Hello, Thank you for using this service, I will be helping you with your problem today.
Good afternoon, When you say the vent fan no longer works are you talking about the key that controls it ? theres a chance this has been affected by moisture from the range below. the first thing you should try is taking a hair dryer and warming up the keys on the touchpad and massaging them with your fingers. sometimes this will fix the keys. if not you will have to replace the keypad. heres a link to order it if needed. http://www.repairclinic.com/PartDetail/Touchpad-and-Control-Panel/WB56X10816/1474862?modelNumber=HVM1540DN1WW?RCAID=1000065 I hope this helps, have a great weekend ! thanks .
