The timer was not working on our dryer. The timer wouldn't advance no matter how long you left it on for. So, I bought a new timer and put it in today and now the timer works as expected. However, when plugged in and not running, there is a noise coming from the timer. Sounds almost like grinding or a timer slowly advancing. Also, not sure if relevant or not, but the metal cylinder/housing show in picture gets hot as well.
Is the noise and heat normal?
