Jon S. for Model Number GBD307PRS01 I noticed the other day the display on my oven was faint, however eventually it brightened and was back to normal. Yesterday while using the oven, the display went black and nothing was shown. All the buttons still seemed to work (made beeps, light worked ect.) and the oven itself seemed to work fine. Shortly after I turned it off, the display worked properly. From what I've been reading not sure if I need a transformer or a electronic control panel. Thank you in advance for your assistance.

Answer Jon, This issue will most likely be caused by a transformer that is failing and will be part number WP9760587. To test the tranformer you test by checking for 120 vac at the p16 connector between pins 5 and 7 for 120 vac and if there is power there then test from the p16 pins 2 to 3 for 12 to 24 vac. If there is no power at this point then transformer is bad. If there is power at this point then the control board is faulty. If there is no power at pins 5 to 7 then the control board is faulty.
