TOC for the dryer goes open circuit

Miele WT2680

Hi, the TOC  for the dryer goes open circuit about once a month.  I have replaced the temperature limiter for a new one but it still happens.  Have Miele increased the temperature rating of this component.  Thank you for any help.

Hi. It may be responding to overheating. The fan not running or it’s blocked, or a blockage somewhere in the condenser chamber, or if the trickle of water into the condenser chamber has stopped, all these faults can cause it to over heat. 
 

On the other hand they should all stop the dryer from drying properly too. So if during the time when the TOC is still working the dryer works perfectly then that would imply none of the above faults are present.

Thanks for the reply Andy, that is helpful.  I have dismantled the dryer and checked the fan etc. I will carry on with the fault finding and let you know what I find,

Hi Andy,  yes I did read the article, thanks.  I have now discovered that the fan intermittently starts.  I have dismantled it and there isn't anything clogging it.  On checking the price of a new part have decided to scrap the machine.  Thanks for your help.

Thanks. I presume the connections and wires leading to the fan are OK.

Hi Andy,  yes it's definitely the fan. I am a retired television engineer and the electronics are not a problem for me.  I am disappointed though, the machine has not had excessive use and the washer part is still fine.  However, thanks again Terry.

It's a shame for sure. It'll still work fine as just a washing machine but if you need a washer dryer that's that.
