Since you have the temperature sensing features turned off it is most likely a dead spot in the timer.

Thanks so much, so do I replace timer? http://www.appliancepartspros.com/whirlpool-timer-99002206-ap4113205.html#qa1
If yes, is there any video how to replace/ or instructions? Appreciated

Sorry I do not have any instructions.

Usually you just remocve the inner panel to get at it.

There is some info on how to release it in the Q&A of the part.

You may be able to find a video on YouTube
