This measured about 800-1000 ohms greater than the spec in the manual. After ordering a replacement and checking the two side by side, the new NTC was around 1000 ohms lower than the old one.

After fitting and 3 test runs, the dryer is back to normal. 🙂

Regards, SJM
