Hi, welcome to Just Answer. My name is ***** ***** I look forward to helping you!
Turn the left hand temperature control knob to just after 50 degrees so that it is lines up with the lock symbol on the clock, then hold in the + button for 3 seconds. Any change?
May I please have your model number so I am able to provide you with accurate, model specific information?
I am not sure then, that model shows two knob controls, see link below.
