This Siemens ovens cooling fan keeps running.The Customer woke up in the middle of the night as she heard it on .She had not used it all weekend as she was away.Is this a module Fault?
Any help greatly appreciated.

Thanks for reply
Looked at this quickly yesterday.I tried disconnecting the 2 stats on top but figured the cables must be linked to the timer as the cooling fan was running with just the clock /timer on but she hadn’t used oven in 3 days.so will have to have another look.
Thanks

The most likely reason is a faulty ‘Fan Time Lag Switch’ Part no : 00154836

I would think that the time lag switch would be normally open? The fault is a bit of an odd one though being as it hadn’t be used for 3 days. I don’t have a wiring diagram but it sounds like the fan has a common (shared) return, so cutting out the time lag circuit? Dunno, just guessing, sorry.
